Surveillance -- Flu Reporting

The Iowa Influenza Surveillance Network (IISN) is comprised of physicians, hospitals, schools, child care centers, businesses, and long term care facilities who track the occurrence on influenza-like illness and hospitalizations. In addition, the state influenza coordinator tracks influenza-related pediatric deaths (<18 yrs).

Outpatient Influenza-Like Illness Surveillance Network (ILINet)

The Iowa Department of Public Health (IDPH) participates in the U.S. Outpatient Influenza-like Illness Surveillance Network (ILINet), in collaboration with the Centers for Disease Control and Prevention (CDC), state and local health departments, and volunteer sentinel providers across the county. ILINet consists of more than 2,900 surveillance sites in all 50 states, Puerto Rico, the District of Columbia and the U.S. Virgin Islands reporting over 30 million patient visits each year. Data provided by the ILINet providers, in combination with other influenza surveillance data, provide a national picture of influenza virus and ILI activity in the U.S.

School Reporting and Surveillance System

School reporting and surveillance systems:

  • Schools are asked to report absenteeism when 10% or more of the total enrollment is absent on any given day
  • Sentinel schools that participate in the IISN report absence due to illness each week.  If you are a school or school district interested in participating, please contact Andy Weigel at (515) 322-1937 to obtain the password for the web-based survey.   

Hospital Reporting and Surveillance Systems

Hospital reporting and surveillance systems:

Sentinel hospitals that participate in the IISN report influenza-associated hospitalization each week.  If you are a hospital interested in participating, please contact Andy Weigel at (515) 322-1937 to obtain the password for the web-based survey.  

If you are unable to report using the survey tool please contact the Center for Acute Disease Epidemiology at (800)362-2736.
