[Endemic and epidemic. Investigation of a nosocomial outbreak].

Abstract

The majority of healthcare associated infections are endemic, but outbreaks or epidemic infections also occur. The most frequent nosocomial endemic infections are catheter associated bacteremia, ventilator-associated pneumonia, surgical site infections and urinary catheter associated infections. These are conditions with a significant healthcare burden. Infection control measures are the mainstay for reducing their frequency and health impact. Other nosocomial infections occur in epidemic outbreaks, with potential and various negative consequences. A well conducted outbreak investigation can achieve good control at an early stage of the development of an outbreak. This research is divided into several stages that facilitate monitoring the development of the work in an orderly and efficiently manner. It also includes some guidelines for writing reports and scientific papers concerning outbreaks.
