The Health Department tracks influenza-like-illness (ILI) in the community as an indicator of the current influenza season. Health care providers provide weekly information voluntarily on how many patients they have seen with ILI, which is defined as having a fever of 100°F (37.8°C) or greater, oral or equivalent, and a cough or sore throat.
