ObjectiveTo investigate epidemiological characteristics and trends of five sexually transmitted diseases （STDs） in Gongshu District of Hangzhou City， and to provide evidence for the development of control strategies.

MethodsData of five STDs from 2012 to 2019 in Gongshu District were collected and then analyzed by descriptive epidemiological methods.

ResultsIn 2012－2019， a total of 9 767 STD cases were reported in Gongshu， with an average incidence rate of 218.35 per 100 000. The overall incidence rate of STD tended to decline over years （χ²=82.60，P<0.001）.The areas with high incidence were mainly Xiangfu sub-district， Shangtang sub-district and Daguan sub-district with a total of 4 136 cases， accounting for 42.34%.The occupations with the highest proportion were business service （35.89%）， worker （19.03%）， household work and unemployment （15.94%）. Latent syphilis was the main stage of syphilis， which increased at an average annual rate of 14.08%. The proportion of primary syphilis and secondary syphilis decreased over years， with the average annual reduction rate of 36.86% and 18.77%， respectively. The average annual incidence of genital chlamydia trachomatis infection in females （100.03 per 100 000） was higher than that in males （31.88 per 100 000）.The average annual incidence of condyloma acuminatum in males （24.68 per 100 000） was higher than that in females （16.80 per 100 000）.The average annual incidence of gonorrhea in males （75.41 per 100 000） was higher than that in females （13.06 per 100 000）.

ConclusionThe incidence of five STDs in Gongshu District is effectively controlled. It warrants health education， behavioral intervention， STD screening， and standardized diagnosis and treatment services for high-risk groups in high-risk areas to control the epidemic of STDs. Gender differences in reported incidence of condyloma acuminatum， gonorrhea and genital chlamydia trachomatis infection may be reduced by strengthening outpatient health education and optimizing laboratory examinations.
