Babesiosis Study 2018

What is Babesiosis?

Babesiosis is caused by a tiny parasite called Babesia that infects red blood cells. The parasite is spread from animals to humans via a bite from an infected tick. Most people with Babesiosis do not feel sick and do not even remember being bitten by a tick. Some people may have mild flu-like symptoms and recover completely. However, Babesiosis can be a severe and life-threatening infection for hospitalized patients who need a blood transfusion.
