[Nosocomial infections in geriatric facilities].

Epidemiology: In long term geriatric facilities, the prevalence of nosocomial infections (to the order of 10% in the surveys) is greater than that observed in short-term medical care centers. An endemia of methicillin-resistant Staphylococcus aureus, of between 24 and 57% of hospitalized patients, is noted in many geriatric facilities. In decreasing order, the infections that predominate are: urinary (1/3), lower respiratory tract (1/4) and cutaneous tissue infections (1/5).
