Since 1987, the DPH has maintained Lyme disease (LD) surveillance systems to describe the epidemiology of this disease. The graph reflects periods of increasing and decreasing disease transmission potentially due to environmental factors, environmental modifications made around the home, weather, personal protective measures used by people to avoid tick bites, and changes in surveillance methods. In addition, under-reporting by health care providers is common in high endemic areas and where surveillance has been conducted for a long time. Overall, the reported incidence of LD in Connecticut has decreased in recent years.

The DPH works collaboratively with the Centers for Disease Control and Prevention (CDC), Local Health Departments (LHDs), and the Connecticut Agricultural Experiment Station (CAES). All partners have an educational roll for Connecticut residents. The LHDs are generally the first source to educate their residents on Lyme disease (LD) symptoms, risk, and prevention measures. They also have an active role in determining if a tick should be sent for identification and testing. The CAES conducts tick species identification and testing. They also maintain tick species and testing information on their website. The DPH has applied for funding through the CDC that has allowed for LD education and surveillance for the state.

Prevention depends on personal protective measures to avoid tick bites, and environmental modification to reduce ticks in areas where people recreate, especially around homes in wooded areas. To raise awareness of these measures, press releases are distributed during summer months. Information concerning surveillance data and prevention measures are made available online to share with Local Health Departments, health care providers, and the general public. 

Enhance public education programs regarding prevention strategies, including tick avoidance.

Expand health care provider education regarding evidence-based tick-borne disease diagnosis and treatment.

Increase the number of clinical laboratories that report positive Lyme disease test results electronically.

Develop and implement consistent tick reduction strategies statewide.
