[Risk of noscomial infection in intertropical Africa--part 1: background].

Nosocomial infection is a risk in any health care setting. A review of recent medical literature shows that there is a paucity of information on nosocomial infection in intertropical Africa. Often misunderstood or denied, nosocomial infection is in reality an underestimated public health problem at most medical facilities even university hospital centers. However most hospitals are confronted with the same financial, structural and logistics difficulties, with limited training and awareness about hospital hygiene among caregivers, and with situations bringing together contagious infections with susceptible subjects. Assessment of the risks for patients and caregivers is a necessary prerequisite for implementing measures to control nosocomial infections in intertropical Africa.
