An Epidemic of Acute Toxoplasmosis

An epidemic of acute lymphadenitic toxoplasmosis involved five medical students. Fever, headache, myalgia, lymphadenopathy, splenomegaly, and extremely high and rising Sabin-Feldman dye test and complement fixation titers characterized the illness. The students all ate rare hamburger at the same place, on the same night, and evidence indicates that this was the way in which the infections were acquired.
