Virology Surveillance




Laboratory-based surveillance for influenza and other respiratory viral pathogens is coordinated by the Wisconsin State Laboratory of Hygiene (WSLH) in collaboration with the Wisconsin Division of Public Health. This multi-element laboratory-based surveillance program has enabled us to achieve the four key objectives of routine respiratory virus surveillance:

  • Providing situational awareness
  • Detecting novel viruses
  • Informing influenza vaccine strain selection
  • Detecting and monitoring antiviral resistance

Contributing elements of the laboratory-based surveillance for Wisconsin include rapid antigen testing sites, PCR laboratories, enrolled clinical laboratory surveillance sites and health care provider sites. In addition to surveillance specimens, these sites provide weekly testing data including the number tested and number positive for many viral and bacterial pathogens impacting community health.
