Abstract
To determine the frequency of sporadic community-acquired Norovirus (NV) infection in the German-speaking part of Switzerland, an evaluation of gastroenteritis cases seen in physicians' practices between July 2001 and July 2003 was conducted. A total of 699 stool specimens documented to be free of common bacterial pathogens was screened for the presence of NV by RT-PCR. NV was detected in 125 (17.9%) of these specimens. In the seasonal analysis, the highest rate of NV-positive samples (38.3%) was found between January and March 2002. After July 2002, the study was expanded to additionally test for NV in stool samples containing a known bacterial pathogen. Among 132 such specimens, NV was detected in only one. This suggests that NV mixed-infections are playing a marginal role in Switzerland.Entities:
