Learn about EEE
Eastern equine encephalitis (EEE) is a rare but serious disease caused by a virus that can affect people of all ages. EEE is generally spread to humans through the bite of a mosquito infected with the virus. EEE can cause severe illness and possibly lead to death in any age group; however, people under age 15 are at particular risk. EEE does not occur every year, but based on mosquito sampling, a high risk of occurrence of human cases currently exists.
Routine mosquito testing is typically reported June-October. The Department of Public Health will conduct early season surveillance activities to assess the risk of WNV and EEE in 2021.
