The most common viral infection seen in athletics. Commonly called a fever blister or cold sore. The virus is carried inactive by a majority of the population and does not erupt until a person's resistance is lowered by another condition such as stress, fever, fatigue or dietary problems. Initially appears as blisters which rupture and form a crusted surface. The condition is usually self limiting and disappears in one to two weeks.
Transmission usually occurs from skin to skin contact or through shared equipment.
Contact should be avoided until the crusted area is gone. The period of maximum contagious spread is five days after onset of eruptions. There is no cure presently available for herpes simplex. Clean all mats and wall mats daily with a disinfectant cleaner. Athletic directors and coaches are advised to contact the company servicing their school for information about products designed to disinfect surfaces.
