HOW DO WE KEEP TRACK OF INFLUENZA-ASSOCIATED HOSPITALIZATIONS?
The Emerging Infections Program (EIP) is a population-based network of the CDC and state health departments to assess the public health impact of emerging infections and to evaluate methods for their prevention and control. Maryland joined EIP in 1997 and now participates with nine other states. The Emerging Infections program consists of two components- the Active Bacterial Core Surveillance and the Foodborne Diseases Active Surveillance Network.
With regards to influenza surveillance, EIP receives and analyzes reports from participating hospitals on hospitalizations associated with influenza. Currently, 44 of 46 acute care hospitals in Maryland are participating in this program.
To be a case, a person must be hospitalized and have a positive influenza test (of any kind).
