Epidemiological characteristics and control strategies of syphilis in Zhushan County of Hubei Province from 2016-2022
Objective To understand the epidemic characteristics of syphilis in Zhushan County,Shiyan City,and provide a basis for formulating prevention and control strategies.Methods The data of syphilis epidemic in Zhushan County from 2016 to 2022 was derived from the communicable disease surveillance system and the data were analyzed.Results A total of 429 cases of syphilis were reported in Zhushan County from 2016 to 2022,with an average annual reported incidence rate of 13.45/100 000,showing an upward trend year by year.The epidemic situation was distributed in every township of the county,but the highest prevalence was in Pankou Township,Shangyong Township,Chengguan Chamdo and Shuangtai Township.The clinical classification showed that 94.64％of the cases were invisible syphilis,and 80.65％of the cases were caused by non-marital sexual contact.The main occupations were peasants(56.18％)and housework and unemployment(29.60％).It was significantly higher in women than in men(x2=29.78,P＜0.01),but it was significantly higher in men aged 55-＜75 than in women(x2=8.55,P＜0.01).The age of onset was mainly concentrated in the age group of 25-＜60 years old,accounting for 73.66％of the total reported incidence.The reported incidence rates of 75-＜85 years old and 25-＜45 years old were 23.67/100 000 and 23.30/100 000,respectively,which were significantly higher than the average level,and the trend of incidence aging and younger women were obvious.Conclusion From 2016 to 2022,the incidence rate of syphilis in Zhushan County shows a rising trend year by year,the epidemic situation is distributed in every township of the county,the reason for the rise of the epidemic situation is the large number of local migrant workers,the poor accessibility of high-risk behavior intervention,and the high rate of reproductive tract infection among rural women.A sound prevention and control system,standardized prevention and control responsibilities,and precise prevention and control strategies that are in line with local characteristics,such as reminders and warnings for syphilis prevention and control for migrant workers,are important measures to curb the spread of the epidemic.
