Lyme Diseases

Lyme disease is an important health concern in Connecticut. Since it was first recognized in the Lyme, Connecticut area in 1975, the Department of Public Health (DPH) has contributed to the understanding of this complex disease, as well as other tick-borne diseases. The reported incidence, which sets the trend for Lyme disease over time, is due to many changing factors that include:

  1. Weather
  2. Tick abundance, habitat, and infectivity rates
  3. Deer population and habitat
  4. Recognition of the disease by those infected and health care practitioners
  5. Living in a wooded area
  6. Potential for contact with ticks, including recreational activities
  7. Disease reporting by the healthcare provider
