    "excerpt": "Largest nationally representative study finds 12% of patients positive for bacterial vaginosis are infected with at least one STI, such as chlamydia or gonorrhea SECAUCUS, N.J. , July 30, 2026 /PRNewswire/ -- Women who test positive for bacterial vaginosis (BV) were over three times more likely to also test positive for one or more non-viral sexually transmitted infections (STIs) than women who test negative for BV, according to a new Health Trends® study from Quest Diagnostics (NYSE: DGX ) and Hologic, Inc. In the largest national study of its kind, scientists at Quest and Hologic analyzed deidentified aggregated laboratory data from over 1.5 million women across the United States who received molecular testing from Quest between 2022 and 2024. Over one-third of women tested (38.7%) were positive for BV. Of these, 12% were co-infected with at least one STI. The findings were published in O&G Open , a peer-reviewed companion journal to Obstetrics & Gynecology , the official publication of the American College of Obstetricians and Gynecologists (ACOG). \"BV is one of the most common health problems in women, and yet research in this area of women's healthcare is sadly lacking. Our new analysis provides compelling evidence that women with BV are at significant risk for STIs based on a uniquely large dataset reflecting the nation's heterogenous population,\" said co-author Damian...",
