Does one get herpes if they are stupid enough to wear swim suit of a person that might have had over the underwear course?

Wearing a swimsuit that someone else has worn, even if they have over the underwear, does not increase your risk of contracting herpes. Herpes is a sexually transmitted infection (STI) that is spread through direct contact with an infected person's sores, fluids, or skin. It is not transmitted through clothing or inanimate objects.
