April 22, 2026 -- The presence of Eastern Equine Encephalitis (EEE) was detected in Lackawanna County in 2024. No human cases were reported locally.

EEE is a viral disease spread by mosquitoes common to Northeast Pennsylvania. Infected people may demonstrate flu-like symptoms, with advanced cases progressing to meningitis or encephalitis. Children and seniors are most susceptible, as well as adults with a compromised immune system. EEE is not contagious from human to human.

EEE is particularly lethal in horses, but vaccination has proven to be highly effective in preventing infection. Vaccines should be administered in coordination with a qualified veterinarian before adult mosquitos emerge. Horses should be brought indoors before dusk to limit risk. Standing water in the immediate area should be mitigated to reduce a mosquito breeding habitat.

Residents are encouraged to reduce mosquito habitat by eliminating standing water around the home. Water in birdbaths should be changed on a weekly basis. Rain gutters should be clear of debris and free flowing. Containers around the property should be stored covered or upside down, and swimming pools should be cleaned and chlorinated once weather permits.

There is no specific treatment to prevent or cure human contraction of EEE. Please seek medical attention if you think you may have been exposed. While rare, human EEE cases that progress to the encephalitis or meningitis stage can be fatal.
