[Pneumococcal infections in military quarters (author's transl)]

A retrospective study on prevalence of pneumococcal in French military recruits of two military districts has been made in 1976 and 1977. Among 185,000 adults, 19 pneumococcal diseases were registered (0,1%). 15 were respiratory infections (10 acute pneumonia). The agent has been isolated of blood (the half) and of others samples : expectoration... (the half). In despite of geographical and climatic differences of two districts, the incidence of pneumococcal pneumonia is the same. The low prevalence of that infection results from the age, selection, and medical surveillance of the population studied.
