A prevalence survey of nosocomial and community infections in a children's hospital was carried out in the wards of the Bambino Gesù Hospital, Rome, Italy. The overall prevalence of hospital-acquired infection (HAI) was 5.1%, with higher rates in surgical units and among children aged 1 to 5 years. The proportion of community-acquired infections was 9.2%, with higher rates in the infectious disease and internal medicine units and among children aged 6 to 11 years. The most frequent type of HAI was respiratory tract infection, with only a small number of urinary tract infections.

A study was undertaken to determine the relative importance of some sources, routes of transmission, and measures to prevent bacteria entering the wound during biliary tract surgery. When bacteria were growing in the bile they accounted for the majority (greater than 99%) of the bacteria found in the wound. However, when the bile was sterile the skin bacteria at the incision site were found to make a substantial contribution to the wound flora. ⋯ No transfer of skin bacteria from the surgical team through perforated gloves or by direct contact from the surface of operating gowns was demonstrated. Ten of the patients studied had septic wounds. Five of these were infected by bacteria from the bile.
