Abstract:
Objective To investigate the epidemiological characteristics of viral diarrhea in children under 5 years old during 2015-2018 in Xicheng District of Beijing, and to provide evidence for prevention and control of viral diarrhea. Methods Fecal specimens from patients under 5 years old were collected from the outpatient clinic of the Children's Diarrhea Surveillance Sentinel Hospital in Xicheng District, Beijing from 2015 to 2018. Real-time fluorescence PCR was used to detect group A rotavirus (RVA), norovirus (NV), and adenovirus (AdV), Astrovirus (AstV). Results A total of 972 fecal specimens were collected, 142 were tested positive for RVA (14.61%), 136 were tested positive for NV (13.99%), 67 were tested positive for AdV (6.89%), and 49 were tested positive for AstV (5.04%). Mix-infection was found in 46 cases, which accounted for 4.73%. The detection rates of the 4 viruses in children under 2 years old were 80.28%, 77.94%, 83.58%, and 87.75%, respectively. Conclusion Rotavirus and norovirus were the main pathogens of viral diarrhea in children in Beijing Xicheng District from 2015-2018, and iinfants under 2 years old were the high-risk group.
