Jock Itch in Children: Causes, Treatment, and Prevention

When a child develops a red, ring-shaped rash in the groin, inner thighs, or buttocks, it’s often jock itch, a fungal skin infection caused by dermatophytes that thrive in warm, damp areas. Also known as tinea cruris, it’s not limited to athletes—it can affect any child who sweats heavily, wears tight clothes, or shares towels or gym equipment. Unlike adult cases, jock itch in children often starts after a diaper rash, swimming, or playing in humid environments where moisture lingers on the skin.

This infection doesn’t just cause discomfort—it can spread. The same fungus that causes jock itch is the same one behind athlete’s foot, a fungal infection between the toes that easily transfers to the groin. Kids who scratch their feet and then touch their groin can accidentally spread it. It can also come from shared towels, gym mats, or even pets with ringworm. The rash looks like a raised, scaly border with clearer skin in the middle, and it itches badly. Kids may complain of burning or stinging, especially after sweating or bathing.

Most cases are mild and clear up with over-the-counter antifungal creams like clotrimazole or terbinafine. But if the rash doesn’t improve in two weeks, spreads to other areas, or gets worse with red streaks or pus, it might be something else—like a bacterial infection or eczema. That’s when you need a doctor. Prescription-strength creams or oral antifungals might be needed, especially if the child has a weakened immune system or recurring infections.

Prevention is simpler than treatment. Keep the groin area dry. After swimming or sweating, change out of wet clothes immediately. Use cotton underwear that breathes. Avoid tight-fitting pants or synthetic fabrics. Don’t share towels, socks, or gym gear. If your child has athlete’s foot, treat it fast—don’t let the fungus have a chance to move up. Apply antifungal powder daily in hot weather, especially if they’re active in sports.

Parents often confuse jock itch with diaper rash or heat rash. But diaper rash usually stays in the diaper area and looks more irritated and bright red, while jock itch spreads outward from the crease of the thigh. Heat rash is tiny bumps that itch less and fade when the skin cools. Getting the right diagnosis matters because using the wrong cream can make it worse.
