Laboratory Testing & Surveillance Data Reports

Health care providers submit specimens to the Health Department Laboratory for influenza testing. These tests allow us to determine the presence and type of influenza virus in the specimen. Since influenza viruses are constantly evolving, this information serves as an indicator of which types are currently circulating in the community. More about Laboratory Influenza Testing

About Laboratory Influenza Testing

The Health Department Laboratory offers influenza testing throughout the year. Due to limited resources the Health Department will only provide influenza testing by RT-PCR to:

Sentinel providers as well as EARS enrollees are provided influenza specimen collection kits and testing at no cost. This helps influenza surveillance efforts by supplying the Laboratory with specimens that can be used to further characterize influenza.

Long-term care centers and other institutions experiencing outbreaks of influenza-like illness or providers with special circumstances will be provided with free influenza specimen collection kits and testing. Please arrange testing by calling: 1-802-863-7240 or 1-800-640-4374.

For influenza specimen collection supplies and laboratory information, medical providers may call the Health Department Laboratory at 1-800-660-9997 or 802-863-7335.

Sentinel Provider Data [PDF]
This chart represents the sentinel provider data reported on a weekly basis to the national ILINet system.


Sentinel providers conduct surveillance for influenza-like illness (ILI), in collaboration with Health Department and the Centers for Disease Control and Prevention.

The data reported by the sentinel providers - in combination with other flu surveillance data - provide a national picture of influenza virus and ILI activity. Sentinels report the total number of patient visits each week, and the number of patient visits for ILI by age group.
