The Bird Flu is Comming! The Bird Flu is Comming!

I have problems with that number. The 1918 flu epidemic killed between 20 and 40 million people. World population was perhaps 2 billion at the time (earliest numbers I can find are for 1950, and population was 2.5 billion). That's 1% of the world population. One out of every one hundred people died. And that includes everyone, not just infected. So "a couple of deaths per 10,000 people" is a gross understatement of the death rates possible with an influenze epidemic. True, 75% is absurdly high, but I'm not even particularly comfortable with the 1-2% represented by the 1918 pandemic.

That being said...I think it's possible to mitigate the risks without resorting to the sensationalism and fear-mongering that people seem to like.

I tracked down Dr. Longini. Here is the response he sent:

the case fatality rate for 1957 h2n2 and 1968 h3n2 was on the order of
1-2/10,000 when averaged over all age groups. for 1918 it was on the
order of 1-5/100, two orders of magnitude higher. however, that very
high rate was before antibiotics that are now use to treat secondary
bacterial pneumonia. probably the major killer of for flu cases. this
would be of no use against primary viral pneumonia. in our recent work,
we tend to stay away from predictions of case fatality rates for
pandemic flu. a big unknown. cheers, ira longini

So basically he's admitting he was wrong when he said "in recorded or even unrecorded history"

Nice catch GD.

I'm convinced that majority of the sensationalized news over the bird flu (and other stories of that nature) are all just planted by major companies to drive their particular businesses sales and stocks up. Gas? Pharmaceuticals? Housing shortages? It's all is driven by fear and speculation. All the money fear can generate. Is my skepticism showing much?
