Abstract: Objective To analyze the status and epidemiological characteristics of syphilis in Rugao City,provide a basis for scientific prevention and control of syphilis. Methods The data of syphilis cases reported in Rugao City from 2012 to 2021 were analyzed,and the annual change percentage(APC) was used to describe the trend of incidence rate. Results From 2012 to 2021,totally 3 902 syphilis cases were reported in Rugao City,the average annual reported incidence was 27.43/100 000,and the incidence was on the rise(APC=15.94%,P<0.01). The average annual reported incidence of recessive syphilis was 20.49/100 000, the incidence was on the rise(APC=27.75%,P<0.01),and the peak age group of latent syphilis appeared in ≥60 year-old group. The average annual reported incidence of early syphilis was 6.69/100 000, the incidence showed a downward trend(APC=-4.57%,P<0.01).The peak age group of male early syphilis was the 20-<30 age group. Before 2016, the peak age group of female early syphilis was the 20-<30 age group. After 2020, the incidence of female early syphilis in the <20 age group and ≥ 60 age group showed an upward trend. The annual average reported incidence rate of late syphilis was 0.26/100 000, The reported incidence rate had no obvious upward trend(APC=3.00%,P>0.05). For the occupational distribution,the most cases were farmers(61.12%),followed by household and unemployed(22.40%) and retired individuals(7.66%). The cases were mainly reported in the main city and adjacent main urban areas,including Rucheng Street,Chengbei Street and Dongchen Town. There was no obvious change trend in the reported incidence of each region from 2012 to 2015,and reported incidence in Rucheng Street showed an upward trend(APC=-6.86%,P<0.05),while the reported incidence of syphilis in Jiang'an Town was on the rise(APC=10.22%,P<0.05). Conclusions The incidence of syphilis in Rugao City is on the rise,which is dominated by the recessive syphilis,the early syphilis should focus on women aged <20 years old,men aged 20-<30 years old,women aged 40-<50 years old,and people aged ≥60 years old. It is necessary to carry out targeted publicity and intervention measures for sexually transmitted disease prevention and control,and strengthen publicity and intervention for syphilis prevention and control in rural areas.
