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.

What The Study Did: In this study including 188 women who were nearly all Hispanic or Black, providing individualized breast cancer risk estimates as a standard component of annual preventive health care was associated with improved use of mammography among the women at high risk. This group’s rate of annual mammography increased from 37% during usual care to 51% following risk assessment.

What The Study Did: This case-control study found that exposure to SARS-CoV-2-positive household members was a risk factor associated with infection among vaccinated health care workers. Household exposure is usually longer and closer than casual exposure or exposure at work and does not include masking or distancing, thus exposing one to a higher infectious dose and being more contagious.
