摘要：

On December 2006, an outbreak of gastroenteritis occurred at a residential-care facility for the elderly in northern Italy. Thirty-five of 61 individuals interviewed (attack rate, 57.4%) fell ill. In 94.3% of cases, the onset of illness was within 48 h of a Christmas party at the facility. Norovirus (NoV) was detected by RT-PCR in 24 of 31 individuals examined, including three asymptomatic food-handlers, in whom there was evidence of long-lasting excretion of viral particles. The identification of a sequence referring to the '2006a GII. 4 NoV variant' in all examined strains supported the hypothesis of a common point source. This retrospective cohort study is the first report on an outbreak of NoV gastroenteritis in an Italian residential-care facility for the elderly.
