Definition


The term nosocomial disease refers to any disease caught during a stay in a health care facility and suspected to have been acquired in this facility. The causes of the disease are usually infectious, and side-effects of bacteria or an infectious virus spread by another patient at the hospital. But contamination may also be spread by a person who frequents the hospital (nursing staff, visitor), or by improperly sterilized medical equipment. It is considered a nosocomial infection if it appears at least after 48 hours after hospitalization. This period is 30 days long if the infection occurs at the area operated on during surgery, and a year when installing equipment, such as orthopedic prosthesis, cardiac valve stent ... Although important hygiene measures are implemented, nosocomial infections are common in France.
