ILINet Providers
An ILINet provider conducts surveillance for Influenza-like illness in collaboration with the Florida Department of Health’s Bureau of Epidemiology and the U.S. Centers for Disease Control and Prevention (CDC).
About ILINet Sentinel Providers
ILINet providers are key to the success of the Florida Department of Health’s Influenza Surveillance System. Data reported by sentinel providers, in combination with other influenza surveillance data, provides a national picture of influenza virus and Influenza-like illness activity in the U.S. and Florida.
Providers of any specialty (e.g., family practice, internal medicine, pediatrics, infectious diseases) in any type of practice (e.g., private practice, public health, clinic, urgent care center, emergency room, university student health center) are eligible to be sentinel providers.
Sentinel Provider Recruitment Packet
Florida clinicians are an important part of the process. The ILINet recruitment packet includes:
- Program
- Summary
- Enrollment Form
- Reporting
- Schedules
- Frequently Asked Questions
ILINet Reporting
ILINet providers report the number of patient visits each week and number of patient visits for ILI by age group (0-4 years, 5-24 years, 25-49 years, 50-64 years, and 65 years or older) year round. These data are reported once a week to a central CDC database through an online platform. Most providers report that it takes less than 30 minutes a week to compile and report their data.
Sentinel providers can submit specimens from a subset of patients to the state laboratory for virus isolation free of charge.
Volunteer
Serious complications due to influenza can also occur in persons with chronic health conditions such as heart disease, diabetes, chronic lung conditions, or HIV.
Data from sentinel providers are critical for monitoring influenza’s impact in Florida. In combination with other influenza surveillance data, they can be used to guide prevention and control activities, vaccine strain selection, and patient care. Sentinel providers receive feedback on the data submitted, and data are summarized and reported along with other flu surveillance mechanisms in the Florida Flu Review.
