With respect, I have to agree with a previous comment by gsg that we don't have the depth of experts willing to participate in this FT debate in order to come up with some reasonable probabilities. That's not meant to dissuade participation or comment; however, it is a general request for an analytical framework when considering probabilities. It just seems to my limited mind that the opinions of the populace on the liklihood of a pandemic involves a completely different research methodology than the question of H5N1's ability or inability to mutate towards pandemic potential. I would like to see the social scientist who read FT to delve into the question of estimating and expressing through some number, index or indicator (doomsday clock ?) our fears or indiference about a pandemic. At the same time I would like to understand from the mathematical, natural science and epidemiolocal worlds whether probability estimates could be generated for the various biological changes necessary, and the animal interactions necessary, for pandemic development.
I agreed that this will put some real points. The WHO have/not have (?), officialy to deliver such an estimate? If we realy want to see this info (not in this thread - it is proclamed to be an idividual sensitive opinion), an real scientific estimate about an human pandemic (not only for 5 years, but 3 or 6 months, 1 or 2 years), maybe is necessary to found a formal way to ask the public scientific experts (WHO, CDC, etc.) to publicate on an scientific journal (Nature, ...) their result of this analytical framework of pandemic probabilities.
And even from the financial/economic worlds, where business and stock cycles, and the social/psych basis for them, have been studied ad infinitum, how would they model and estimate the probability for a pandemic?
The media reported an fin./ec. study result taken at G8. The study is classified, or for public (?) maybe somebody have this info.
We can calculate the expected number of accidents due to the curvature in highway cloverleafs; we can predict when a tiger is going to strike ("Life of Pi"); we can write complex programs to make money; and we can survey the populance with an accuracy of 19 times out of 20.
So what are the experts thinking about the probability of a lethal, influenza pandemic?
Good point to start. Here are some news from "FluWiki", how last month, a collaboration of European and Asian researchers launched a new attack against the deadly bird flu virus, harnessing the combined power of more than 40,000 computers across 45 countries to boost the pace of anti-viral drug discovery.
Breaking News: Chinese University Uses EGEE to Battle Bird Flu
BUDAPEST, Hungary, Oct. 4 -- Last month, a collaboration of European and Asian researchers launched a new attack against the deadly bird flu virus, harnessing the combined power of more than 40,000 computers across 45 countries to boost the pace of anti-viral drug discovery.
Called Enabling Grids for E-sciencE, the computing grid connects ordinary PCs to form a super-sized supercomputer that is being used during this challenge to analyze the potential of more than 500,000 drug-like molecules over the next few weeks.
This effort comes as new data released last week by Peking University in Beijing, China, shows that the H5N1 bird flu virus can pass through the placenta of pregnant women to the unborn fetus, and can infect organs other than the lungs in adults.A rapid response to any pandemic outbreak of the virus would be essential to its control.
Dr. Ying-Ta Wu, biologist at the Genomics Research Center of the Academia Sinica, says computing grids like EGEE are the fastest and cheapest way to discover new drug leads.
“We are using EGEE to find new molecules that can inhibit the activities of the influenza virus,” explained Wu. “During previous challenges using the EGEE grid we discovered about 200 molecules with the potential to become drugs against bird flu.”
The EGEE computing grid powers drug discovery software that allows researchers to compute the probability that a drug-like molecule will dock with active sites on the virus and thus inhibit its action.Using the results of such in silico screening, researchers can predictwhich compounds are most effective at blocking the virus. This accelerates the discovery of novel potent inhibitors by minimizing the non-productive trial-and-error approach in a laboratory.
“Asian flu remains a threat to world health and we are well aware that any pandemic could quickly spread throughout Europe," said Viviane Reding, European commissioner for Information Society and Media."I am pleased that the European project EGEE has found such an important application for computer grid technology as speeding-up drug discovery against neglected and emerging diseases.Collaboration between Europe and Asia is essential if we are to address world wide threats to public health."
At the EGEE’07 conference in Budapest, Ulf Dahlsten, director of Emerging Technologies and Infrastructures in the Information Society and Media Directorate-General of the European Commission, used the example of EGEE’s success with bird flu to illustrate the potential contributions of e-Infrastructures to science."Computer grids have achieved a productivity increase of more than 6,000 percent in the identification of potential new drugs," he said. "300,000 molecules have already been screened using the EGEE grid. Of these, 123 potential inhibitors were identified, of which seven have now been shown to act as inhibitors in in-vitro laboratory tests.This is a 6 percent success rate compared to typical values of around 0.1 percent using classical drug discovery methods."
About EGEE
The Enabling Grids for E-sciencE (EGEE) project is funded by the European Commission. The project aims to provide researchers in both academia and industry with access to major computing resources, independent of their geographic location. For more information see http://www.eu-egee.org/

Laidback Al, tropical, you won't write these 100% thingies in my probability thread
without me objecting...
There is some chance, that mankind will die before the next pandemic comes.
We might be able to beat flu-viruses in some decades, so we can prevent
flu-pandemics.
Annez, it isn't really calculated, more estimated.
You could split it into independent events/questions and answer them separately
and estimate their probabilities. That should increase the reliability of the estimate.
pandemic from an existing, known, unchanged strain
pandemic through point-mutations only
pandemic from a reassorted virus
pandemic from a virus recombined from reasonably different other viruses
and then split these again etc.
and then ask the experts for their estimates on each of the sub-questions,
and watch where they disagree most and let them discuss that.
Laidback Al, tropical,you won't write these 100% thingies in my probability thread without me objecting...
If you read carefully, we didn't write anywhere texts of 100% probabilyties that it will happen in 1, 2, 10, or 50 years. Quite the oposite.
Laidback Al statement This is worth repeating. It is 100% certain that there will be another pandemic. We just don't know when. So planning for it just makes good practical sense.
This 100% event is an math apstraction, because is stated without an time dimension.Like "it is 100% certain that the great piramides will fall in dust", yes, but when?
The 100% here is because we know that during the human history were few flu pandemic for sure. Than, mathematicaly, there are no reasons why this events must stop now, and because of this, some kind of flu pandemic will 100% certainly came, but for this thread discussion probabilities it is unknown when.
From me:

You can get the "calculated %" only from an scientific research publication.
Like wroted in (*).
If this is unaceptable, then FT must form one multidisciplinar team for "scientific calculations of pandemic probabilities", an equipe of eminent researchers, and than you maybe got an detailed answer.
Is it possible on FT?
This will be the hardly way of doing estimates here...
I think, the experts should do it, not FT.
As the CDC-panels in 1976.
would you also consider another cholera pandemic as 100% ?
Plague ? Advacing science can eliminate diseases,
no matter about history.
Obviously it is better that WHO experts should do it, but you put your commentaryes on a FT thread ofsubjective post of privateopinions!

Cholera and plague are not flu viruses!
Now you negate the possibility of an flu pandemic at all, or near... WHO warnings are illusions? Than prove it!
I think that yours want to be an anti-preparedness statement.
Why your perseverance of downplaying the risk of a novel flu?
Is it so important the % number of a probability?
If somebody calculate that is 100%, something can change, and there will be no pandemic.
If somebody calculate 0%, something can change, and the pandemic will starts.
Prepared the health, and other sectors without doing the preps years before an pandemic is not possible. It's logic, you don't need calculations.
For that reason, the start of this preparations must coming from the official establishments, not from citizens!
This FT thread is "for citizens", and about their:

Communicating Uncertainty , Fulfilling the Duty to Inform
================================================== ============
Scientists are often hesitant to share their uncertainty with decisionmakers
who need to know it. With an understanding of the reasons for their
reluctance, decisionmakers can create the conditions needed to facilitate
better communication.
----------------------------------------------
Reasons for reluctance:
Experts see uncertainty as misplaced imprecision.
Experts do not expect uncertainties to be understood.
Experts anticipate being criticized for communicating uncertainty.
Experts do not know how to express their uncertainties
-------------------------------------------------
Explanation of uncertainty terms in intelligence analysis
What we mean when we say: An explanation of estimative language
----------------------------------------------------
The decisionmakers’ role
If experts see little value in expressing their uncertainty,show how decisions depend on it
If experts fear being misunderstood, insist that they trust their audience
If experts anticipate being punished for candor, stand by them
If experts are unsure how to express themselves, provide standard means.
