Spread of Swine Flu
Tim Nolan on the BMJ group Blogs comments on the spread of swine flu and how the spread has been calculated:
“We’re saying there have been at least a million cases of this new H1N1 virus in the United States so far this year. “
That’s according to the Centre for Disease Control (CDC) who held a press conference on Friday which shed some more light on the epidemiology and spread of the disease.
So how was this huge figure (over thirty times the number of confirmed cases) calculated?
