This month's report


Highlights from the report:

  • Tick activity and tick-borne diseases like Lyme disease, anaplasmosis, babesiosis, Borrelia miyamotoi and Powassan virus, occur year-round in Massachusetts.
  • Although tick activity is weather dependent, there are two peaks during the year; the first begins in March/April and lasts through August, and the second occurs in October-November.
  • The majority of cases of tick-borne disease occur in June through August.
  • Tick-borne diseases are most frequently diagnosed in children and older adults.
  • Although not every tick is carrying a disease, it is important to take steps to avoid all tick bites.
  • Tick-borne disease prevention includes the use of repellents that contain an EPA-registered active ingredient like permethrin or DEET, wearing light colored clothing to more easily spot ticks, doing daily tick checks and promptly and properly removing any attached ticks.
