Abstract:
Objective To understand the dynamic changes of the pathogen spectrum of viral diarrhea in Southwest China, and to provide a scientific basis for formulating prevention and control measures. Methods A total of 2 262 fecal samples of diarrhea cases were collected from the diarrhea monitoring sites in Yunnan, Sichuan, and Chongqing from January 2017 to December 2019. The detection of rotavirus, norovirus, adenovirus, astrovirus, and sapovirus was performed by real-time PCR, and their epidemiological data were collected. Results The ratio of male to female patients was 1.30:1. The majority of patients were 3 years old and younger, accounting for 52.21%% of all cases. Children living at home accounted for 49.38% of all cases. The detection rate of rotavirus was 10.70%, followed by norovirus at 10.43% and adenovirus at 4.60%. The detection rate of rotavirus was the highest in Yunnan and Chongqing, which were 20.18% and 16.96%, respectively, while the detection rate of norovirus was the highest in Sichuan, which was 13.54%. Conclusion Rotavirus was still the main diarrheal pathogen in Southwest China. High incidence of diarrhea occurred in autumn and winter, with children living at home being the main patients. Measures should be taken to prevent outbreaks caused by norovirus and adenovirus.
