Objective To analyse the epidemiological characteristics of Chlamydia trachomatis infection in Jinan city from 2011 to 2022,so as to provide a basis for improving prevention and control strategies.Methods Data on cases of Chlamydia trachomatis infection were collected from the China Disease Prevention and Control Information System dur-ing 2011 to 2022.Descriptive analysis was performed on the time,population,and geographical distribution of cases,and the incidence was calculated.The annual percentage change(APC),average annual percentage change(AAPC),and monthly percentage change(MPC)were used to analyze the trend of disease occurrence.Results A total of 1 841 cases of Chlamydia trachomatis infection were reported in Jinan city from 2011 to 2022,with an average annual incidence of 1.99/105.The incidence showed an increasing trend from 2014 to 2022,with an APC of 23.18％(P＜0.05).There was a certain seasonality in the occurrence of the disease,with the highest number of cases occurring in June.The average an-nual incidence in males was 2.12/10,which was higher than that in females(1.85/105)(x2=8.21,P＜0.05).The age group with the highest incidence was 21-40 years old,accounting for 76.81％of the cases;housework and unemployment were the most common occupations,accounting for 37.59％of the cases;and the average annual incidence rate in the cen-tral urban area was 3.11/105,which was higher than that in surrounding districts and counties(0.82/105)(x2=611.89,P＜0.05).Conclusion Chlamydia trachomatis infection in the reproductive tract in Jinan city is at a low prevalence level during 2011 to 2022,but there has been an increasing trend in recent years.It is necessary to closely monitor the epi-demiological characteristics of key populations and regional differences to improve the detection rate of infected individu-als.
