EMBARGOED FOR RELEASE: 11 A.M. (ET), TUESDAY, SEPTEMBER 14, 2021
Media advisory: To contact the U.S. Preventive Services Task Force, email the Media Coordinator at Newsroom@USPSTF.net or call 301-951-9203. The full report and related articles are linked to this news release.
Bottom Line: The U.S. Preventive Services Task Force (USPSTF) recommends that all sexually active women 24 or younger and women 25 or older at increased risk for infection be screened for chlamydia and gonorrhea. The USPSTF concludes current evidence is insufficient to make a recommendation about screening for these infections in men. Chlamydia and gonorrhea are among the most common sexually transmitted infections in the United States, with approximately 1.8 million cases of chlamydia and more than 600,000 cases of gonorrhea reported to the Centers for Disease Control and Prevention in 2019. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this updated statement is consistent with its 2014 recommendation.

Seroprevalence studies estimate how common it is for people to have SARS-CoV-2–specific antibodies due to natural infection or induced by vaccination.
