Abstract

With the increasing use of antiretroviral therapy (ART) in developing countries, little is known on the potential impact of large-scale ART use on sexual behavior. We used Herpes simplex virus type 2 (HSV-2) infection as a marker for sexual behavior to aid in assessing the association between ART related knowledge and beliefs and sexual behavior. This cross-sectional study analyzed secondary data collected in Kisumu’s general population. A total of 1,655 participants (749 men, 906 women) aged 15 to 49yrs were interviewed. Socio-demographic factors, prevalence of HSV-2 and ART related knowledge and beliefs and their association with HSV-2 infection were evaluated. Overall, the prevalence of HSV-2 was 53%, and significantly higher in females (65%) than males (38%), p<0.001. Males and females with only primary education, history of drug abuse, who have ever been married and of Luo ethnic community were more likely to have HSV-2 infection. Overall, 17% believed that ART cured HIV/AIDS. Males who believed ART cured HIV had significantly >2 times odds of having HSV-2 (aOR: 2.02, 95% CI: 1.1 to 3.43) similar observations in females (aOR: 2.14, 95% CI: 1.34 to 3.40). Misinformation on ART capability may lead to increased HIV and sexually transmitted infection incidence if people think they are a cure for HIV. Targeted informative messages on ART to those at risk may aid in reducing the incidence of HSV-2.
