Abstract
Evidence of human infections in Milwaukee is reviewed to determine if the progressive spread of Q fever in the cattle of the Milwaukee milk shed affect human infections. However, only sporadic clinical cases have been encountered.
A study of 1,106 individuals in various selected population groups showed that 3.4% had complement-fixing antibodies for Q fever.
A review of 2,428 patients with respiratory infections of suspected viral origin between 1955 and 1965 confirmed 29 cases of active or recent infection of Q fever.
Epidemiological studies on 22 of these cases demonstrated that fever of undetermined origin was the predominant syndrome, that the majority were men between the ages of 38 and 55, and that contact with cattle or infected premises was the most significant contributing factor.
