Abstract
BACKGROUND: Human Papillomavirus (HPV) DNA screening was a crucial element in the fight against cervical cancer and had been adopted in many countries, including China. However, the onset of the COVID-19 pandemic in March 2020 disrupted this program significantly. METHODS: The aim of this study is to investigate the prevalence and distribution of HPV genotypes among the population undergoing cervical cancer screening during the pandemic period. From January 2017 to December 2022, Peking Union Medical College Hospital gathered 45,496 cervical swabs from individuals undergoing cervical cancer screening. These samples were analyzed to detect fifteen high-risk HPV (HR-HPV) DNA types and a combination of two low-risk HPV (LR-HPV) types. RESULTS: The study revealed an overall infection rate of 11.24% (5,114/45,496), with 11.06% (5,032/45,496) of individuals infected with HR-HPV. The number of HPV screening patients and the infection rates of HPV, HR-HPV, LR-HPV, multiple genotype HPV (M-HPV), and single genotype HPV (S-HPV) during the pandemic were lower than those observed before the pandemic. Moreover, the age group with the highest percentage of infected individuals was under 45-49 years, with HPV52, HPV58, HPV16, and HPV51 being the most prevalent genotypes. Notably, HPV66 emerged as the fifth most commonly detected genotype during the pandemic. Additionally, among the eleven age groups examined, women under 25 exhibited the highest detection rate, with HPV52 and HPV16 infection rates exceeding those observed in the pre-pandemic period. CONCLUSIONS: The findings of this study offer significant insights for shaping HPV prevention strategies and enhancing cervical cancer screening initiatives in China following the epidemic.
