What: Extragenital Screening for Gonorrhea and Chlamydia
Where: Rectum and throat
Who: Men who have sex with men (MSM), transgender women, people living with HIV, and people on PrEP who report having receptive anal and/or oral sex
When: At least annually, or every 3 to 6 months as needed based on exposure
Why:  When urine-only screening is performed, up to 90% of rectal gonorrhea and 77% of rectal chlamydia infections remain untreated1. HIV-negative men diagnosed with rectal infections are excellent candidates for PrEP, because they have a high risk of HIV infection
How:  Swab specimen (self or clinician-collected swab)

The California Prevention Training Center supports clinics and providers in implementing rectal and pharyngeal STI screening.
