Bigger than 1918? "If you're talking about mortality then it's different. 1918 is the biggest in terms of mortality. I would not like to make any predictions . . . I hope we don't see the 1918 picture. But we should expect to see more people infected, and more severe cases coming up, including deaths."
Swine flu is probably already much bigger than anyone knows. Ten days ago, only six countries in Africa had reported cases, but as Chan readily admits, this is rather misleading: until the WHO started sending out lab kits in early May, many developing countries had no means of testing for it. Furthermore, modelling suggests that swine flu has an attack rate of 30% — once it enters a country, the likelihood is 30% of citizens will catch it at some point.
