Influenza Hospital Surveillance
Healthcare Associated Infections

Surveillance for adult and pediatric influenza-related hospitalizations is a collaborative project between U.S. Centers for Disease Control and Prevention (CDC - EIP), Oregon hospitals' infection control staff, Oregon Public Health Division's Emerging Infections Program.

The project began because of an unusually early start to the 2003-2004 influenza season coupled with reports of influenza-associated complications and deaths in children.

As a result, the EIP states began conducting population-based surveillance to assess the burden of influenza in pediatric patients. Adult influenza hospitalization surveillance began during the 2005-06 influenza season and expanded upon the existing pediatric surveillance structure. The primary objective for these surveillance projects is to determine the rate of influenza among these populations as well as describe the characteristics of children and adults with severe flu. These projects also contribute to evaluations of current influenza vaccine recommendations.
