Use this information to anwer the question: Babesia microti is a red cell parasite that is endemic in the Northeastern and upper Midwestern regions of the US and responsible for the disease referred to as babesiosis. The parasite is most often transmitted by the bite of a deer tick but may also be transmitted by blood. Infection may be asymptomatic or cause non-specific symptoms: fever, fatigue, headache and muscle pain, or in some cases severe disease in those with a compromised immune system, hemoglobin-related diseases (such as sickle cell disease) or those lacking a spleen. The Red Cross began blood donation screening under an investigational protocol in June 2012 in the New England area and upper Midwest. Donors who consented for investigational screening were tested by two tests: an individual donation NAT assay (polymerase chain reaction, PCR) and an antibody assay, the latter using an automated indirect immunofluorescence assay (IFA). Reactive donations were further tested by…
