Impetigo is a highly contagious bacterial skin infection that spreads quickly in environments where skin contact is frequent and cuts or abrasions are common. Impetigo is one of the most disruptive skin infections in wrestling programs and youth sports because it spreads quickly, keeps athletes out of competition, and is often mistaken for other conditions until it has already spread.
Unlike athlete's foot, ringworm, and jock itch, impetigo is caused by bacteria, not fungi. That distinction matters because it changes the treatment entirely. Antifungal products do not treat impetigo, and recognizing the difference early is one of the most important things athletes, coaches, and parents can do to stop it from spreading through a team.
What Impetigo Is
Impetigo is a superficial bacterial skin infection most commonly caused by Staphylococcus aureus, Streptococcus pyogenes (group A strep), or a combination of both. It typically affects the skin on the face, nose, mouth, hands, and arms, but it can appear anywhere on the body where bacteria find an entry point. In wrestling and contact sports, mat burns, abrasions, and friction sores create the kind of entry points impetigo bacteria need.
It is most common in children, but it affects people of all ages. In athletic environments, wrestlers and BJJ practitioners of any age are at elevated risk due to the combination of close skin contact, shared equipment, and minor skin trauma that is part of training.
Types of Impetigo
Nonbullous impetigo
The most common form, accounting for the majority of impetigo cases. It typically begins as small red sores or blisters that quickly break open, ooze fluid, and form the distinctive honey-colored or golden-yellow crusts that most people associate with impetigo. The crusts dry on the surface of the skin and the infection spreads as the fluid from the sores contacts surrounding skin or is transferred by touch. It most commonly appears around the nose and mouth in young children, but in athletes it frequently appears on the chin, neck, arms, and areas of the body exposed during contact training.
Bullous impetigo
A less common but distinct form caused almost exclusively by Staphylococcus aureus. Instead of small sores that quickly crust over, bullous impetigo produces larger, fluid-filled blisters that remain intact for longer before breaking open. The fluid inside is clear or cloudy. When the blisters break, they leave a raw, wet surface that may be surrounded by a thin layer of dried skin. This form is more common in infants and young children but does occur in older athletes. It tends to appear on the trunk, legs, and arms rather than the face.
Ecthyma
A deeper form of impetigo that penetrates through the epidermis into the dermis, leaving ulcer-like sores that heal more slowly and may leave scars. It requires medical treatment and is not typically managed without a physician's involvement.
How Impetigo Is Different from Ringworm
In wrestling rooms and gyms, impetigo and ringworm are frequently confused, especially early in the infection when impetigo has not yet developed its characteristic crusting. Both can start as a small, red, irritated patch on exposed skin. The key differences:
- Ringworm tends to form a ring shape with a clearer center as it progresses. Impetigo does not form a ring.
- Impetigo develops fluid-filled sores that break open and crust over with a distinctive honey-colored or golden crust. Ringworm produces scaling and peeling but not the same kind of weeping sores.
- Impetigo spreads faster and more aggressively in most cases.
- Ringworm is caused by fungi and treated with antifungal products. Impetigo is caused by bacteria and treated with antibiotics. Using an antifungal product on impetigo will not help.
When in doubt, see a physician. A trained clinician can typically diagnose impetigo on visual examination, and getting the diagnosis right determines the treatment approach.
Symptoms
Common symptoms of impetigo include:
- Small red sores or blisters on the skin, most often around the nose, mouth, or on exposed areas of the body
- Sores that break open quickly and ooze fluid
- Honey-colored or golden-yellow crusts that form as the sores dry
- Itching around the affected area
- In bullous impetigo, larger fluid-filled blisters that remain intact longer before breaking
- In more severe cases, swollen lymph nodes near the affected area
Impetigo is generally not painful, though the affected area may feel itchy or tender. If significant pain, warmth, or swelling develops around the sores, it may indicate the infection is spreading deeper into the skin, which warrants prompt medical attention.
How Impetigo Spreads
Impetigo is highly contagious. It spreads through:
- Direct contact with sores or crusts. Fluid from impetigo sores and material on the crusts can spread the bacteria and are important sources of transmission. Touching an active sore and then touching another area of skin or another person's skin transfers the bacteria directly.
- Indirect contact through shared items. Towels, clothing, headgear, and other items that contact active sores can transfer the bacteria to other people. Shared headgear in wrestling is a well-documented transmission route.
- Skin breaks as entry points. Impetigo bacteria need a way through the skin barrier to establish an infection. Mat burns, abrasions, cuts, insect bites, acne, eczema, and other minor skin damage provide that entry point. Wrestlers and BJJ athletes get more of these than the general population, which is one reason impetigo spreads so readily in training environments.
- Nasal carriage. Staphylococcus aureus is carried in the nostrils of a significant portion of the population without causing illness. In some cases, impetigo on the face originates from nasal carriage of staph, particularly in children.
Impetigo and Strep Throat: The Bacterial Connection
Impetigo and strep throat are two distinct infections that can share a bacterial cause. Strep throat is caused by Group A Streptococcus, and impetigo can also be caused by Group A Streptococcus. That shared origin creates considerable confusion and generates a lot of questions from athletes, parents, and coaches trying to understand the relationship between the two.
Can impetigo cause strep throat?
Not directly. The bacteria present in an impetigo sore are capable of causing strep throat, but the skin infection itself does not typically spread to the throat. The more relevant concern is that both conditions reflect the presence of Group A Strep in the environment. Anyone in close contact with an infected person is at risk of exposure regardless of which infection that person has, and in a wrestling room or BJJ academy that exposure is sustained and repeated throughout the season.
Can you have strep throat and impetigo at the same time?
Yes. A person can develop infections in both the throat and skin simultaneously if they have been exposed to Group A Streptococcus bacteria that establish infection in both locations. If an athlete has a sudden, severe sore throat alongside skin sores that are crusting with a honey-colored crust, both require medical evaluation. Treatment for one does not automatically resolve the other.
Treatment
Impetigo requires medical evaluation and is typically treated with antibiotics. Antifungal products do not treat bacterial infections, and waiting for impetigo to resolve on its own is not the recommended approach, especially in athletic environments where spread to teammates is a real concern.
Topical antibiotics
Mild, localized impetigo is often treated with a prescription topical antibiotic such as mupirocin (Bactroban) applied directly to the sores. Topical treatment is typically applied two to three times daily for five to ten days. The crusts should be gently removed before applying the antibiotic to allow better penetration to the affected skin.
Oral antibiotics
More widespread impetigo, impetigo that is not responding to topical treatment, or impetigo that may involve MRSA typically requires oral antibiotics. The specific antibiotic prescribed depends on the suspected causative organism. Impetigo caused by methicillin-resistant Staphylococcus aureus (MRSA) requires antibiotics that are effective against resistant strains, which is determined by the prescribing physician based on local resistance patterns and sometimes culture results.
Keep sores clean
Gently washing the affected area with soap and water and removing crusts before antibiotic application helps treatment work more effectively. Cover sores loosely with a bandage where possible to reduce the chance of spreading the infection through contact.
What Defense Soap products can and cannot do
Defense Bar Soap and Defense Shower Gel, built around pharmaceutical-grade tea tree and eucalyptus essential oils, support daily skin hygiene and are part of a consistent cleansing routine. They are not treatments for impetigo and should not be substituted for the antibiotic treatment impetigo requires. Good skin hygiene supports the skin barrier that helps prevent impetigo from establishing in the first place, but once the infection is present, medical treatment is the appropriate response.
Can You Train with Impetigo
No. Impetigo is a disqualifying skin condition in competitive wrestling under both NFHS and NCAA rules. Athletes with active impetigo are not cleared for contact training or competition until the infection is fully treated and a physician certifies that it is no longer contagious.
Under NCAA wrestling guidance, impetigo requires systemic antibiotic therapy for a minimum of 72 hours and no new lesion formation for 48 hours before an athlete can be considered for clearance. Lesions must be covered and non-draining. Specific documentation and physician certification are required. NFHS applies similar standards through its skin lesion evaluation form.
These standards exist for good reason. Impetigo spreads fast in wrestling rooms, and a single athlete training through an active infection can expose multiple teammates in a short period of time. Coaches should inspect athletes before practice when possible and should not allow athletes with suspicious sores to train in contact until cleared by a physician.
How to Help Prevent Impetigo
- Shower immediately after training. Showering after practice or competition helps remove surface bacteria and contaminants from the skin. Defense Bar Soap and Defense Shower Gel support a thorough post-training cleansing routine.
- Keep cuts, abrasions, and mat burns clean and covered. Minor skin breaks are the primary entry point for impetigo bacteria. Clean wounds promptly, cover them with a bandage, and change coverings regularly. A clean, covered wound is a much less accessible target than an open one.
- Do not share towels, headgear, or clothing. Shared items that contact active sores are a documented transmission route. In wrestling programs, headgear hygiene deserves specific attention.
- Report suspicious skin promptly. Athletes should feel comfortable reporting skin concerns to coaches and athletic trainers without fear of unnecessary penalty. A culture of early reporting protects the entire team. Coaches should conduct skin checks before practice when possible.
- Wash training gear after every session. Singlets, headgear covers, and other gear that contacts skin should be laundered after every use. Defense Laundry Booster is a laundry additive that supports fabric hygiene and can be added to your regular wash cycle.
- Clean and disinfect mats consistently. Defense Mat and Surface Cleaner removes organic material from training surfaces. Follow with an EPA-registered disinfectant such as BruTab 6S Disinfectant Tablets or Mueller Whizzer to reduce bacteria on training surfaces. Always use according to label directions.

When to See a Doctor
Suspected impetigo should be evaluated promptly by a physician, especially in athletic settings where spread is a concern. See a doctor promptly if:
- You or your athlete has sores that are weeping, crusting with a honey-colored crust, or spreading across the skin
- An existing skin break such as a mat burn is not healing normally and is developing fluid or crusting
- The infection is spreading or not responding to initial treatment
- There are signs of deeper infection such as pain, significant swelling, warmth, or fever
- An athlete has a sudden severe sore throat alongside skin sores, which may indicate both impetigo and strep throat are present
- Multiple athletes in a program are developing similar skin sores simultaneously
Impetigo in a wrestling room or BJJ gym is a team concern, not just an individual one. If multiple athletes are affected, the training environment and hygiene practices warrant review alongside individual treatment.
Frequently Asked Questions
Can you get strep throat from impetigo?
Strep throat is primarily spread through respiratory droplets rather than through contact with skin sores. However, both infections share a bacterial cause, and in close-contact environments the distinction between transmission routes is less clear. Exposure to Group A Strep through any route represents a risk for susceptible individuals.
Can strep throat cause impetigo?
Having strep throat does not directly cause impetigo. However, a person with strep throat is carrying Group A Streptococcus and can spread it to others who may then develop impetigo if the bacteria find an entry point through a skin break or abrasion.
Is impetigo the same as staph infection?
Impetigo and staph infection overlap but are not the same thing. Impetigo is a superficial skin infection caused by Staphylococcus aureus, Streptococcus pyogenes, or both. Staph infection refers more broadly to any infection caused by Staphylococcus bacteria, which can range from superficial skin infections like impetigo to deeper tissue infections, boils, abscesses, and the serious systemic infection associated with MRSA. Impetigo is a specific type of superficial staph or strep skin infection. It is not the same as the deeper, more serious staph conditions that require more aggressive treatment.
How long does impetigo take to heal?
With appropriate antibiotic treatment, impetigo typically begins to improve within a few days. Most cases resolve within one to two weeks of starting treatment. It is important to complete the full course of prescribed antibiotics even if the sores are visibly improving, as stopping early can allow the infection to persist or return.
Can impetigo heal on its own?
Minor impetigo in otherwise healthy individuals may resolve without treatment, but this is not reliably predictable and is not the recommended approach. Untreated impetigo remains contagious, may spread to other areas of the body, and can worsen. In athletic environments where spread to teammates is a real concern, prompt treatment is important.
Is impetigo caused by poor hygiene?
Not exclusively. Impetigo is a bacterial infection that can affect anyone, including people with good hygiene practices. That said, good hygiene, clean skin, and covered wounds reduce the risk of the bacteria establishing an infection. In dense training environments where skin contact is frequent, hygiene practices matter at both the individual and facility level.
Can impetigo cause scarring?
Typical impetigo, the nonbullous form, generally heals without scarring. Ecthyma, the deeper form of impetigo, can leave scars because it penetrates more deeply into the skin. Picking at sores or removing crusts forcefully can also increase the risk of scarring and may spread the infection.
