Parallel declines in HIV and hepatitis C virus prevalence, but not in herpes simplex virus type 2 infection: A 10-year, serial cross-sectional study in an inner-city emergency department.

ABSTRACT: BACKGROUND:The Johns Hopkins Hospital Emergency Department (JHHED) has served as an observational window on the HIV epidemic in a socioeconomically depressed, urban population. We previously reported that HIV incidence among JHHED patients is decreasing and that prevalence has declined from 11.4% in 2003-5.6% in 2013. OBJECTIVES:This study sought to observe temporal trends in hepatitis C virus (HCV) and herpes simplex virus type 2 (HSV-2) seroprevalence, which are surrogate markers for parenteral and sexual risk behavior, respectively. STUDY DESIGN:Identity unlinked-serosurveys were conducted over 6-8 weeks in the adult JHHED in 2003, 2007, and 2013. Excess sera from 10,274 patients, previously tested for HIV, were assayed for HSV-2 and HCV antibodies. RESULTS:Overall HCV seroprevalence declined steadily from 22.0% in 2003-13.8% in 2013 (Ptrend<0.01), and was significant by all gender and race strata. Overall HSV-2 prevalence declined from 55.3% in 2003-50.0% in 2013 (Ptrend<0.01), but was non-significant after adjustment for demographics. Among HIV+ individuals<45years of age, there was a significant decrease in the proportion of individuals with HCV co-infection [without HSV-2] (Ptrend=0.02) from 2003 to 2013, however, there was an increase in individuals with HSV-2 co-infection [without HCV] (Ptrend?
