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

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

Nice catch GD.
