Objective: To investigate the prevalence and influencing factors of infection among children with diarrhea under five years of age in Guangzhou City.

Methods: Children with diarrhea under 5 years of age admitted to Guangzhou Children's hospital, Guangzhou Maternity and Child Healthcare Hospital and Guangzhou Women and Children's Medical Center during the period between January 1 and December 31, 2020, were enrolled. Participants' demographics, living environments and health status were collected using questionnaire surveys. Stool samples were collected from participants and nucleic acid was extracted. infection was identified using PCR assay and sequence alignment, and the factors affecting infection among children with diarrhea under 5 years of age were identified using univariate analysis and multivariate logistic regression analysis.

Results: A total of 684 children with diarrhea under 5 years of age were enrolled, including 468 male children and 216 female children, with a mean age of (1.79 ± 1.12) years. The overall prevalence of infection was 4.97% [34/684, 95% confidential interval (3.59%, 6.86%)] among participants, and there was no significant difference in the prevalence of infection between children with chronic [7.52% (20/266), 95% (4.92%, 11.33%)] and acute diarrhea [3.35% (14/418), 95% (2.01%, 5.54%)] (χ = 5.983, = 0.014). Multivariate logistic regression analysis identified keeping pet [odds ratio () = 6.298, 95% (2.711, 14.633)], drinking non-tap water [ = 4.522, 95% (1.769, 11.561)], lactose intolerance [ = 4.221, 95% : (1.043, 17.087)], antibiotic use [ = 0.125, 95% : (0.017, 0.944)] and chronic diarrhea [ = 2.172, 95% : (1.018, 4.637)] as factors affecting infection among children with diarrhea under 5 years of age in Guangzhou City.

Conclusions: infections is detected in children with diarrhea under five years of age in Guangzhou City. Improving home environments and pet-keeping hygiene is recommended to reduce the likelihood of infection among children.
