2600% increase in Babesiosis infections over the last 12 years


In the last decade cases of tick-borne Babesiosis infection have expanded exponentially.  New reports released by the CDC on Babesiosis are quantifying this rising threat. The CDC reports indicated that cases of Babesiosis infection have skyrocketed and it is not from more accurate reporting but simply more cases of the infection.

Between 2001 and 2015 430 cases were confirmed in Wisconsin alone, with 96% of cases reported in the early spring to early fall months. 158 of those cases were hospitalized, and 3 of those cases were fatal.

Wisconsin only recently began screening for Babesiosis in 2016 after the infection spread through blood transfusions that were contaminated with parasite. They have become abruptly aware of how dangerous this parasite can really be.

Babesiosis is a parasitic infection that contaminate the red blood cells. Patients infected with Babesiosis commonly develop flu-like symptoms such as fever, chills, sweats, headaches, body aches, nausea and/or fatigue. In sever cases Babesiosis can even cause hemolytic anemia, the destruction of red blood cells that can be fatal. Patients can begin to see symptoms as soon as one week, but in some cases it may take several weeks or months to manifest.
