Who's At Risk
HSV infections occur in people of all races, of all ages, and of both sexes.

Increasing age is associated with increased likelihood of infection. Up to 80% of Americans are infected with HSV-1 by the time they are 30 years old.

Only 20% of people who are infected with HSV actually develop visible blisters or sores. That means that approximately 80% of people with HSV infections have not been diagnosed and are unaware of their condition. Nevertheless, they can still transmit the infection to others.
