ABSTRACT

Objective To investigate the epidemiological and pathogenic characteristics of viral diarrhea in Minhang District of Shanghai.Methods Random sampling on diarrhea was conducted in intestinal outpatient departments of 2 sentinel hospitals according to a certain sampling interval in Minhang District from 2014 to 2016.Real-time PCR was used to detect rotavirus (RV),norovirus (NV),adenovirus (AD),astrovirus (AstV) and sapovirus (SaV) in fecal samples.Results A total of 11 243 cases of diarrhea were monitored in 2 sentinel hospitals during 2014 and 2016,with 3 213,3 600 and 4 430 cases for each year,respectively.Out of 809 stool specimens,309 were tested positively,and the positive rate was 38.48％.All 5 pathogenic viruses were detected,mostly NV (207 cases,66.99％)followed by RV (77 cases,24.92％).Conclusions NV accounted for the majority of reported infection diarrhea cases in Minhang District of Shanghai from 2014 to 2016,with significant seasonal peaks.Tailored prevention and control measures should be carried out,particularly in risk seasons.
