Prevalence of sexually transmitted infections and bacterial vaginosis among women in sub-Saharan Africa: An individual participant data meta-analysis of 18 HIV prevention studies
Estimates of sexually transmitted infection (STI) prevalence are essential for efforts to prevent and control STIs. This study used a two-stage meta-analysis to estimate the prevalence of chlamydia, gonorrhea, trichomoniasis, syphilis, herpes simplex virus type 2 (HSV-2) and bacterial vaginosis (BV) among women in sub-Saharan Africa. These findings highlight important features of STI and BV epidemiology. The authors state this methodology can be used where routine STI surveillance is limited and offers a new approach to obtaining critical information on STI and BV prevalence in low- and middle-income countries.
