Transfusion Related Babesiosis in a Non-endemic Region (Western New York)

Babesiosis, an emerging tick-borne zoonosis caused by parasites of the genus Babesia, is typically transmitted via the black-legged tick. Occasionally, can also be transmitted through red blood cell transfusion. In this report, we present a case of babesiosis resulting from a red blood cell transfusion in an area where the pathogen is not endemic. The patient presented with a high-grade fever and hemolytic anemia. This case underscores the critical importance of recognizing Babesia as a cause of hemolysis and emphasizes the necessity of implementing universal screening of blood products for Babesia. Enhanced vigilance in blood safety protocols is imperative to prevent transfusion-associated babesiosis.
