Overview
Overview
Worldwide, the incidence of chlamydia is estimated to be 131 million cases per year.[1] In 2014, the incidence of chlamydia was estimated to be 439 cases per 100,000 individuals in the United States.[2] The incidence of chlamydia in women has increased greatly between 1987 and 2003, from 79 to 467 cases per 100,000 individuals.[3] Almost two-thirds of new chlamydia infections occur among youth aged 15-24 years. It is estimated that 1 in 20 sexually active young women aged 14-24 years has chlamydia.[2] Females are more commonly affected with chlamydia infection than males. The female to male ratio is approximately 1.52 to 1.[4] The prevalence of chlamydia among non-Hispanic African Americans is 6.7 times the prevalence among non-Hispanic Whites.[2]
