Public Release: 

Serology studies could inform pandemic flu plans


In this week's PLoS Medicine, Steven Riley, from Imperial College London, and colleagues analyze a community cohort study from the 2009 (H1N1) influenza pandemic in Hong Kong, finding that more children than adults were infected with H1N1, but children were less likely to progress to severe disease than adults. The authors recommend that revised pandemic preparedness plans should include prospective serological cohort studies, such as this one, in order to be able to estimate rates of severe disease per infection.
