Who is affected by genital herpes

Genital herpes is one of the three most prevalent sexually transmitted infections in Canada and one of the most common sexually transmitted infections worldwide.

  • Most genital herpes infections are acquired by the age of 30.1
  • More women than men have genital herpes.
  • In the United States, the greatest increase in genital herpes infection in the past decade has been among teenagers.
  • The risk for transmission from an infected mother to her newborn is highest (30% to 50%) for mothers who have a primary infection but who may not have apparent blisters or sores. If a pregnant woman has recurrent outbreaks, the risk of passing the virus to the baby is reduced to less than 1%.2
