The mean ages in case and control groups were Control measures included a hand-hygiene campaign, deep disinfection of hospital surfaces, strict isolation of cases, use of personal protection equipment, and restriction of antibiotic use.

De las 70 muestras tomadas Full Text Available An outbreak of 14 cases of human immunodeficiency virus HIV infection was discovered by chance in May among hemodialysis patients at a university hospital in Bucaramanga, Colombia.
The outbreak occurred in Stored sera were used to establish the probable period of infection PPI for 10 of the 14 cases. A nested case-control study was carried out to evaluate possible transmission mechanisms. Only invasive dental procedures were significantly associated with the risk of infection. Patients upon whom invasive dental procedures were performed during their PPIs had an average risk of HIV infection 8. None of the dental care personnel were found to be infected. Based on the available evidence, it seems most likely that the infection was transmitted from patient to patient by contaminated dental instruments.
