Hospital-acquired infections
-
People who are admitted to the hospital are at risk of acquiring an infection there. Such infections are called nosocomial infections. In the United States, about 4-5% of people who are hospitalized get a nosocomial infection, and about 75,000 of these people die each year. (See also Problems Due to Hospitalization.)

Organisms that are acquired in hospitals are often resistant to many common antibiotics. The frequent use of antibiotics in hospitals encourages resistant strains to develop.
