Lyme Disease Annual Statistics
The Connecticut Department of Public Health has maintained comprehensive Lyme disease surveillance since 1987. To define the epidemiology of Lyme disease in Connecticut and follow disease trends, surveillance methods were modified and enhanced over time as surveillance goals and resources changed. Surveillance has included passive and active methods that incorporated physician-reporting (1987-present) and laboratory-reporting (1998-2002, 2006-present) components. These data reflect cases meeting the national surveillance case definition for monitoring purposes. Since Lyme disease may be suspected based on broader clinical criteria, these data do not reflect all persons diagnosed or treated.
