Transmission of pandemic H1N1 2009 influenza in households and school settings: comparison with seasonal influenza

摘要

Knowing how influenza virus is transmitted at home and in school is the key to preventing its spread. At the previous two meetings of this Conference,1'3 we introduced our study of household transmission of seasonal influenza and reported our conclusion that protracted survival of the virus even after treatment increases household transmission, and is a major factor in the transmission of the virus to infants. On the other hand, during the recent pandemic, many schoolchildren developed serious respiratory tract disorders, which again highlights the significance of school-based transmission of the disease. In this study, we compared transmission of a new influenza strain at home and in school with that of seasonal influenza and proposed countermeasures.
