That red ring-shaped rash with raised edges — that’s probably ringworm, a contagious fungal infection. How did you get it? Is it dangerous? Can it be treated?

In this article, we’re going to discuss ringworm’s causes, how it’s diagnosed, and why you need treatment from a board-certified dermatologist.

What is Ringworm and What Causes It?

Ringworm is a fungal infection that is usually transmitted to humans by direct contact, or from an animal’s hair and dander. Ringworm infection can cause a red ring-shaped rash with raised edges, usually on the skin of the hands, feet, armpits, or groin. The ringworm rash may itch and worsen during warm weather periods.  Sufferers should try to avoid skin-to-skin contact with other people as well as animals to prevent the further spread of this fungal infection.

How Is Ringworm Diagnosed and Treated?

A topical anti-fungal cream is often prescribed for ringworm.

A ringworm diagnosis is usually made by examining the skin to identify the tell-tale signs — scaly, ring-shaped lesions. An exam can also be done with a special microscope to detect ringworm in skin scrapings or hair samples.

Ringworm is often treated with topical anti-fungal medications. Treatments prescribed may depend on the severity of the rash and the type of fungus present.

If left untreated, it can spread to other parts of the body. It can also be a contagious infection that is passed from person to person or through contact with animals. It’s important to seek care for ringworm and other skin conditions with a board-certified dermatologist to prevent complications and spread.
