Ixodes scapularis is a vector for several diseases (Lyme disease, babesiosis, anaplasmosis) and is known as the "deer tick" due to it's habit of parasitizing the white-tailed deer, however ticks acquire the Lyme disease microbes by feeding on infected mice and other small rodents. In New York State, Lyme disease is endemic in Suffolk, Nassau, Westchester, Rockland, Putnam, Orange, Ulster, Dutchess, and Albany counties. As of 1993, the deer tick was found in at least 42 counties across the state.
The following information taken from the Centers for Disease Control's pages on Lyme Disease:
Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans by the bite of infected black-legged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks; laboratory testing is helpful in the later stages of disease. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics. Steps to prevent Lyme disease include using insect repellent, removing ticks promptly, landscaping, and integrated pest management. The ticks that transmit Lyme disease can occasionally transmit other tick-borne diseases as well.
The CDC states that the Erythema migrans (EM) rash occurs within 3 to 30 days after a tick bite " in approximately 70 to 80 percent of infected persons" however the education and advocacy group LymeDisease.org points out that "surveillance cases may reflect a higher percentage of people with a rash than are present in the normal population of people with Lyme disease". Clinical and population based estimates give a lower rate, ranging from 27% to 40% of individuals who are infected with Lyme exhibiting the rash. Individuals who have been bitten by ticks and do not have the Erythema migrans rash may still be infected with Lyme Disease.
Other serious symptoms may occur days to months after the bite including "heart palpitations or an irregular heart beat ( Lyme carditis)", inflammation of the brain and spinal cord, and problems with short term memory. Learn the many early and later symptoms of Lyme Disease at the CDC's ' Signs and Symptoms of Untreated Lyme Disease" page.
The New York State Department of Health page includes information on Lyme disease and other diseases spread by ticks, and suggested repellants. Note that tick identification services are no longer available through the NYS Department of Health.
