Herpes Gladiatorum

Overview

Herpes gladiatorum is a skin infection caused by the herpes simplex virus, usually type 1 — the same virus that causes cold sores around the mouth. The virus gets into the skin through small cuts, grazes or rubbing during close skin-to-skin contact, which is why it is best known among people who do contact sports. It causes a cluster of small, fluid-filled blisters that can appear anywhere but most often on the face, neck, shoulders and arms. It is not the same as genital herpes, although a related virus can occasionally cause it, and it is not a sign that someone has done anything wrong.

It is rare in the general population, but it is one of the most common skin infections among people who take part in contact sports. Outbreaks in sports teams are well recognised, and many sports have rules about skin checks before training and competitions.

Anyone can catch it, but it is most often seen in teenagers and young adults who wrestle or play contact sports such as rugby, judo, mixed martial arts or American football. It can also affect children, and people whose immune system is weaker may get a more troublesome infection.

Symptoms

Common symptoms

• A tingling, itching or burning feeling on a patch of skin before any sores appear
• A group or cluster of small, fluid-filled blisters that quickly become moist sores
• Sores that crust over and heal, usually within one to three weeks
• Flu-like feelings such as tiredness, headache, sore throat or a mild fever
• Tender, swollen glands in the neck or armpits
• Sores most often on the head, face, neck, shoulders, arms or chest — the areas that rub against other people in contact sports

Symptoms in children

• May be more unwell with a fever and general tiredness
• Sores can appear anywhere, including the mouth area, and children may be itchy and irritable
• Watch for blisters near the eye, which need same-day medical care
• Children with eczema can become more unwell because the virus can spread over patches of eczema

Symptoms in older adults

• The infection can look similar, but healing may take a little longer
• People taking medicines that weaken the immune system may have more widespread or slower-healing sores
• Shingles is caused by a different herpes virus and looks different — a doctor can usually tell them apart
• Any new painful rash with blisters in an older adult is worth checking with a doctor

Causes

Main causes

• Infection with herpes simplex virus type 1, the virus that usually causes cold sores around the mouth
• Skin-to-skin contact with an infected person, especially during close-contact sports, when small grazes allow the virus into the skin
• Contact with fluid from blisters or moist sores
• Sometimes spread by sharing items that touch the skin, such as towels, razors or equipment
• Occasionally the virus can be passed on by someone with no visible sores, which is known as silent shedding

Risk factors

• Taking part in contact sports such as wrestling, rugby, judo or mixed martial arts
• Training or competing with a cut, graze or broken skin
• Sharing towels, razors, water bottles, headgear or other kit
• Another skin condition such as eczema, which makes it easier for the virus to spread
• A weakened immune system, for example from certain medical treatments or conditions
• Close contact with someone who has cold sores or active sores

When to see a doctor

See a doctor urgently if:

• Sores near, or in, the eye, or any eye pain, redness or sensitivity to light
• A fever with a very painful rash that is spreading quickly
• Any sign of infection in a newborn baby, or contact between a newborn and someone with sores
• Spreading redness, pus, increasing pain or feeling generally very unwell
• Confusion, a stiff neck or a severe headache with a blistery rash — call your local emergency number

Book a routine appointment if:

• You think you have herpes gladiatorum for the first time and want it confirmed
• You keep getting recurrent outbreaks and want to talk about treatment options
• You want to know when it is safe to go back to training or competing
• You are unsure whether a lump, blister or sore is a skin infection
• You have a weakened immune system and develop new sores

Diagnosis

A doctor can usually suggest the diagnosis by looking at the sores and asking about your symptoms, your sport and your recent contact with people who had similar sores. If there is any doubt — for example if the sores are not typical — a small swab taken from a blister can confirm the virus. You do not normally need any scans or X-rays.

Tests that may be done

• A swab from a fresh blister or moist sore, sent to a laboratory to look for the virus
• A blood test for antibodies in some situations, for example when sores have already healed or when the diagnosis is unclear
• A skin check at competitions or by a team clinician, used in some sports as a screening measure rather than a diagnosis
• Swabs or tests for other skin infections, such as bacterial infections, if the picture is mixed

What to expect at your appointment

The appointment is usually quick and non-invasive. A swab is a soft brush or swab wiped gently over a sore, which may feel a little uncomfortable but not painful. Results usually come back within a few days. Until the sores have fully healed, your doctor may advise you to stay away from contact sport so you do not pass the infection to others.

Treatment

There is no way to clear the virus from the body completely, but the infection can be managed well. Most healthy people get better without any treatment, and medicines can help the sores heal faster and reduce discomfort. Treatment works best when started early — ideally within a day or two of the tingling starting — so it is worth contacting your doctor quickly if you feel an outbreak coming on.

Self-care at home

• Keep the area clean and gently pat it dry rather than rubbing
• Do not squeeze, pick or pop blisters — this spreads the virus and can let bacteria in
• Wash your hands often, especially after touching the sores, and avoid rubbing your eyes
• Use your own towel, flannel, razor and water bottle, and wash towels and bedding on a hot wash
• Wear loose, comfortable clothing so sores are not rubbed
• Try a cool, clean compress to ease soreness and itching
• Ask your pharmacist about over-the-counter pain relief suitable for you
• Rest, drink plenty of fluids and give your body time to recover, especially during the first outbreak
• Stay off the mat, pitch or gym until all sores have crusted and healed, and check with your doctor or team clinician before returning

Medical treatments

If you see a doctor early enough, they may prescribe an antiviral medicine — a drug that slows the virus down. These come as tablets or sometimes as a cream, and they work best when started within the first day or two of symptoms. Some people are given a short course for each outbreak. People who get frequent or particularly troublesome outbreaks may be offered a longer, lower-dose course to reduce how often they happen. If the skin has also become infected with bacteria, your doctor may prescribe an antibiotic. Everyone is different, so your doctor will discuss what is suitable for you, including your general health and any other medicines you take. Antiviral medicines are prescription-only, so always speak to a healthcare professional rather than treating yourself.

When is surgery considered?

Surgery is not used to treat herpes gladiatorum.

Living with this condition

Most people carry on with school, work and life as normal, adjusting only while the sores are active. The main practical steps are keeping the area clean and covered, using your own towel, and staying out of contact sport until everything has healed. Tell your coach, team medic or manager — not to get anyone into trouble, but because teams need to know so they can check others and stop a wider outbreak. Off the field, the virus is only spread by close skin contact, so everyday life with family and friends carries very little risk as long as you avoid touching the sores.

Lifestyle tips

• Take a shower with soap and water after training or competing, and wash your kit and towel afterwards
• Never share towels, razors, exfoliating gloves or water bottles
• Cover any cuts or grazes before sport and check your skin before training
• Keep your skin healthy and moisturised, especially if you have eczema, and treat eczema flares promptly
• Get enough sleep and manage stress, as tiredness and stress can sometimes trigger outbreaks
• Learn your early warning signs — a tingle or itch — so you can act fast and avoid passing it on

Diet and exercise

There is no special diet that cures herpes gladiatorum, and no food that will guarantee fewer outbreaks. Eating a balanced diet, drinking enough fluids and getting regular sleep helps your body recover and supports your immune system. Gentle activity such as walking, swimming in your own pool-time or cycling is fine while you heal, but avoid skin-to-skin contact sports and shared gym equipment until the sores are fully gone. Once you are healed, going back to your normal training is safe and encouraged — talk to your club about their skin-check rules so you know what is expected.

Mental health and emotional wellbeing

It is very common to feel embarrassed, worried or upset after a diagnosis like this, especially if it affects your sport or if people in your team are talking about it. Some people worry about being blamed or being seen as 'dirty', which is unfair — this is a common infection in contact sport, not a comment on anyone's character. These feelings usually settle once the sores heal and you know how to manage things. If you are feeling low, anxious or overwhelmed, it is worth talking to someone you trust, your doctor or a school or team welfare contact. Counselling can help. If you ever have thoughts of harming yourself, please reach out for crisis support straight away — contact your local emergency number or an urgent mental health helpline in your country.

Prevention

You can greatly reduce the risk, although it cannot always be avoided. The key steps are showering with soap after sport, never sharing towels, razors or water bottles, covering cuts and grazes before training, and staying away from contact sport while sores are active. Many clubs and competitions run skin checks before matches — these are there to protect everyone and are worth taking part in. If you have a tingle or itch that you recognise as the start of an outbreak, tell your coach and sit out until you have been checked.

Vaccines

There is currently no vaccine available to prevent herpes simplex infection. Research is ongoing, and your doctor can tell you if anything changes.

Screening programmes

There is no routine screening test for herpes gladiatorum in the general population, and blood tests are not usually recommended for people without symptoms. Instead, many contact sports use visual skin checks before training or competitions, which help spot sores early and reduce spread. If you are unsure about your club's rules, ask your coach or team medic.

Complications

If left untreated

• Bacteria getting into the sores, causing a painful skin infection that may need antibiotics
• Spread of the virus to other parts of the body, such as the fingers or eyes
• Eye infection, which can be serious if not treated quickly and needs same-day medical care
• A more widespread and severe infection in people with eczema
• A more severe or longer illness in people with a weakened immune system
• Recurring outbreaks from time to time, often in the same area
• Passing the infection to teammates or family through close skin contact
• Very rarely, the virus can reach the brain and cause a serious infection — this is why a stiff neck, confusion or severe headache with a blistery rash means calling emergency services

Long-term outlook

The outlook is good. For most healthy people herpes gladiatorum is an uncomfortable but temporary skin infection that heals completely within a few weeks, usually without scarring. Antiviral treatment started early can shorten it. Recurrences can happen, but they tend to be milder, shorter and less frequent over time, and some people never have another outbreak. With sensible precautions and advice from your doctor or team clinician, most people get straight back to their sport.
