Answer

Seroprevalence: Antibodies to HSV-1 increase with age starting in childhood and correlate with socioeconomic status, race, and cultural group. By age 30 years, 50% of individuals in a high socioeconomic status and 80% in a lower socioeconomic status are seropositive. Antibodies to HSV-2 begin to emerge at puberty, correlating with the degree of sexual activity. The lifetime seroprevalence can be 20%-80%. [4] More than 90% of adults have antibodies to HSV-1 by the fifth decade of life. [1] ​A slight crossover of immunity occurs between HSV-1 and HSV-2, allowing for milder subsequent infection by the partner virus type.
