Babesiosis is a tickborne disease caused by a protozoa. In New England, the incidence of babesiosis has increased dramatically over the past ten years. In severe cases, babesiosis can be life-threatening.
I was delighted to recently read an article in the New England Journal of Medicine about babesiosis, written by my friend Ann Woolley, and co-authors. Babesiosis is characterized by nonimmune hemolytic anemia that resolves with antimicrobial treatment and clearance of parasitemia.Ann and her co-authors documented post-babesiosis warm autoimmune hemolytic anemia in patients who did not have a history of autoimmunity. Patients who were asplenic appeared to be at high risk.
Check out the CDC website to learn more about how to avoid getting bit by the tick which transmits babesia.
Felice Freyer also wrote an interesting article in the Boston Globe yesterday about tick-borne illness.
