Molecular epidemiology of herpangina in the subcenter of Beijing, China: a surveillance study during 2021-2022
Abstract
In this study, we analyzed the dynamic molecular epidemiology of herpangina based on pharyngeal swabs and demographic data collected from children with herpangina monitored in Tongzhou district in China from January 2021 to December 2022. A total of 1022 herpangina cases were diagnosed. Out of 225 samples collected, 56.4% (127/225) were positive for non-polio enterovirus, with seven genotypes identified: coxsackievirus A4 (CV-A4), CV-A6, CV-A10, CV-A2, CV-A16, CV-B3, and CV-A8. The predominant genotypes associated with herpangina changed during and after the COVID-19 pandemic, with the predominant genotypes being CV-A4 and CV-A6 in 2021 and CV-A10 and CV-A6 in 2022.
