Quick Answer
Herpes gladiatorum is a herpes simplex infection transmitted skin-to-skin in contact sports, mostly wrestling. It causes painful clustered blisters on the face, neck, shoulders or arms, sometimes with fever and swollen glands. Oral antivirals such as valaciclovir shorten episodes and, taken preventively during a season, reduce recurrences. Athletes must not compete until lesions are fully crusted.
Symptoms
- Clusters of small painful blisters on a red base
- Head, face, neck, shoulders and arms
- Tingling or burning before blisters appear
- Fever, sore throat and swollen glands in the first attack
- Recurrences at the same site, usually milder
Causes & Risk Factors
- Herpes simplex virus type 1
- Direct skin-to-skin contact during wrestling, rugby and martial arts
- Shared mats and equipment (less common)
- Recurrence triggered by stress, illness, sun exposure and trauma
Treatment & Management
- Oral valaciclovir or aciclovir, started as early as possible
- Suppressive antiviral therapy through the competitive season for recurrent cases
- Exclusion from contact until all lesions are crusted and dry
- Covering does not make an athlete safe to compete
- Regular skin checks and mat hygiene in teams
When to See a Doctor
See a doctor at the first sign of blisters if you play contact sport, and urgently if lesions are near the eye, if you develop severe headache or if the eruption is widespread.
Frequently Asked Questions
When can I wrestle again?
Most governing bodies require no new lesions for 72 hours, all lesions firmly crusted, and completion of a defined course of antiviral therapy before return to contact. Covering active lesions is not sufficient.
Will it keep coming back?
The virus remains dormant in nerve tissue and can reactivate, usually more mildly. Daily suppressive antivirals during the season substantially reduce recurrences and transmission risk.
