										CDC recommends annual chlamydia and gonorrhea screening of**all sexually active women younger than 25 years, as well as older women with risk factors.**Such factors include having new or multiple sex partners, or a sex partner who has a sexually transmitted infection.crib
Chlamydia and gonorrhea are important preventable causes of pelvic inflammatory disease (PID) and infertility. Untreated, about 10-15% of women with chlamydia will develop PID. Chlamydia can also cause fallopian tube infection without any symptoms. PID and “silent” infection in the upper genital tract may cause permanent damage to the fallopian tubes, uterus, and surrounding tissues, which can lead to infertility.
In the United States, an estimated 4 million new chlamydia infections and 1.6 million new cases of gonorrhea infections occurred in 2018 alone.*
Most women infected with chlamydia or gonorrhea have no symptoms.CDC recommends annual chlamydia and gonorrhea screening of**all sexually active women younger than 25 years, as well as older women with risk factors**such as new or multiple sex partners, or a sex partner who has a sexually transmitted infection.Highlights2021 STI Treatment Guidelines

Chlamydia Screening, HEDIS and Managed Care* Chlamydia and gonorrhea are the first and second most commonly reported bacterial sexually transmitted infections in the United States. In 2022, a total of 1,649,716 cases of chlamydia and 648,056 cases of gonorrhea were reported to CDC from 50 states and the District of Columbia. The number of reported cases is lower than the estimated total number because infected people are often unaware of, and do not seek treatment for, their infections and because screening for chlamydia is still not routine in many clinical settings.
