What Is It?
Tinea corporis, commonly called ringworm, is a fungal skin infection that forms a red, scaly, ring-shaped patch with a clearer center. Despite the name, there is no worm involved. It is contagious and can spread by contact with infected people, pets, or shared items.
Signs & Symptoms
-
A red, scaly, ring-shaped patch with a clearer center
-
An advancing, slightly raised, scaly border
-
Itching in and around the patch
-
One or several patches that slowly enlarge
-
May spread to other body areas if scratched
Why Does It Happen?
It's caused by common fungi (dermatophytes) that live on skin, animals, and surfaces. Warmth, moisture, and skin-to-skin or shared-item contact help it spread. Pets (especially kittens), gym mats, and shared towels are frequent sources. It is NOT caused by poor hygiene, though damp skin makes it easier to catch.
Treatment Options
Most cases clear with antifungal creams. Larger, widespread, or stubborn cases may need antifungal pills. Keep treating for the full recommended time even after it looks better.
ANTIFUNGAL CREAMS
Terbinafine, clotrimazole, or similar applied 1–2 weeks past clearing.
ORAL ANTIFUNGALS
Pills for widespread, stubborn, or hair-bearing area involvement.
TREAT THE SOURCE
Check and treat pets or contacts that may be the source.
KEEP SKIN DRY
Reducing moisture helps clearance and prevents return.
Tips for Managing It at Home
-
FOMITES: wash towels, bedding & clothing in hot water (≥50°C); don't share them
-
Disinfect shared surfaces (gym mats, gear) and have pets checked/treated
-
Don't scratch, then touch other body areas — it spreads the fungus
-
Keep the area clean and dry; finish the full course of treatment
When to Call Your Provider
-
No improvement after 2 weeks of antifungal treatment
-
The rash spreads widely or keeps coming back
-
Patches appear in the scalp or beard (may need pills)
-
Signs of bacterial infection: pus, swelling, or increasing pain
