Where is Lyme disease most prevalent?
A. See map on Lyme Disease page. Generally, most Lyme disease is endemic in the northeastern and upper midwest states. There is also Lyme Disease in Europe too, this is not just a disease in the United States. The deer that carry the deer-tick are also in other countries. The vast majority of cases of Lyme disease occur in New York, Connecticut, Pennsylvania, and New Jersey. Other states where the disease is prevalent include Massachusetts, Wisconsin, Rhode Island, Maryland, Minnesota, and Delaware. The prevalence of Lyme disease in the northeast regions of the United States is due to the presence of large numbers of the deer ticks’ preferred hosts, which include white-footed mice and deer and their close proximity to humans. Persons in endemic areas who are frequent visitors to grassy, wooded locations inhabited by white-tailed deer and mice in the Northeast and upper Midwest states and along the Northern Pacific coast of California, are at greatest risk for getting Lyme disease.
