Characteristics of respiratory viral infections during influenza season in Canadian Hutterite Communities.
OBJECTIVE
To determined the pathogen-specific incidence of respiratory virus infection in Hutterite communities occurring over the 2008-2009 influenza season and assess temporal characteristics of respiratory illness related to infection.


METHODS
3273 participants community members enrolled in a cluster randomized trial of influenza vaccine were studied.


RESULTS
One hundred forty-nine participants had laboratory-confirmed influenza, and 595 had at least one episode of laboratory-confirmed respiratory viral infection other than influenza. Entero/rhinovirus had the highest incidence among children<5 years.


CONCLUSIONS
A decline in the incidence of infections with age was observed for influenza as well as for most other respiratory viruses.
