The reported incidence rate of genital Ct infection increased from 3.16 per 100 000 in 2010 to 25.15 per 100 000 in 2019, with an average annual increasing rate of 25.92% (χ 2 = 836.86, P<0.01). Increasing trends in the reported incidence were observed among males and females, females being higher than males in the year 2010 and 2012. The reported incidence rates increased annually in all age groups between 2010 and 2019, and the average annual rate of increase was highest in the group aged 15-19 years.
