Respiratory Virus Surveillance
Laboratory-based surveillance for influenza, SARS-CoV-2, and other respiratory pathogens is coordinated by the Wisconsin State Laboratory of Hygiene (WSLH), in collaboration with the Wisconsin Division of Public Health and the Centers for Disease Control and Prevention (CDC).
This surveillance network utilizes a combination of laboratory testing data along with respiratory specimens submitted to the WSLH for additional surveillance testing and characterization. Specimen requests are modified as the level of influenza and other respiratory virus activity changes and as other circumstances require. These changes will be communicated in the bi-weekly “Laboratory Surveillance Report” which is posted at the WSLH website under the Surveillance tab.
Contributing elements of the laboratory-based surveillance for Wisconsin include enrolled sentinel surveillance sites, university health clinics, and any laboratory performing PCR/molecular or antigen testing for respiratory viral pathogens. In addition to submission of specimens for surveillance testing, these sites provide weekly testing data including the number tested and number positive for respiratory and gastrointestinal pathogens impacting community health.
The complete Laboratory-Based Surveillance Plan for the 2024-25 season is available.
