Superb Flu Pandemic Risk Communication: A Role Model from
Australia
by Jody Lanard and Peter M. Sandman
Posted: July 6, 2005
This column builds on our December 2004 column “Pandemic Influenza Risk
Communication: The Teachable Moment.” Readers unfamiliar with the H5N1
avian influenza pandemic threat and its risk communication implications
may want to read the prior column before this one.
Government communication about pandemic influenza continues to be
generally disappointing. As the bad news mounts in places like China and
Vietnam, and the concern of experts mounts along with it, too many
national and local governments have had little to say, and too much of
that little has been over-reassuring bordering on misleading.
So we have been keeping an eye out for good examples. We’ve found a
few, most of them local. But by far the best example comes from
Australia’s national government, in an early May speech by Health Minister
Tony Abbott. We have decided to devote a column to Minister Abbott’s
speech, hoping for human-to-human transmission of great pandemic risk
communication.
We had been monitoring Australia’s pre-pandemic communication since we
read Chief Medical Officer of Health John Horvath’s over-reassuring news
release on February 25, headlined “Australia
Well-Prepared to Combat Bird Flu.” Before celebrating Abbott’s
wonderful speech, we want to spend a few paragraphs on Dr. Horvath’s much
more typical — not horrible, just typical — example.
“Australia is one of the most prepared countries in the world to detect
and manage Avian Influenza,” Dr. Horvath accurately stated in the news
release lead paragraph. What he didn’t say, anywhere, is that even the
most prepared countries in the world are woefully unprepared. There were
no hints in his news release that a pandemic might be a disaster, despite
Australia’s excellent technical planning effort.
Instead, the release talked about the millions of dollars Australia has
budgeted “to protect Australians from potential outbreaks of human
pandemic influenza,” boasting that “Australia has a contractual commitment
for the supply of up to 50 million doses of pandemic vaccine should there
be an outbreak of pandemic influenza.” Unmentioned were these facts: that
there is as yet no pandemic vaccine; that efforts to develop one are going
slowly; and that most experts believe it will take at least three to six
months to produce such a vaccine once a pandemic strain of influenza is
identified.
If they are believed, over-reassuring statements like these can
actually damage one crucial aspect of pandemic preparedness — public
awareness and involvement. Australians who read only the Horvath news
release would have been justified in assuming that pandemic preparedness
was under control, and that there was no need for them to pay any further
attention. Of course once a pandemic arrived and proved difficult to
manage, such readers would very likely have suffered a loss of confidence
in their leaders — just when confidence was most needed. Even before
over-reassuring statements are proved wrong, moreover, they can have a
paradoxical impact. Readers who are skeptically inclined or have other
sources of information are often alarmed by over-reassurance; the lesson
they learn is that their authorities are either over-confident or less
than candid, leaving them alone with their fears.
The most objectionable passage in the news release wasn’t about a flu
pandemic at all. It came when Dr. Horvath was discussing the lessons
learned from SARS. Because of Australia’s “well planned and coordinated”
response to SARS, he claimed, “we were able to prevent an outbreak on our
shores” — the implication being that Australia can do it again with bird
flu.
Attributing Australia’s good luck to its preventive efforts is a form
of magical reasoning. We know of only one person ever confirmed to have
had SARS while in Australia — a German tourist who arrived from Hong Kong,
developed mild respiratory symptoms while in Australia, and was diagnosed
with SARS after her return to Germany. During the peak of the SARS
outbreak, between April 5 and June 16, 2003, 77 travelers arrived in
Australia who were subsequently considered probable or suspected SARS
cases (many were eventually ruled out, while others remained unconfirmed).
Of these, 29 said they had been symptomatic at the time of airport entry
screening. But “border screening had detected only 4 (13.8%) of these 29
symptomatic travelers,” according to a Medical Journal of Australia
study funded partly by Dr. Horvath’s department. Australia did not
“prevent an outbreak” on its shores. Australia got lucky, as did the
United States and most of the rest of the world.
Even in unlucky countries like Canada and Singapore, SARS turned out to
be a lot less contagious than flu. And unlike flu, SARS is thought to be
contagious only after symptoms have begun, making screening far more
useful (at least in principle) for SARS than for flu. Nobody knowledgeable
— Dr. Horvath presumably included — believes any country can isolate
itself in an influenza pandemic and thereby prevent an outbreak on its
shores. Implying otherwise is rank over-reassurance.
So our pandemic communication surveillance antennae perked up a few
months later when we read the following May 2 Sydney Morning Herald
headline on Google News: “Nation prepared for flu pandemic: Abbott.” There
they go again, we thought, another over-reassuring official statement out
of Australia. We were wrong.
The headline was misleading. The actual article, covering Minister
Abbott’s speech at a major infectious disease conference, was much more
(duly) alarming. A pandemic could be a “worldwide biological version of
the Indian Ocean tsunami.... We have to hope that this surge [of bird flu]
does not hit us…. If it does it will be something that our nation will not
forget in a hurry.... We are doing everything we reasonably can, we are as
well organised as is reasonably possible…. But I have to say if we ever do
believe a pandemic outbreak is imminent, no preparation will be
sufficient.... This is a scary prospect.”
At that point, we knew we had to see the whole
speech, which was readily available on the Australia Health Department
website. The posted speech text was a little different from the newspaper
quotations; as most good speakers do, Abbott had extemporized when he
spoke. But the tone and meaning were the same. This is some of the best
pre-pandemic risk communication we have seen anywhere.
We want to share Minister Abbott’s speech with you, along with our risk
communication annotations. If you just want to read the speech without our
interruptions, you can go to the link above.

If you want to pursue the annotations further, the numbers in brackets
refer to our list of 25 crisis communication recommendations (see box).
These recommendations are described in brief paragraphs in four handouts:
Crisis
Communication I: How Bad Is It? How
Sure Are You? [1–7]
Crisis
Communication II: Coping with the
Emotional Side of the Crisis [8–14]
Crisis
Communication III: Involving the
Public [15–18]
Crisis
Communication IV: Errors,
Misimpressions, and Half-Truths [19–25]
For more on the 25 recommendations, see the extensive
handouts elsewhere on this website.
As you read the speech (with or without annotations) it is likely to
seem pretty normal to you. It just reads like a speech — solid,
informative, but not necessarily all that special. Even Australia’s
Ministry of Health was surprised to learn that we planned a
paragraph-by-paragraph gloss. In a sense, that’s exactly our point.
Minister Abbott is saying the kinds of things government officials
normally recoil from saying. They imagine that being this candid, this
alarming, and this uncertain about anything is bound to boomerang
badly: panic the public, give ammunition to the opposition, undermine
faith in government, whatever. Abbott’s speech didn’t do any of that. In
fairness, it didn’t accomplish a revolution in pandemic preparedness
either. But the speech did treat the Australian people like adults. By
leveling with the public, it made a solid, informative contribution to an
aspect of pandemic preparedness that has been badly neglected around the
world: the preparedness of the public.
The speech text that follows is in sans-serif type in white
background. Our annotations come after the Abbott passage they comment
on.
Speech Notes for Infectious Diseases Conference, Pandemic
Preparedness by The Hon. Tony Abbott MHR
On February 4 last year, I read an urgent
brief from the Chief Medical Officer. Ministers receive all sorts of
urgent departmental documents, usually to do with cabinet,
legislative or regulatory deadlines. This one made the stuff of
daily politics and routine administration seem utterly trivial. It
advised of a possible re-run of the Spanish Flu outbreak of 1919.
Since then, a significant part of Australia’s health policy
establishment has been considering how to deal with a
far-from-merely-speculative influenza emergency which could dwarf
the health consequences of a conventional terrorist attack.
|
One principle of good risk communication
is to be explicit about preconceived points of view — anchoring frames,
or “mental models” — both your own and those of your audience [21]. This
is especially important when you want to move people to a different and
unexpected point of view. When trying to convey a message that conflicts
with people’s anchoring frames, it is crucial to construct a well-lit
path from their current beliefs to what you want them to believe, rather
than just insisting on what you want them to believe. In his very first
paragraph, Abbott shows good understanding of anchoring frames.
The paragraph offers three anchoring frames. First, ministers get
“urgent” memos all the time; usually they’re no big deal. Thus the
speech starts where Abbott himself started, and where most of his
audience presumably starts as well: unworried about flu. Then Abbott
constructs his path, by means of two much more alarming anchoring
frames. The new threat, he tells us, was as serious as the 1918–19
Spanish Flu pandemic. And for listeners unfamiliar with the devastation
wreaked by Spanish Flu, a pandemic is a “far-from-merely-speculative”
health risk that could “dwarf” the risk of terrorist attack. Australians
sensitized to terrorism by the 2002 Bali bombing (often called
Australia’s 9/11) would surely have been jolted by this third
comparison.
| Compared with World War One,
the Spanish Flu epidemic made very little impact on Australia’s
consciousness, despite the large number of deaths it caused. AB
Facey devotes just one paragraph of “A Fortunate Life” to the flu
pandemic, noting that “Western Australia had an outbreak of a very
severe kind of flu in 1920. It was called bubonic influenza and it
killed dozens of people. I got it, but only in a mild form, and we
were quarantined for three weeks. I was away from work for a month
and it was many months before I felt well again”.
Manning Clark’s History of Australia reports that in
January 1919, theatres, picture shows, pubs, race meetings and
schools were closed until further notice and that people were
advised to wear masks over their faces in public. He also reports
that people made light of the restrictions with one commentator
lamenting: “all I can do during my enforced holiday is to stay at
home and grow whiskers”.
Perhaps 12,000 deaths in hospital made comparatively little
impact alongside the 61,000 deaths in battle that the young nation
had just suffered, even though 60 per cent of flu victims were aged
between 20 and 45. Perhaps the reporting restrictions placed by many
countries (but not Australia) limited people’s awareness of the
worst disease outbreak since the Black Death had killed up to a
quarter of the world’s population in the 14th
century. |
Returning to his second anchoring frame,
the Spanish Flu pandemic, Abbott carefully and respectfully acknowledges
the low concern of most Australians about flu and even flu pandemics.
Only then does he start building his case that the Spanish Flu was the
world’s “worst disease outbreak since the Black Death” six centuries
earlier. He is helping people see that their low-concern anchoring frame
about flu may get in the way of their understanding the dire hazard of a
possible avian influenza pandemic in the near future
[21].
| World wide, Spanish Flu
killed an estimated 40 million people (compared with about 15
million killed in the Great War). Because Australia delayed the
repatriation of the First AIF, in part to avoid the flu pandemic,
the virus had lost some of its potency by the time it struck here.
In the United States, though, where it struck early, it’s estimated
that the virus severely affected 25 per cent of the then population
of 105 million with 650,000 deaths.
Subsequently, there have been two further flu pandemics: Asian
Flu in 1957 and Hong Kong Flu in 1968. Both were much milder than
the Spanish Flu outbreak with less than 500 Australian deaths in
each case, mostly among children and people over
65. |
More acknowledgment of why Australians may
have trouble imagining a flu pandemic as a major
disaster.
| Since late 2003, bird flu
has been raging through the domestic poultry stocks of South East
Asia. As of April 29, 44 people have acquired the disease, nearly
all of them living in close daily contact with domestic birds, and
19 have died. So far, there have only been a handful of possible
human-to-human transmissions, usually between family members in
close contact with someone infected. |
Many government officials around the world
— including officials in the two countries where human-to-to-human
transmission seems to have occurred — interpret the data in the most
reassuring way possible and emphasize that there is no conclusive proof
of human-to-human transmission. They are over-reassuring their publics —
or at least they are trying to over-reassure their publics; they sound
like the tobacco industry insisting to the bitter end that the evidence
isn’t conclusive. Abbott, on the other hand, matter-of-factly states
what most influenza experts believe. His use of the word “possible”
acknowledges the uncertainty [4], but he leaves the impression that,
despite absence of definitive proof, there have probably been a
“handful” of human-to-human transmissions. He is erring on the alarming
side [3] and not aiming for zero fear amongst his public [9]. Thus he is
trusting his public to bear this scary news [18], while most other
officials are not.
Since Abbott’s speech, by the way, the number of confirmed cases has
increased to 108, with 54 deaths. The evidence of occasional
human-to-human transmission is still compelling but not conclusive, and
there is no evidence yet of frequent human-to-human
transmission.
| The risk is that bird flu,
deadly and easily spread among chickens and deadly but very hard to
spread among people, could mutate into a lethal new strain of highly
infectious human flu with impact akin to the pandemic of 1918–19.
Earlier this year, the World Health Organization’s Western Pacific
Regional Director warned that the world was “now in the gravest
possible danger of a pandemic”. |
Abbott’s first sentence here is a
stunningly clear statement of why the world’s infectious disease experts
are losing sleep. The comparison to 1918–19 isn’t even necessarily the
worst-case scenario. The current H5N1 fatality rate is far in excess of
the Spanish Flu fatality rate; a true worst case would postulate that
the virus learns to transmit easily from human to human without becoming
less deadly in the process. Still, 1918–19 was the worst flu pandemic we
know about. Minister Abbott explicitly errs on the alarming side [3],
again not being afraid to scare his public [9].
Many government officials, by contrast, have based their bird flu
communications on something close to a “best case scenario,” grounded in
the fairly mild 1957 and 1968 pandemics. The frequently cited estimate
of 2 to 7 million deaths worldwide derives from extrapolating these mild
pandemics to the current world population. Officials often use the same
model to calculate a fatality estimate for their country or state or
city. They then present this fairly optimistic estimate of the bird flu
risk as if it were the worst case, “warning” that “as many as” that
number might die.
| A Commonwealth Government
report published last year estimated that a major flu pandemic could
lead to 2.6 million Australians seeking medical attention, 58,000
hospitalisations and 13,000 deaths. This is a significantly lower
mortality rate than in 1919. Health care is immeasurably improved
and Australia is considerably better prepared. On the other hand,
much greater mobility means that any new pandemic strain is likely
to reach Australia at an earlier and possibly more virulent
stage. |
Once again Abbott steers a middle course.
He cites his Government’s report estimating 13,000 deaths in Australia
in a “major flu pandemic,” then cautions that this is a “significantly
lower mortality rate” than in 1919. The implication is that 13,000 might
be right, or a pandemic might be worse than that. He has carefully
bracketed the risk comparison [25]: The Government estimate is far
higher than Australia’s “less than 500” deaths in the 1957 and 1968
pandemics, mentioned a few paragraphs earlier, but “significantly lower”
than the 1919 mortality rate.
At the end of the paragraph, Abbott offers reasons why Australia
might do better today than in 1918–19 (better health care, better
preparedness), and reasons why it might do worse (greater mobility,
leading to quicker contagion). The listener gets a sense of candor and
transparency [24] rather than propaganda. Even more important, the
listener gets a sense of inevitable uncertainty [4]; we simply cannot
know how bad an H5N1 pandemic might be. In the face of this uncertainty,
Abbott resists the temptation to lean too heavily toward the reassuring
side, which paradoxically might come across as less credible. He also
avoids the temptation to refuse to make judgments until the answers are
known. Instead he speculates responsibly [7], once again trusting the
public [18] to bear uncertain and potentially scary
news.
| A “worst case“ scenario
taken from a US draft pandemic plan, republished in version 1 of the
1999 Framework for an Australian Influenza Pandemic Plan, traces the
possible course of a pandemic from initial outbreak in a small
village in Asia:
“Over the next two months, outbreaks begin to appear in Hong
Kong, Singapore, South Korea and Japan. Although cases are reported
in all age groups, young adults appear to be the most severely
affected and case fatality rates approach 5 per cent. Widespread
panic begins because vaccine is not yet available and supplies of
anti-viral drugs are severely limited….
“A few more weeks pass and focal outbreaks begin to be reported
throughout the United States. Rates of absenteeism in schools and
businesses begin to rise…. Exaggerated accounts of illness are
reported by the media. Citizens begin to clamour for vaccine but
only 10 per cent of the estimated need is available.... Hospitals
and outpatient clinics become severely short-staffed when the
majority of physicians, nurses and other health care workers become
ill…. Intensive care units at local hospitals become overwhelmed and
soon there are widespread shortages of mechanical ventilators for
treatment of patients with pneumonia…. Family members become
distraught and outraged when loved ones die within a matter of a few
days. Looting becomes a serious problem in major metropolitan areas
due to shortages of police officers.… Further deterioration in
health and other essential community services occurs over the next
6–8 weeks as illness sweeps across the
country.…” |
Minister Abbott here offers an extended
quotation from a very candid description of a possible worst case
scenario. He is telling people what to expect [15] in a worst case, and
he is doing so with real detail and real drama. He is certainly not
aiming for zero fear [9]! Although this scenario is excerpted from a
U.S. Government document, few if any U.S. Government officials have
quoted from it this way in a public presentation. Many U.S. public
health leaders believe — mistakenly, we think — that it would be unwise
to frighten people about a possible flu pandemic.
We can’t resist commenting on three points in the scenario Abbott is
quoting.
First, note the reference to “widespread panic.” We probably won’t
get through a serious pandemic without some real panic — and panic when
it happens can be truly horrific. But even in extremely dangerous
situations, panic is rare; people may well feel panicky but their
actions are usually sensible, often helpful, and sometimes heroic. We
wish officials (and journalists) would say what they’re envisioning when
they refer to “widespread panic.” Virtually every unauthorized
precaution people decide to take is called panic by those in authority —
getting a Cipro prescription during anthrax, wearing a face mask during
SARS, even standing in line during last season’s U.S. flu vaccine
shortfall. Experts should try to be as careful when diagnosing panic as
they are when diagnosing influenza [8]. Unlike so many other officials,
Abbott does not use the fear of panic (“panic panic,” we often call it)
as an excuse to withhold alarming information [3] and alarming
speculation [7].
We’re also intrigued by the reference to “exaggerated accounts of
illness ... reported by the media.” While there will certainly be a huge
volume of pandemic coverage, experience demonstrates that media
sensationalism usually goes on vacation during a real crisis, replaced
by a sort of “Media Stockholm Syndrome.” Instead of exaggerating, the
media in a crisis will go along with official efforts to reassure; in
fact, they often downplay the most alarming information officials do
provide. Media exaggeration in mid-crisis is mostly confined to
information that reporters think has been withheld or covered up. (In
addition, media far from the crisis sometimes exaggerate. During the
SARS outbreaks, for example, media in unaffected countries sometimes ran
exaggerated accounts of illness, and often ran exaggerated — but always
vague — accounts of what they viewed, from afar, as panic.)
The fear of media sensationalism, like the fear of panic, often leads
officials to understate the risk. If he was experiencing this fear,
Abbott deserves all the more credit for not giving in to it. As we will
discuss later, the coverage of his speech was less candidly alarming
than the speech itself, especially in the headlines. The almost total
absence of media sensationalizing about avian influenza — in fact, the
repeated media tendency to downplay the risk and not use the most
alarming official statements — is perhaps the best evidence we have that
journalists, too, are worried.
Finally, note the U.S. draft’s incredibly optimistic assumption of
enough vaccine for “10 percent of the estimated need” early in a worst
case scenario [1]. Most experts believe there will be no vaccine at all
for at least three to six months after a pandemic
starts.
| Of course, it’s impossible
to say if, when and how a pandemic might develop. The next pandemic
might be comparatively mild like the flu outbreaks of the late 50s
and 60s. But it could also be a worldwide biological version of the
Indian Ocean Tsunami. There are obvious limits to how much
governments can invest in preparations for hypothetical events,
however serious. Still, responsible governments should make
extensive preparations for reasonably foreseeable contingencies. In
this respect, the WHO has recently said that Australia is as well
prepared for a flu pandemic as any country in the
world. |
This paragraph does a wonderful job of
acknowledging uncertainty [4] and sharing the dilemma about preparedness
[5]. Many officials react to accusations of inadequate preparedness by
insisting that they have done “everything possible” or even taken “every
conceivable precaution.” (Ironically, this insistence often comes from
people who previously spent decades complaining that preparedness and
the preparedness budget were both insufficient.) Abbott steadfastly
refuses to take this untenable position on the risk communication
seesaw. He concedes that there are “obvious limits to how much
governments can invest” in preparing for a crisis that may or may not
materialize. He advocates only “extensive” preparations for “reasonably
foreseeable” contingencies — making it clear that preparedness is a
judgment call, that there is no platonic essence of perfect
preparedness. This is far better than the typical dichotomous frame —
“Pandemic Influenza: Are We Prepared?” — that asks an unrealistic yes/no
question and then usually provides a misleading yes answer. The public
needs to learn, and be trusted to bear, the reality that there is no
perfect preparedness. Abbott allies with people’s mature ability to cope
[18], rather than with their less mature yearning to be over-reassured
[1].
Abbott justifiably cites WHO on Australia’s good preparedness effort,
and goes out of his way not to overstate that effort [1]. The tone of
the paragraph’s last sentence, that Australia is as well prepared as any
country in the world, strongly hints that no country can be fully
prepared.
| Australia began preparing
for a possible flu pandemic after several people died in a 1997
outbreak of bird flu in Hong Kong. All the key recommendations of
the 1999 Framework for an Australian Influenza Pandemic Plan (most
notably for a national influenza surveillance network and the
development of national and state pandemic contingency plans) have
been acted upon — except those for availability on the PBS of
anti-viral drugs because of fears that regular, long-term use of
anti-virals could help develop resistant virus strains.
In 2002, after the Bali bombing, the Government established a
National Incident Room to help monitor and co-ordinate the response
to potential health disasters. Also in 2002, the Government
established a National Medicines Stockpile, mostly to deal with a
potential terrorist incident but also to cope with natural
disasters. The Incident Room was activated during the SARS epidemic
and has been carefully monitoring the outbreaks of bird flu in
Asia. |
In documenting Australia’s preparedness
accomplishments, Abbott is careful not to overstate the case. He is
transparent [24] about the Government’s decision not to implement one of
the key recommendations in the 1999 framework, thus acknowledging a
dilemma [5], a disagreement [6], and what amounts to a recent shift in
policy [22].
| The SARS epidemic
demonstrated the capacity of national health systems, the WHO, and
co-operative neighbouring countries to monitor, treat and control
the spread of a deadly (but not especially infectious) disease.
Through the sharing of information, laboratory analyses and expert
personnel, Australia was part of an international effort to help
Asian countries contain the SARS virus with relatively minor
disruption to international travel and trade and the domestic life
of the countries most affected. Even so, it’s estimated that SARS
cost the economies of South East and East Asia a collective $15
billion (or 0.3 per cent loss to GDP) as well as 770
deaths. |
Many national leaders have said much more
over-reassuring things [1] about the way SARS helped prepare them for a
future influenza pandemic. The U.S. draft pandemic plan, for example,
states: “After the SARS response of 2003, federal, state, and local
public health colleagues conducted internal debriefings to prepare for
future outbreaks of this magnitude.“ Of this magnitude? The U.S.
had only eight confirmed SARS cases! (At the start of this column, we
also noted an Australian overstatement of SARS success.) Abbott, by
contrast, draws attention to the fact that SARS was “not especially
infectious,” that a flu pandemic would be far, far worse. He is again
telling people what to expect [15], and using an anchoring frame —
people's mental model of SARS — to make his point
[21].
| From March last year, once
it became clear that controlled culling would not readily stop bird
flu from becoming endemic in Asia, the Government began to build up
a much larger anti-viral stockpile. Anti-virals can protect people
exposed to a virus for which no vaccine is currently available.
Australia has one of the world’s four WHO collaborating influenza
laboratories and CSL (formerly the Commonwealth Serum Laboratories)
is one of the world's largest vaccine manufacturers. Still,
producing a vaccine against a new pandemic flu strain could take at
least six months because of the difficulty of producing a candidate
vaccine virus which is effective and safe.
|
Abbott leads with the reassuring
information about Australia’s anti-viral supply and vaccine production
capacity. But he then emphasizes that this doesn’t mean a quick fix. In
the structure of the paragraph, the reassuring first few sentences are
subordinated to the alarming conclusion [2].
Abbott refuses to over-reassure his public with regard to vaccines
[1]. His statement that “anti-virals can protect people exposed to a
virus for which no vaccine is currently available” is a rare example of
over-reassurance in this speech. No one knows for certain if the
eventual pandemic strain of influenza will be susceptible to antiviral
drugs — which is part of the reason why different countries have made
different decisions about stockpiling antivirals. This is one of the
dilemmas of pandemic preparedness: how much to spend on drugs that may
not be needed and, if needed, may not work.
| In last year’s budget, on
the advice of the Chief Medical Officer after consultation with the
National Influenza Pandemic Action Committee, the Government
committed $114 million to purchase 3.3 million courses of
oseltamivir (marketed as Tamiflu). Now that this order has been
filled, after Finland, on a per capita basis, Australia has the
world's largest anti-viral stockpile — on shore and ready for
use. |
This is reassuring information that Tony
Abbott has every right to convey. Australia is genuinely far ahead of
most other developed countries with regard to stockpiling Tamiflu.
Countries that have only recently decided to order large amounts of
Tamiflu will not receive their orders for many months or years. If there
is a pandemic, the output of the world’s only Tamiflu factory (so far)
may well be nationalized by its host country, Switzerland. Nonetheless,
many of these countries talk about their large orders without mentioning
the supply/delivery problem. At least they have made the orders. The
U.S., which has “on shore” only 2.3 million treatment courses (a
miniscule amount on a per-capita basis), has so far not ordered any
more.
| As part of the annual
inter-pandemic flu vaccine contract, the Government has negotiated
with CSL and Sanofi-Pasteur to supply 50 million doses of pandemic
flu vaccine should it become available. In addition, the Government
is adding to the Stockpile 50 million syringes, 40 million surgical
masks, pre-prepared equipment for six quarantine centres for 500
people for five days, along with extra ventilators and negative
pressure units for hospital isolation
rooms. |
Note the “should it become available” that
ends the first sentence of this paragraph. Unlike many other officials,
Minister Abbott is not leaning on the over-reassuring prospect of having
a vaccine supply at the start of the pandemic. He truly wants the public
to understand that there is very little chance of this [1, 15, 24].
At the start of the column, we quoted Dr. Horvath about vaccines. He
said: “Australia has a contractual commitment for the supply of up to 50
million doses of pandemic vaccine should there be an outbreak of
pandemic influenza.” In Horvath’s rhetoric, the vaccine is guaranteed,
though the pandemic is iffy. When Minister Abbott talks about the same
issue, the “shoulds” are reversed. When the eventual pandemic inevitably
arrives, he tells his audience, Australia will have prearranged access
to the vaccine — if there is any to be had. This illustrates the
difference between reassuring public relations and cautionary pre-crisis
communication.
Both before and after this speech, Australia’s Green Party accused
the Government of not doing enough to prepare for a pandemic. The
accusers seem to have no awareness that Australia has done more than
just about any other country. Remarkably, as far as we know Abbott and
other officials have managed not to retort that Australia is fully
prepared. The obvious but difficult lesson: When critics charge you with
insufficient preparedness, agree. Share the dilemma of deciding how much
preparedness is enough [5], concede that there is always more to be
done, and ask for more funding for more
preparedness.
| The Government will shortly
release the draft Australian Management Plan for Pandemic Influenza.
This sets out in detail the steps to be taken by health authorities
in the event of a pandemic flu outbreak.
In any new pandemic, the critical moment would be the point at
which the bird flu virus mutates into a new form of human flu. The
first indicator that this had happened is most likely to be large
numbers of people with flu-like symptoms reporting to hospital in a
particular town or city. Because people can be infectious for about
24 hours before the onset of flu symptoms (and for up to seven days
thereafter) the virus is likely to have spread well beyond the point
of first outbreak before quarantine measures could be
taken. |
This is much more candid, and much more
accurate, than the false promises from many other officials that “we
will reinstitute SARS-type airport temperature screening to try to keep
pandemic flu out of the country.” Because influenza is infectious before
it is symptomatic, and because it is so very contagious, any implication
that it can be stopped at the border is fallacious. A health official
who implies this, or who allows the public to infer it, is either
woefully uninformed or intentionally misleading the public [1, 23].
| According to an official
summary of an April 22 report in Science: “WHO officials are
suggesting a change in the H5N1 virus towards greater infectivity.
Together with a decrease in the case fatality rate, cases are now
occurring across all ages and in larger clusters. The officials
emphasise, though, that the results may be the result of better
surveillance and that no human-to-human transmission has yet been
observed“. |
Here and throughout this speech, Abbott is
careful to emphasize uncertainty and avoid overstating his case [4].
Yes, he says, it looks like H5N1 is getting more infective (more easily
transmitted), but it also seems to be getting less fatal, and there
still aren’t any confirmed cases of human-to-human transmission, and the
whole thing could easily be an artifact of better surveillance. Having
set a suitably alarming tone, he can now focus some attention on
reassuring details without risk of over-reassuring his audience
[2].
| Although the WHO would
formally declare that any new pandemic had broken out, it may be
prudent for Australia to commence border security measures
beforehand. The National Influenza Pandemic Action Committee is
chaired by the Commonwealth Chief Medical Officer and comprises
Australia’s leading epidemiologists and infectious disease
physicians. The Australian Health Disaster Management Policy
Committee is chaired by the Deputy Secretary of the Department of
Health and Ageing and comprises the state chief health officers plus
senior officers from Emergency Management Australia and the state
disaster agencies. The Influenza Pandemic Committee, on advice from
the observation and surveillance staff in the National Incident
Room, would advise the Government that a pandemic was imminent. The
Health Disaster Committee would then advise the Government on steps
to be taken to prevent, if possible, the spread of influenza to
Australia and to manage any outbreaks
here. |
This paragraph comes closer than the rest
of the speech to over-reassurance [1]. Notwithstanding Abbott’s interest
in launching border security measures before the World Health
organization declares a pandemic, and notwithstanding all those
committees, he must know stopping H5N1 at the border is a long shot.
Travel restrictions (domestic as well as international) are an
inevitable feature of pandemic response, and they can slow the progress
of the disease a bit — but no responsible expert believes they can stop
it. Abbott very nearly said so in an earlier paragraph. Even this
paragraph — with that nuanced “...steps to prevent, if possible....” —
concedes more than many official over-reassurances do.
| Once a decision to impose
border security measures had been made, every incoming passenger
would be required to make a health declaration, thermal scanners
would operate at international airports to detect possible flu cases
on entry and quarantine isolation areas would be established.
Influenza surveillance networks would be activated immediately and
detection and treatment information would be sent to every GP and
other health professionals such as pharmacists. Today I am releasing
a pandemic influenza awareness kit which will be sent to every GP in
the next few weeks. |
Abbott might have made it clearer here
that health declarations and thermal scanners are about slowing the
spread of influenza, not preventing its entry. As for the “pandemic
influenza awareness kit” Abbott promises to send to every GP in
Australia, his willingness — his determination — to arouse increased
concern among doctors and presumably among their patients reflects an
unusual government commitment to aim for non-zero levels of fear [9] and
to ask more of people [18].
| In a severe outbreak, health
authorities would have two objectives: first, containment to try to
prevent the spread of disease; and second, once a lethal flu strain
was generally established, maintenance of essential services. In the
early stages of a severe outbreak, the highest priority for the
provision of anti-virals would be people who had been exposed to the
virus or who worked in areas of high risk of exposure such as health
care workers and quarantine officers. Although anti-virals are
regarded as effective prophylactics against infection, their
effectiveness in treating people who are already ill is uncertain.
Anti-virals would be used to treat the most severe cases as long as
there was a reasonable chance that they might help save lives. In
later stages, if a pandemic outbreak clearly could no longer be
contained, the highest priority for anti-viral treatment would be
health and other essential service workers and emergency personnel.
No country in the world has enough anti-virals to protect
essential service personnel for the likely six months duration of a
flu pandemic, let alone to protect the general public. Even with a
much larger per-capita stockpile than countries such as Britain,
America and France, Australia could protect our one million
essential service and emergency personnel for about six
weeks. |
These chillingly candid paragraphs lay out
what officials and the public would be facing in a moderate or severe
pandemic [24]. Abbott starts with a wonderfully succinct statement of
goals, virtually conceding that the effort to “try to prevent the spread
of disease” would probably be futile, leaving officials no choice but to
focus on “maintenance of essential services.” Until very recently,
discussion of the crucial need to keep essential services functioning
despite the pandemic (not just health care and policing, but also things
like water treatment and agriculture) has been largely absent in
official pre-pandemic communications, which have emphasized mostly
treatment issues [1, 15]. Then Abbott turns to the crucial dilemma of
how to use scarce supplies of antiviral medications [5]. His answer is
firm but surely not reassuring [1]. Ultimately, keeping essential
service workers alive and healthy will take precedence over saving the
lives of everyone else — and even for this purpose, there will not be
enough medication in a bad pandemic.
These two paragraphs are among the most straightforward, candid avian
influenza statements we have seen to date from a high-level government
official. Clearly Minister Abbott wants his public to know what to
expect [15], and he expects people to be able to bear it [1, 9, 24].
Two quibbles: Abbott’s suggestion that antivirals may also be used to
treat “the most severe cases” is a little perplexing, since antivirals
are ineffective unless they’re used soon after symptoms begin, often
before the cases destined to be severe can be distinguished from the
milder ones. And most experts think a pandemic is likely to roll around
the world in several waves; each wave might last eight weeks or so in a
location, but the overall pandemic would probably last a good bit longer
than six months.
(Informational note: “Treating“ a case of pandemic flu with
antivirals implies giving a patient Tamiflu twice a day for five days —
ten pills in all. But to “protect … essential … personnel for about six
weeks” you have to give them one pill a day — 42 pills per person for
the six weeks Minister Abbott envisages.)
| For the past year, the
Government has been investigating ways to increase the availability
of anti-virals and to reduce the lead times for the preparation of
pandemic flu vaccine. Last year’s Australian anti-viral order took
over six months to deliver (and largely cornered the world market)
because of the technical complexity of anti-viral manufacture.
Despite almost unlimited potential demand, it seems that anti-viral
manufacturers have been unable significantly to expand or accelerate
their production. At current prices, anti-virals to protect one
million people for a month would cost about $90 million, if they
could be obtained. With current technology and manufacturing
processes, obtaining enough anti-virals to protect 20 million people
for six months would be almost impossible at any
price. |
Officials in several other countries, in
public relations mode, have proudly and reassuringly bragged about their
(not yet delivered) Tamiflu supplies. Abbott, by contrast, cautions that
even having “cornered the market” for six months isn’t nearly enough.
The good news (Australia is better protected than most) is here, but it
is subordinated to the bad news (Australia still isn’t adequately
protected) [2]. And the worse news: Because of both cost and
availability issues, Australia never will be adequately protected. This
has the virtues so common throughout Abbott’s speech and so rare
elsewhere: not over-reassuring [1], not aiming for zero fear [9], aiming
for total candor and transparency [24].
| All the world’s vaccine
manufacturers (including CSL) are virtually round-the-clock
investigating the production of candidate vaccines for a potential
pandemic virus. Vaccine manufacture (which involves isolating a
virus, creating an anti-virus, culturing it in sufficient
quantities, and ensuring that people can be inoculated safely and
effectively) is always a painstaking process but is particularly
uncertain for an as yet unknown and highly mutant virus. Still, the
Government is constantly talking to CSL about what might be done to
make this process swifter and more
reliable. |
Once again Abbott declines to raise false
expectations about an H5N1 vaccine [1, 15, and 24 again].
Compare Minister Abbott’s approach with recent U.S. official
communications. As we were writing this column, the U.S. House
Government Reform Committee held a hearing on pandemic influenza
antivirals and vaccines. Acknowledging that the U.S. has only enough
Tamiflu to treat 2.3 million people (which means enough to protect far
fewer), Anthony Fauci of the National Institutes of Health said NIH was
in “aggressive discussions” with manufacturer Roche about buying another
two million treatment courses. Aggressive discussions to do what? Join
the long line of countries already queued up for Roche’s next few years
of Tamiflu production? Jump the line? Not to mention the paltry
percentage of the U.S. population even this second order would cover.
According to a June 30 Associated Press story, Fauci “noted that
Tamiflu is difficult and time-consuming to manufacture, which ‘makes it
important for us to get our bid in now.’” — as if now were early
and orders weren’t backlogged for years. AP added: “Other countries are
depending mostly on Tamiflu to fight a bird flu outbreak, while the U.S.
also is stockpiling vaccine and would use Tamiflu more to buy time until
even [“even”?] more inoculations could be made, said Dr. Bruce
Gellin of the National Vaccine Planning Office.” This isn’t an exact
quotation from Gellin. We can hope he didn’t actually claim the U.S. has
a usable vaccine stockpile. The U.S. has indeed stockpiled some two
million doses of one experimental vaccine against one H5N1 strain,
thought to be enough to vaccinate a million people (two doses each) if
it works. And a different experimental H5N1 vaccine is now in its first
clinical trials, being tested for safety and immunogenicity on several
hundred U.S. citizens. The trials will not prove the vaccine’s efficacy
against the eventual pandemic strain, and of course there is no
stockpile.
| Once pandemic flu was
present in the Australian community, depending on its severity, the
Government would have to decide whether to discourage or ban large
gatherings and close schools. Any such measures would have serious
economic consequences but they could slow the spread of disease and
allow more people to be protected by any vaccine that's ultimately
developed. Once pandemic flu had spread beyond designated quarantine
areas, the Government would also have to decide whether to rely on
home quarantine of flu cases with mobile medical teams treating most
patients and designated hospitals dealing only with the most serious
cases. |
“The Government would have to decide....”
is a wonderfully candid way of telling people what to expect [15],
acknowledging uncertainty [4], and above all sharing dilemmas [5].
Obviously these are painfully difficult decisions the Government has not
yet made. In contrast to Abbott, officials usually keep mum about
pending decisions, especially frightening and depressing ones; after a
decision is made, officials usually announce it as if it were obvious,
without acknowledging the painful, difficult discussions that led up to
it.
| Not since World War Two have
Australians had to cope with very large numbers of premature deaths.
Australians are unused to contemplating the possibility of death on
a massive scale, especially from “natural causes”. The competing
temptations are “it won’t happen here” complacency, “there’s nothing
we can do” fatalism, or “no precaution is too great”
alarmism. |
This is a spectacular paragraph that puts
on the table some of the public’s anchoring frames as it listens to
warnings about a possible pandemic [21]. Note two unusual things about
how Abbott sees the public’s anchoring frames. First, his worry about
alarmism isn’t framed in terms of panic, but rather in terms of the
impulse to go overboard on precautions. He’s not engulfed by “panic
panic“; he just wants to keep reminding people that there are limits to
how much preparedness is feasible for a risk that may never materialize
[8]. By contrast, most officials are so preoccupied with their fear of
public panic that they end up pretending that they have already taken
all conceivable precautions. But Abbott doesn’t stop there. The second
unusual thing about the paragraph is how it pays attention to emotions
other than just fear [10]. Abbott is worried also about complacency and
fatalism — risks far likelier than panic and almost never mentioned in
official discourse about avian influenza.
Talking about “‘there’s nothing we can do’ fatalism” gave Abbott an
opening to talk about what people can do to help prepare
themselves and their communities for a possible pandemic. One of the few
serious weaknesses of this speech is its failure to offer people things
to do [16] — ideally a choice of things to do [17], so their ability to
act is supplemented by their ability to decide. Involvement and efficacy
are among the most potent antidotes to the fatalism Abbott is worried
about. And if what Abbott calls “complacency“ turns out to be more
denial than apathy, involvement and efficacy are potent antidotes to
that as well.
| All these grave scenarios
come from material already published and in the public domain. Even
so, it’s hard to discuss potential disasters outside people’s
ordinary experience without generating the sort of lurid headlines
which make some scoff and others panic. It’s important not to
over-react to potential threats. On the other hand, people and their
governments need to take credible threats seriously and take
reasonable and proportionate precautions against them. If a deadly
flu pandemic ever seems imminent, no preparations will be enough.
But if the current bird flu outbreaks in Asia gradually subside, the
Government’s investment in a stockpile likely to be time-expired in
five years will be the health equivalent of a redundant weapons
system. |
Again, Abbott does wonderful
dilemma-sharing, while also telling people what to expect and
acknowledging uncertainty [5, 15, 4]. Look at the structure of this
paragraph: It’s important not to over-react ... but we need to take the
threat seriously. If a pandemic comes no preparations will be enough ...
but if the risk subsides we will have wasted our investment. Back and
forth he goes on the risk communication seesaw. Unusually candid about
both sides of the dilemma, this paragraph helps us find our way to the
fulcrum, where we can face both sides at once.
Abbott is trusting the public to bear the weight of the truth. Even
though this speech doesn’t offer people things to do [16, 17],
emotionally it asks a great deal of them [18]. If a pandemic comes,
Australia’s public will be that much better prepared. By contrast, most
officials around the world do not trust their publics to bear this
weight. Less prepared for the pandemic if it comes, their publics will
feel blindsided and misled; they will be less ready to cope, less likely
to cooperate, and more inclined to blame their leaders. In Australia
like everywhere else, people naturally yearn for “perfect protection.”
It is tempting but profoundly unwise for leaders to cater to this
yearning. Abbott allies instead with our more mature, more resilient
traits.
Abbott was understandably wary of generating “lurid headlines,”
panic, and scoffing. But as we have noted, the media usually abandon
sensationalism when the risk is serious, and media coverage of Abbott’s
speech was anything but lurid. There were no reports of panic, though we
can hope some people were appropriately alarmed by his speech. The only
scoffing we found was the Green Party saying he wasn’t doing enough.
This paragraph and the preceding one add up to a very respectful
acknowledgment of public emotions. And Abbott does not ridicule these
emotions [11]. Instead, he matter-of-factly points out that some people
may understandably over-react, while others may understandably
under-react. This point in the speech would have been a perfect moment
to empathize with these early reactions — whether scoffing or scared —
and then to point out that people naturally need time to absorb bad news
before getting down to the business of proportionate preparedness [13].
| Since 1998, and with much
greater urgency since late 2003, all Australian governments have
been preparing for a flu outbreak that might, if not prepared for,
overwhelm the health system and paralyse normal society for months.
Those preparations are far from complete. It’s clear that we cannot
guard against all contingencies and that a severe outbreak would
test our national capacity in ways unknown for half a century. Even
so, much work has been done and it's important that experts and
policy makers take the Australian public into their confidence lest
people one day say they had never been
warned. |
If any reader still wonders whether
Abbott’s speech is merely accidental good risk communication, this
sentence should answer the question. Abbott is dramatically insisting
that the public be told — and bear — the frightening prospect of a
pandemic, the realities about preparedness, and the uncertainty
surrounding it all. He knows and says what most officials around the
world are ignoring or denying: that people can take bad news, and that
they will eventually punish any leader who withholds that bad
news.
| Frequent (and frequently
exaggerated) public controversy notwithstanding, Australia has a
very good health system with generally advanced equipment and
infrastructure and highly professional and dedicated health staff.
Our “have a go” culture means that we can usually improvise to meet
the unexpected or the daunting. Precisely because it is a good
system, people have very high expectations that it will cope under
any circumstances. |
Abbott moves toward his close with another
explicit acknowledgment of the public’s anchoring frames — both its
accurate sense that Australia usually copes well with problems and its
unrealistic sense that anyone can cope well with a serious pandemic
[21]. We also like the reference to improvisation, where most officials
would focus exclusively on planning. This accurately reflects the
reality that in a crisis resilience often counts for more than
preparedness. And it’s a subtle warning that if and when the pandemic
comes, everyone will be improvising in response to uncertain and
unprecedented events, and that errors and failures and disagreements are
therefore inevitable [4, 5, 6].
| At every level, the
officials and experts involved in pandemic preparedness have been
fully alive to the urgency of the task and determined to get things
done. So far, they’ve well and truly confounded the stereotypes of
government by committee. On the record so far, Australia’s health
security is in good hands. This should be some consolation to those
tempted to dwell on the fear and confusion which would inevitably
accompany a deadly scourge. |
The two “so far’s” are more realistic and
more humble than the usual self-congratulatory tone in official
speeches. Paradoxically, this sort of candor probably inspires more
confidence than a PR-dominated promise to be ready for whatever comes
[24]. And that last sentence! The Government’s good job so far “should
be some consolation” — but only some, since “fear and confusion” are
inevitable. This is not the traditional over-reassuring “upbeat” ending.
In his last sentence Abbott chooses instead to legitimize people’s
appropriate fear of an influenza pandemic [1, 12].
A Postscript on the CoverageReporters covering Abbott’s speech
conveyed his frank, “duly” alarming content well. They didn’t
sensationalize it, and they didn’t treat it as a huge story — but they
covered it accurately.
The headlines were another story — literally. All the headlines
reflected the dichotomous thinking typical of headline writers. Only one
online headline that we could find chose the alarming side of the
dichotomy, obviously the right side for Abbott’s content (if you accept
that a nuanced middle is unachievable in headlines). “Australia not ready
for flu,” wrote The Australian on May 2, 2005. Numerous other
headlines erred on the reassuring side:
- “Nation prepared for flu pandemic: Abbott” (Sydney Morning
Herald, May 2; the same headline was used in The
Age/Australia, also May 2)
- “Aust prepared for flu pandemic: Abbott” (ABC/Australia, May
2)
A month later, when Australia released its pandemic plan, Abbott told
reporters about Australia’s excellent pandemic planning, but cautioned,
“On all the best advice we have, we’re looking at a whole lot of pretty
grim possibilities.... I think we need to be very concerned — not
panic-stricken — but concerned.” He talked about the need to keep
essential services up and running while a vaccine was developed, adding:
“We cannot be certain that any candidate vaccine would be effective.” The
headline on most of the online articles covering Abbott's statements on
June 6? “Australia ‘prepared for flu pandemic.’”
Between Abbott’s May 2 speech and the June 6 release of Australia’s
pandemic plan, we spent time in Perth and Adelaide, where we found very
few people who were aware of the prospect of an avian influenza pandemic,
and virtually no nonmedical people who were concerned about it. Adelaide
held a four-day “bird flu response exercise” (called “Adventurous Goose“)
while we were there; it received virtually no media coverage. Even Tony
Abbott is having a hard time getting people concerned, let alone alarmed,
about a pandemic. But at least he is trying.
