Expert: Pandemic definition should exclude severity
Though many are calling for the World Health Organization (WHO) to incorporate severity into its pandemic alert phases, a renowned virologist is saying no. Malik Peiris of the University of Hong Kong said there was no doubt novel H1N1 was a pandemic, well before the WHO declaration. "We really don't have good assessments of severity," he told The Hindu. "So it would completely paralyze international public health policy, I think, if severity is linked to the definition of a pandemic."

Study shows rates of antibodies to H1N1 varied by country
A seroprevalence study of 7,962 people aged 1 to 60 years found that, from August to October 2009, people had these rates of antibodies to pandemic flu: Costa Rica (26.4%), the United States (22.5%), Switzerland (16.9%), Germany (12.6%), Belgium (10.1%), and Japan (5.9%). The authors write, "The low proportion of seropositive children in Europe and Japan suggests that little local viral transmission had occurred." They say the data show that public health steps in late 2009 were justified.
