Influenza-like Illness Surveillance Program (ILINet)

Now You Can Help With Influenza Surveillance in Only a Few Minutes a Week!

The ILINet Program is a national outpatient influenza illness surveillance program. Healthcare providers (ILINet Providers) that participate in the program report information on patient visits for influenza-like illness (ILI) collected through the U.S. Outpatient Influenza-like Illness Surveillance Network (ILINet). The national ILINet Program consists of more than 2,700 outpatient healthcare providers in all 50 states, the District of Columbia and the U.S. Virgin Islands reporting more than 30 million patient visits each year. The New York State (NYS) ILINet Program consists of 173 providers in various specialties covering 36 counties.

Data reported by ILINet providers, in combination with other influenza surveillance data, provide a state and nationwide picture of influenza virus and ILI activity.

NYS ILINet providers submit patient specimens to the NYSDOH Wadsworth Center for virus testing and sub-typing. All shipping supplies and testing fees are covered by the program.

What do ILINet Providers do?

  • Each week, ILINet providers report to CDC on the total number of patients seen and the number of those patients with ILI by age group.
  • ILINet providers submit patient specimens to the NYSDOH Wadsworth Center Virology Laboratory for virus testing and subtyping. A large portion of the specimens submitted are also tested for antiviral drug resistance.
