Ticks can carry harmful diseases. Ticks are bugs that feed on the blood of mammals, birds, or reptiles. Black-legged (deer) ticks and dog ticks are found throughout Massachusetts and may spread different disease-causing germs when they bite you. The most common tick-borne diseases in Massachusetts are Lyme Disease, Babesiosis, and Anaplasmosis. Other diseases that are more rare, but still occur, are Tularemia, Rocky Mountain spotted fever, Borrelia miyamotoi, and Powassan virus. Tick-borne illnesses can be very severe and taking steps to avoid tick bites is important.

EEE (Eastern Equine Encephalitis)
Eastern equine encephalitis (EEE) is a rare but serious disease caused by a virus. It is spread to people by the bite of an infected mosquito. Only a few cases are reported in the United States each year. Most cases occur in eastern or Gulf Coast states. Although rare, EEE is very serious. Approximately 30% of people with EEE die and many survivors have ongoing neurologic problems.
