Abstract: 【Abstract】 Objective To investigate epidemiological features and trends of genital herpes in Zhejiang province, and to provide scientific evidence for developing control strategies. Methods Data on reported cases of genital herpes in Zhejiang province between 2011 and 2020 were collected from national notifiable infectious disease surveillance system in China Disease Control and Prevention Information System, and a descriptive epidemiological study was conducted. Results The reported incidence rate of genital herpes in Zhejiang province between 2011 and 2020 ranged from 4.92 per 100 000 to 6.19 per 100 000, without a significant upward or downward trend （trend χ2 = 0.03, P = 0.959）; the reported incidence rate in females showed an increasing trend (from 4.50 per 100 000 to 6.02 per 100 000, trend χ2 = 5.13, P = 0.034）, with an average annual increase rate of 3.27%; among all the age groups, the sexually active population aged 20 - 39 years showed a high reported incidence rate of genital herpes, but the incidence rate increased significantly in the groups aged 15 - 19 years and over 50 years, with the average annual increase rates being 8.10%, 9.24%,7.81% and 4.27% in the groups aged 15 - 19 years, 50 - 54 years, 55 - 59 years and over 60 years respectively. The largest proportion of cases was found in farmers （28.38%, 8 779/30 931）, and high average annual increase rates in proportions were observed in healthcare workers, retirees, students, unemployed population and cadres （13.71%, 13.14%, 10.74%, 9.36% and 7.00%, respectively）. The reported incidence rates were high (over 5 per 100 000) in Eastern coastal areas such as Ningbo, Wenzhou, Taizhou, as well as Jinhua city with relatively developed industrial economies in central Zhejiang; the reported incidence rate markedly increased in Hangzhou city, with an average annual increase rate of 5.39%. Conclusions There was no obvious downward trend in the prevalence of genital herpes in Zhejiang province from 2011 to 2020. Attention should be paid to the prevention and treatment of genital herpes in females, adolescents and the elderly, and the monitoring of herpes simplex virus infections and investigation of infection routes and exposure history should be strengthened.
