Ticks and Lyme Disease

Lyme Disease and other Tick-borne Diseases

The New York State Department of Health (NYSDOH) and local health departments continue to investigate the spread of Lyme disease throughout New York State. Lyme disease is a bacterial infection caused by the bite of an infected deer tick. Untreated, the disease can cause a number of health problems. Patients treated with antibiotics in the early stage of the infection usually recover rapidly and completely. Since Lyme disease first became reportable in 1986, over 95,000 cases have now been confirmed in New York State.

The NYSDOH and local health departments also investigate several other tick-borne diseases, including babesiosis, ehrlichiosis (both human granulocytic anaplasmosis and human monocytic ehrlichiosis) and Rocky Mountain spotted fever. These tick-borne diseases are most frequently found on Long Island and in the lower Hudson Valley region. The number of cases of these diseases is much smaller in comparison to the cases of Lyme disease but their numbers are also increasing.
