*** Annual gonorrhea screening for at-risk sexually active women, including women with new or multiple sex partners, or women who are living in areas with high rates of disease.
*** Syphilis, HIV, and chlamydia screening for all pregnant women, and gonorrhea screening for at-risk pregnant women starting early in pregnancy, with repeat testing as needed.
** Males
*** At least once-per-year screening for syphilis, chlamydia, gonorrhea, and HIV for all sexually active gay, bisexual, and other men who have sex with men (MSM).
*** Men who have multiple or anonymous partners should be screened more frequently for STIs, at 3- to 6-month intervals. More frequent screening is also recommended for MSM who use illicit drugs, particularly methamphetamine, or whose sex partners use them.
