What Is Jock Itch?
Jock itch (tinea cruris) is a contagious fungal infection that affects the skin in the groin area, upper thighs and buttocks. It's caused by a certain kind of fungus that loves warm, moist conditions.
Here's what you need to know about jock itch:
- Jock itch affects areas of the groin, upper thighs and buttocks.
- Jock itch occurs more often in men than women.
- Jock itch typically appears as raised, scaly patches on the skin that itch. Skin may also blister or ooze, although symptoms can vary.
- Jock itch can be cured in 1 week* with LamisilAT products.
How Do You Get Jock Itch?
You can get jock itch by touching someone's infected skin or contaminated surfaces such as towels or bedsheets. The jock itch fungus is spread by spores that can survive by eating the dead skin cells on objects for a long time.
The fungus that causes jock itch prefers warm, moist places such as the groin, upper thighs and buttocks. Moisture is trapped between the folds of the skin, creating the perfect environment for jock itch to grow and spread.
Jock itch is contagious and the fungus spreads easily by contact. If you scratch your athlete’s foot and then touch your groin, the fungus may be transferred and cause jock itch.
What Causes Jock Itch?
Jock itch (tinea cruris) is caused by dermatophytes — the same mold-like fungus that causes athlete’s foot. The fungus often lives harmlessly on human skin, feeding on the keratin of dead skin cells. Its growth is limited on dry, clean skin but in moist and warm conditions the fungus can multiply rapidly. Penetrating the skin through small splits, cracks or wounds, the fungus can infect the top layer of your skin, causing a scaly red rash that may itch and burn. In the groin area, this is known as jock itch.
Jock itch is a common problem for people who sweat heavily — such as those who exercise a lot — but anyone can get it. Even though women can get jock itch, it’s more common among men as moisture is more easily trapped between the scrotum and thigh.
People with diabetes and weakened immune systems are more susceptible to jock itch. Obese people may also be more at risk as their skin folds can trap moisture and allow the fungus to thrive.
The fungus that causes jock itch is contagious and is easily spread between people — though not everyone will go on to develop jock itch. Skin-to-skin contact can spread the fungus from person-to-person or from the groin area to other body parts.
