Babesiosis is a tickborne disease that can be found worldwide. In the United States, most cases of the disease have been reported in the Northeast and upper Midwest, particularly in parts of New England, New York, New Jersey, Wisconsin and Minnesota. Because many people with babesiosis have mild or no symptoms, it’s difficult for health experts to estimate how many people in this country have been infected.
Babesiosis can range from a mild to a serious or even fatal disease. Those who suffer the most serious cases include the elderly, transplant patients, and those with diseases associated with immunosuppression, such as HIV infection.
