Genital Tract Shedding of Herpes Simplex Virus Type 2 in Women: Effects of Hormonal Contraception, Bacterial Vaginosis, and Vaginal Group B Streptococcus Colonization

Abstract

The present study identifies hormonal contraceptive use, bacterial vaginosis, and high-density vaginal GBS colonization as risk factors for genital tract shedding of HSV-2 in women. Because hormonal contraceptives are used by millions of women worldwide and because bacterial vaginosis and vaginal GBS colonization are common vaginal conditions, even modest associations with HSV-2 shedding would result in substantial attributable risks for transmission of the virus.
