A circular, red rash, like the one pictured, is a common skin problem that many people experience at some point. While it may look alarming at first glance, it’s often related to a treatable condition: ringworm, a fungal skin infection. Despite its name, ringworm has nothing to do with worms. It’s actually caused by fungi that thrive in warm, moist areas of the body. What does this type of rash look like?
The rash typically appears as a round or oval patch with a slightly raised, red border and a lighter or less intense center. It may gradually expand outward, forming a ring-like pattern. The affected area may feel itchy, dry, or slightly scaly. In some cases, several rings may appear, especially if the infection spreads.
Common Causes
The most common cause of this type of rash is tinea corporis (ringworm), a fungal infection transmitted through direct contact. It can be acquired by touching infected skin, sharing personal items such as towels or clothing, or even through pets like cats and dogs. Warm, humid environments also increase the risk, so it is more common in people who sweat a lot or live in tropical climates.
However, not all ring-shaped rashes are fungal. Conditions such as eczema, allergic reactions, or even insect bites can sometimes look similar. That’s why proper identification is important.
How to Treat It
If the rash is caused by a fungal infection, over-the-counter antifungal treatments are usually effective.
Products containing clotrimazole, terbinafine, or miconazole can help eliminate the fungus if applied consistently for 2 to 4 weeks. It’s important to continue treatment even after the rash starts to clear up to prevent a relapse.
Keep the affected area clean and dry, and avoid scratching to reduce irritation and prevent spreading.
Wearing loose, breathable clothing can also help the skin heal faster.
