Abstract:
Objective To investigate the prevalence and trends of human papillomavirus (HPV)infections in gynecology outpatients in Zhejiang province.Methods Samples of cervical exfoliated cells were collected from gynecology outpatients in 11 sentinel hospitals in Zhejiang Province from January 2011 to December 2013.Twenty one HPV subtypes were detected by flow-through hybridization technique.Chisquare test was performed to analyze the prevalence rates of HPV infections in different years and in different age groups.Results A total of 14 569 patients were enrolled in the study,among whom 3 552 (24.38％)were positive for HPV.HPV-16 (5.77％,840/14 569),HPV-52 (4.71％,686/14 569) and HPV-58 (4.52％,659/14 569) were the most prevalent subtypes.Among all patients,2 244 (15.40％) were infected with a single high-risk subtype,426 (2.92％) were infected with a single low-risk subtype,and 882 (6.05％) were infected with multiple subtypes.The rate of multiple infection was on the rise during 2011 and 2013 (x2 =23.65,P ＜0.01).The positive rates of HPV in patients with 15-24 y age group and ＞54 y age group were 27.91％ (211/756) and 27.73％ (439/1 583) respectively,which were higher than those in other age groups (x2 =18.664,P ＜ 0.01).Conclusion HPV infection is popular in gynecology outpatients in Zhejiang province,especially in patients aged 15-24 y and ＞ 54 y,and a certain proportion of patients are infected with multiple subtypes.
