Objective To analyze the epidemiological characteristics of syphilis in Fucheng District,Mianyang City from 2015 to 2022,and to provide reference for adjusting the prevention and control of syphilis in this District.Methods Descriptive epidemiological methods were used to analyze the epidemiological characteristics of 2 337 reported cases of syphilis in Fucheng District,Mianyang City from 2015 to 2022.The rates were tested by Chi-square test.The circular distribution was used to calculate the r value.P＜0.05 was considered statistically significant.Results From 2015 to 2022,a total of 2 377 confirmed cases of syphilis were reported in Fucheng District,Mianyang City,with one case of death.The annual average reported incidence rate was 52.46/105,the mortality rate was 0.02/105,and the case fatality rate was 0.04％.There were statistically significant differences in the reported incidence of syphilis in different years(x2=228.422,P＜0.001).The reported incidence rate increased from 39.07/105 in 2015 to 73.15/105 in 2022,showing an upward trend(x2trend=56.313,P＜0.001).The reported incidence rate of syphilis in urban streets was higher than that in rural towns(x2=188.597,P＜0.001).There was no seasonal clustering peak characteristic of reported onset of syphilis(r=0.031,P=0.518).The reported incidence rate of syphilis in women was higher than that in men(x2=27.250,P＜0.001).The reported onset age of syphilis was higher in the age group over 70 years old(135.96/105),and there were statistically significant differences in the reported incidence rate among different age groups(x2=881.971,P＜0.001).The occupations of the reported cases of syphilis were mainly household work and service work(47.79％).Conclusions From 2015 to 2022,the reported incidence rate of syphilis in Fucheng District of Mianyang City increased year by year.The reported incidence rate of syphilis in urban streets was higher than that in rural towns.There was no seasonal clustering peak characteristic of reported syphilis incidence.The reported incidence rate of syphilis in women was higher than that in men.The incidence rate of syphilis was higher in the age group over 70 years old.
