HSV-1 prevalence 47.8 percent in 14- to 49-year-olds
Geraldine McQuillan, Ph.D., from the National Center for Health Statistics in Hyattsville, Md., and colleagues estimated the prevalence of HSV-1 and HSV-2 antibodies among individuals aged 14 to 49 years using data from the 2015 to 2016 National Health and Nutrition Examination Survey.
The researchers found that the prevalence of HSV-1 and HSV-2 was 47.8 and 11.9 percent, respectively, during 2015 to 2016. With age, the prevalence of both HSV-1 and HSV-2 increased. Compared with males, females had higher prevalence of both HSV-1 and HSV-2. Mexican-American individuals had the highest prevalence of HSV-1, and non-Hispanic whites had the lowest prevalence. For HSV-2, prevalence was highest among non-Hispanic blacks and lowest among non-Hispanic Asians. From 1999-2000 to 2015-2016, there was a decrease in the prevalence of both HSV-1 (from 59.4 to 48.1 percent) and HSV-2 (from 18 to 12.1 percent).
"From 1999 through 2016, there was a significant decline in the age-standardized prevalence of HSV-1 and HSV-2," the authors write. "For both virus types, a decrease in prevalence over time was seen in all race and Hispanic-origin subpopulations."
