Herpes Gladiatorum
Other Names
- HSV 1
- HSV 2
- Herpes Simplex Virus
- Herpes rugbiorum
- Scrumpox (after rugby football)
- Wrestler's herpes
- Mat pox (after wrestling)
Background
- This page refers to Herpes Gladiatorum (HG), a viral infection causing cutaneous non-genital herpes seen in athletes
- Herpes Genitalia is discussed separately
History
- Originally termed herpes gladiatorum (HG) by Selling and Kibrick in 1964 (need citation)
- Term first widely used when a wrestling camp had 60/175 wrestlers contract the virus, forcing closure of the camp in 1989[1]
Epidemiology
- Virology
- Incidence
Pathophysiology

- General
- Occurs due to cutaneous inoculation with HSV1
- Variable presentation, practitioner unfamiliarity often leads to misdiagnosis
- The face is involved in more than 70% of herpes outbreaks in wrestling
- Outbreaks
- Although up to 30% of high school athletes carry the virus, only 3% are aware[3]
- For this reason, large outbreaks seem to occur for unknown reasons
- Subsequently, there may be lack of proper suspicion when such outbreaks do develop
- Diagnosis
- Often missed by physicians
- One study estimated that the correct diagnosis was made only 10% of the time on initial presentation[7]
Mechanism

- Skin-to-skin contact
- Transmission is almost exclusively from direct skin-to-skin contact.
- Increases risk of traumatic inoculation
- Sports with prolonged skin to skin contact include wrestling, rugby
- Non-contributory
- Training mats and other fomites (need citation)
Virology
- Inoculation[8]
- Transmitted via viral replication in ganglia and spread along sensory nerve tissue
- Multiple dermatomes can be involved, may be bilateral
- There is a 4 to 11 day incubation period
- Prodrome of hyperesthesia and paresthesia follows incubation
- No systemic signs are present at this time
- Rash
- Papulovesicular rash develops within 2 days, appears in clusters
- May coalesce to form plaques with surrounding erythema, edema
- Crusts develop
- Healing begins within 10 days of onset without hyperpigmentation, scarring
- Constitutional symptoms (low-grade fever, chills, malaise, and anorexia, headache, tender regional lymphadenopathy) often accompany primary infection
Associated Conditions
Risk Factors
Differential Diagnosis
- Cellulitis
- Abscess
- Impetigo
- Herpes Gladiatorum
- Herpes Genitalia
- Tinea (Capitis, Barbae, Corporis)
- Hidradenitis suppurativa
- Pediculosis
- Scabies
- Molluscum contagiosum
- Verrucae (Warts)
Clinical Features
- History
- The face is involved more than 70% of the time (wrestling)
- The rest of the body makes up the remaining 30%
- Primary HG
- Typically presents with systemic symptoms (malaise, low-grade fever, sore throat, lymphadenopathy, headache)
- 1-2 days later, 1-2 mm maculopapular vesicles will coalesce with minimally reddened base
- 90% to 93% of infections will occur within 8 days of exposure[2]
- Lesions typically affect dominant hand, side of head of preferred tie position (wrestling)
- Secondary HG
- Fewer vesicles, outbreaks are shorter, fewer systemic symptoms
- Reoccur, in the same dermatomal or peripheral nerve pattern
- Physical Exam
- Inspect oral mucosa for evidence of gingivostomatitis
- Ophthalmologic exam for ocular herpes presenting as acute, follicular conjunctivitis
- Herpetic Sycosis: lesions seen in a beard distribution from autoinoculation while shaving.
Evaluation

Microbiology
- Direct microbiology for HSV 1, HSV 2 recommended
- Examples: Viral culture, HSV polymerase chain reaction
- Culture is often cheaper, PCR is more rapid
- Often confused with other skin infections
- Help distinguish herpes gingivostomatitis and sycosis from other causes of pharyngitis, folliculitis
- Tzank smear is no longer favored due to poor sensitivity, specificity
- Serology
- Limited clinical value due to high rates of positivity, low rates of active disease
- Commonly lags behind clinical infection
- Direct microbiologic testing of active lesions is preferred over serologic testing
Classification
- Not applicable
Management
Treatment
- General treatment principles[11]
- Athletes are treated with oral antivirals, which speeds resolution of symptoms
- Prevents transmission to an exposed opponent
- Antivirals
- Primary Infection
- Valacyclovir: 1000 mg twice daily (or 20 mg/kg 3 times daily for children <20 kg) for 7-10 days
- Recurrent infection
- Valacyclovir: 500 - 1000 mg twice daily for 7 days
- Prophylaxis
- Valacyclovir 500 mg PO daily (if most recent infection >2 years ago)
- Valacyclovir 1 g PO daily (if most recent infection <2 years ago)
- Primary Infection
- Prophylaxis
- Athletes with a history of herpes labialis, herpes genitalia, herpes gladitorum should consider season-long prophylaxis
- Suspend athletic participation
- Athletes must cease all sporting activity when diagnosed and during treatment
- Return to play is decisions should follow established national guidelines
- Antibiotics
- Not indicated unless super imposed infection is suspected
- Note that patients are often treated with antibiotics for a presumed case of folliculitis
Prevention
- Hygiene
- Athletes should shower immediately after practice
- Use their own soap, towels, and razors.
- Towels washed after each use with hot water, detergent
- Skin Hygiene
- Wash hands often
- Do not pick, squeeze skin lesions
- Report any suspicious lesions to coach or athletic trainer
- Equipment
- Practice and competition gear cleaned after each use with soap and water
- Disinfect training mats after use
- Valacyclovir prophylaxis
- Shown to decrease risk of HSV acquisition, prevent recurrence of previous, outbreak
- True in both HSV-seropositive and HSV naïve wrestlers
- At a wrestling camp, daily oral valacyclovir decreased recurrent outbreaks by 89.5%, prevented contraction of the virus[3]
- Recommend starting at least 5 days before the season, camp or tournament
Rehab and Return to Play
Rehabilitation
- Not applicable
Return to Play/ Work
Primary Herpes Zoster Infection
- NCAA Guidelines[12]
- Must have firm, adherent crust at time of participation
- No evidence of secondary bacterial infection
- No new blisters for 72+ hours
- 120+ hours of antiviral therapy
- No systemic symptoms
- May not cover active infections to allow participation
- NFHS[13]
- All lesions scabbed over
- No new lesions for 48+ hours
- 10+ days of antiviral therapy for cutaneous lesions only
- 14+ days of antiviral therapy if systemic symptoms
Secondary Herpes Zoster Infection
- NCAA Guidelines
- Must have firm, adherent crust at time of participation
- No evidence of secondary bacterial infection
- No new blisters for 72+ hours
- 120+ hours of antiviral therapy
- May not cover active infections to allow participation
- NFHS
- All lesions scabbed over
- No new lesions for 48+ hours
- 120+ hours of antiviral therapy
Complications and Prognosis
Prognosis
- With proper treatment, most athletes have an excellent prognosis
Complications
- Herpes keratitis (ocular herpes)
- Conjunctival scarring
- Vision loss
- Recurrence
