Ringworm of the body

Overview

Ringworm of the body (also called tinea corporis) is a common fungal infection of the skin. Despite its name, it is not caused by a worm. It causes a red, circular, ring-shaped rash that can be itchy.

Yes, ringworm of the body is very common worldwide. It affects people of all ages, especially in warm, humid climates.

Anyone can get ringworm, but it is more common in children, athletes, people who sweat a lot, and those in close contact with infected people or animals.

Symptoms

Common symptoms

• Ring-shaped, red, raised patches on the skin with a clear center
• Itching or burning on the affected area
• Scaling or cracking of the skin
• Patches may grow slowly and spread to other areas

Symptoms in children

• Same ring-shaped rash, often on the scalp or face
• May be more common in school-aged children
• Sometimes mistaken for other skin conditions like eczema

Symptoms in older adults

• Rash may be less typical, with more widespread patches
• Skin may be drier and more prone to cracking
• Healing might take a bit longer due to age-related skin changes

Causes

Main causes

• Infection with a type of fungus called dermatophyte (most often from soil, animals, or other people)
• Touching an infected person or animal (like cats, dogs, or farm animals)
• Sharing towels, clothing, bedsheets, or sports equipment with someone who has ringworm

Risk factors

• Living in warm, humid climates or spending a lot of time sweating
• Playing contact sports (wrestling, rugby) or using public showers
• Having a weakened immune system due to illness or medication
• Petting or handling animals that may carry the fungus

When to see a doctor

See a doctor urgently if:

• If the rash is very painful, oozing pus, or you have a fever
• If you have a weakened immune system and notice a rash

Book a routine appointment if:

• If the rash does not improve after a week of using over-the-counter antifungal cream
• If you are unsure whether the rash is ringworm
• If the rash is on the scalp or beard (needs special treatment)

Diagnosis

A doctor can usually diagnose ringworm just by looking at your skin and asking about your symptoms. Sometimes they may take a small scraping of skin to check under a microscope.

Tests that may be done

• Skin scraping: a gentle scrape of the rash to look for fungus under a microscope
• Wood's lamp: a special light that can make some types of fungus glow (not always used)
• Sometimes a culture to identify the specific fungus (rarely needed)

What to expect at your appointment

The doctor will examine your skin and may gently scrape a tiny piece of skin from the edge of the rash. This does not hurt. Results from a microscope can be ready in minutes; a culture takes a few weeks. Usually treatment starts right away.

Treatment

Ringworm is treated with antifungal medicines that kill the fungus. For mild to moderate cases, you can use creams, lotions, or sprays from the pharmacy. For severe or widespread cases, your doctor may prescribe oral (tablet) treatment. It is important to treat for the full recommended time, even if the rash improves.

Self-care at home

• Keep the affected area clean and dry
• Wash your hands after touching the rash
• Avoid sharing towels, clothes, or bedding until the rash is gone
• Use a separate towel for the rash area
• Wear loose, breathable clothing

Medical treatments

Your doctor or pharmacist can recommend an antifungal cream, spray, or lotion. You apply it to the rash and a little beyond the edge, usually once or twice a day for 2–4 weeks. If the infection is severe, on the scalp or nails, or does not respond to creams, your doctor may prescribe antifungal tablets. Always follow the instructions provided with your medicine.

When is surgery considered?

Surgery is not needed for ringworm of the body.

Living with this condition

Ringworm is easy to manage. Continue your treatment as directed and keep the area clean. The rash may itch, but try not to scratch. Wash your hands often. It usually clears up within a few weeks.

Lifestyle tips

• Shower after sweating, especially after sports
• Wear clean, dry clothes each day
• Don't share personal items like towels, razors, or sports gear

Diet and exercise

There is no special diet for ringworm. A healthy diet supports your immune system. You can continue to exercise, but shower and dry off well after sweating. Avoid tight clothing that traps moisture.

Mental health and emotional wellbeing

Having a visible rash can be embarrassing or stressful for some people. Remember that ringworm is very common and treatable. Most people recover fully without lasting marks. If you feel upset, talk to a trusted friend or your doctor.

Prevention

Yes, you can lower your risk by practicing good hygiene: wash your hands often, keep skin dry, avoid sharing personal items, and wear flip-flops in public showers. If your pet has signs of ringworm, take them to the vet.

Complications

If left untreated

• The rash may spread to other parts of your body
• Secondary bacterial infection if scratching causes breaks in the skin
• In people with weakened immune systems, the infection can become more widespread and harder to treat

Long-term outlook

With proper treatment, ringworm of the body usually clears up completely within a few weeks. It does not cause permanent damage to the skin in most cases. Even without treatment, it may improve on its own, but treatment speeds recovery and reduces the risk of spreading it to others.
