CDC launched a new influenza A(H5N1) webpage that shows how CDC is actively assessing multiple indicators during the current avian influenza A(H5N1) situation to monitor for spread of the virus to or among people in jurisdictions where influenza A(H5N1) has been identified in humans or animals. The new webpage consolidates existing data already publicly available on other CDC sites. Data that is displayed on this site include:
- jurisdictions that report an influenza A(H5N1) virus infection in 2024,
- national and regional results of public health laboratory testing,
- national and regional percentages of specimens tested that are positive for influenza A viruses, and
- national, state, and local level (where available) National Syndromic Surveillance Program emergency department visits associated with influenza diagnoses and symptoms potentially related to influenza infections.
