Any person who has HSV-1 or HSV-2 goes to danger of creating cold sores.

According to the WHO, 68% percent of the global population under age 50 has HSV-1.

Not every person who has the virus will have frequent cold sores. People at most risk of creating persistent cold sores or other problems from the virus might have a weakened immune system. These individuals consist of:

-individuals with HIV
-individuals undergoing radiation treatment
-individuals with extreme burns
-body organ receivers

Having conditions such as dermatitis or psoriasis might also boost a person’s threat of creating frequent cold sores.
