Chlamydia and Other Nongonococcal Infections
Screening for Chlamydia
Because chlamydia is so common and because many infected women have no symptoms, tests to screen for chlamydia are recommended for certain sexually active people. If screening is recommended, it is done even if a person uses condoms consistently. Tests are done using samples taken from the rectum, the urethra, or, if they engaged in oral sex, the throat. Womenare screened annually if they are sexually active and under age 25 or if they are 25 years or older, sexually active, and have one or more of the following risk factors: A previous STI Risky sexual activities (such as having a new sex partner or multiple sex partners, using condoms inconsistently when not in a mutually monogamous relationship, or participating in sex work) A history of incarceration A partner who participates in risky sexual activities or has an STI Pregnant women are screened during their first prenatal visit and again during their 3rd trimester if they are at high risk. Men who have sex with womenare not routinely screened, but screening is available if a person requests it and is often offered to all patients at adolescent clinics, STI clinics, and correctional facilities. Men who have sex with menare screened as follows: If they are sexually active: At least once a year If they are at increased risk (those with HIV infection, multiple sex partners, or a partner who has multiple partners): Every 3 to 6 months Transgender and gender diverse peopleare screened if they are sexually active and on the basis of their sexual practices and anatomy. For example, all people with a cervix who are under age 25 are screened annually. If they are 25 years or older, people with a cervix should be screened annually if at increased risk. Rectal swab screening is done on transgender and gender diverse people based on reported sexual behaviors and exposure.
