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.
Learn more about EEE and how to protect yourself and your family in this fact sheet about EEE and download the Mosquito-borne Disease Prevention Poster.
Routine mosquito testing results are typically reported mid-June into early October. The Department of Public Health is conducting early season surveillance activities to begin to assess the risk of WNV and EEE in 2022.
