Household transmission lower for H1N1
A study of household transmission of the novel H1N1 virus in San Antonio, Tex., during the first pandemic wave found that children were most affected and were more likely to transmit the virus to other children at rates that were generally lower than seasonal flu. The median time to illness onset between contacts was 4 days. The Emerging Infectious Diseases study found secondary attack rates of 4% for confirmed novel H1N1, compared with rates ranging from 13% to 30% for seasonal flu.

Study cites obesity as risk factor for severe H1N1
To identify risk factors, French researchers compared the frequency of preexisting health conditions in patients who had severe H1N1 flu with their frequency in the general French population. Writing in PLoS Currents, an online journal that screens content but does not use full peer review, they report that pregnancy, obesity, heart failure, and diabetes were risk factors for admission to an intensive care unit. But only obesity, heart failure, and diabetes were risk factors for death.
