Objective To investigate epidemiological features of female genital chlamydia trachomatis(CT)infection in Beijing,so as to provide scientific basis for formulating control strategies.Methods The data of the cases with CT infection in Beijing were collected from the disease surveillance information reporting system over a period from 2015 to 2019 and analyzed with descriptive epidemiological method.Results The reported incidence rate of female genital CT infection increased from 6.24 per 100000 in 2015 to 15.11 per 100000 in 2019,with an average annual increasing rate of 24.73%.During the period from 2015 to 2019,84.14%of all reported cases were women in age grades of 20~49 years old.The highest incidence of genital CT infection was found in the 30~year-old age group from 2015 to 2018 and that was found in the 20~year-old age group in 2019.The reported incidence rates increased yearly in all age goups during the period from 2015 to 2019,and the average annual rate of increase in the 20~year-old age group was highest(63.93%),followed by the 15~year-old age group(43.08%).The hightest proportion(69.00%)of the cases were reported from general hospitals,the proportion of the cases reported from maternal and child health institutions increased from 8.89%in 2015 to 17.20%in 2019(χ^(2)=29.94,P<0.05).Conclusion The reported incidence rate of female genital CT infection shows an increasing trend,and the rapid increase in the incidence rate is found among those women aged 15~24 years.More attention should be paid on sexual and reproductive health education for adolescents and young adults.Epidemic of genital CT infection should be concerned,and its surveillance level need to be improved.
