This flu seems particularly prevalent among people under 18, for reasons no one can particularly explain.
From Margaret Chan (head of WHO) today:
"We know that the novel H1N1 virus preferentially infects younger people. In nearly all areas with large and sustained outbreaks, the majority of cases have occurred in people under the age of 25 years.
In some of these countries, around 2% of cases have developed severe illness, often with very rapid progression to life-threatening pneumonia.
Most cases of severe and fatal infections have been in adults between the ages of 30 and 50 years.
This pattern is significantly different from that seen during epidemics of seasonal influenza, when most deaths occur in frail elderly people."
