Babesiosis is a rare infectious disease caused by single-celled microorganisms (protozoa) belonging to the Babesia family. It is believed that the Babesia protozoa are usually carried and transmitted by ticks (vectors). Babesiosis occurs primarily in animals; however, in rare cases, babesiosis infection may occur in humans. Certain Babesia species are known to cause babesiosis infection in humans (e.g., Babesia microti), and the deer tick is a known vector. Human babesiosis infection may cause fever, chills, headache, nausea, vomiting, and/or muscle aches (myalgia). Symptoms may be mild in otherwise healthy people; in addition, some infected individuals may exhibit no symptoms (asymptomatic). However, a severe form of babesiosis, which may be life-threatening if untreated, may occur in individuals who have had their spleens removed (splenectomized) or who have an impaired immune system. A different form of babesiosis has been reported in Europe that is associated with a more severe expression of symptoms.
