Tick-borne Disease

Massachusetts Department of Public Health                                                                                                                                                                          Both 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. Please click here for more information on tick-borne diseases and how to prevent them.
