3.1 Prevalence of RVA infections in children
During the study period, a total of 1482 stool samples from outpatient children diagnosed with AGE were included in our study, of which 875 were boys and 607 were girls. Overall, 16.6% (246/1482) of children were infected with RVA. A slightly higher detection rate was observed in 2022 (14.5%, 77/531) compared to 2020 (9.7%, 22/226), but without statistical significance (p =0.078). In contrast, the detection rate of RVA was significantly higher in 2021 (20.3%, 147/725) compared to that in 2020 and 2022 (p =0.000). Furthermore, a similar frequency of RVA was observed in both males (16.6%, 145/875) and females (16.6%, 101/607) (p =1.000).
