Transmission of Novel Influenza A(H1N1) in Households with Post-Exposure Antiviral Prophylaxis

Abstract

Our results indicate that the overall household transmission levels of novel influenza A(H1N1) in antiviral-treated households were low in the early stage of the epidemic. The relatively high rate of adult-to-child transmission indicates that control measures focused on this transmission route will be most effective in minimizing the total number of infections.
