 The Maine Center for Disease Control reports cases of Lyme disease in the state continue to increase, especially in adults 65 and older. In 2022, about 1,000 Lyme cases out of more than 2,600 reported were in that age group. Dr. Steve Rich, director of the New England Regional Center of Vector-Borne Diseases, says people in that age category of weaker immune systems may get exposed to ticks due to being active in tick-prone areas.
