Mosquito-borne Diseases

Learn how to protect yourself from illness.

West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE or “Triple E”) are viruses that occur in Massachusetts and can cause illness ranging from a mild fever to more serious disease like encephalitis or meningitis. There are other diseases spread by mosquitoes that people may be exposed to when traveling in other regions of the world. These include Zika virus, Dengue fever, and Chikungunya. Learn how to protect yourself from illness by doing simple things: using insect repellents; wearing long-sleeved clothing; scheduling outdoor activities to avoid the hours around dawn and dusk during peak mosquito season; repairing damaged window and door screens; and removing standing water from the areas around your home.
