Fungal Rashes: What They Look Like, Causes & When to Get Care

A new itchy or unusual rash can be frustrating—especially when you’re not sure what’s causing it.

Some rashes are caused by allergies, irritation, heat, insects, or other skin conditions. Others are caused by fungi.

Fungal skin infections are common and can affect children and adults. One of the best-known examples is ringworm, which can cause an itchy, scaly, ring-shaped rash. Despite its name, ringworm isn’t caused by a worm—it’s a fungal infection. (CDC)

At Virtual Urgent Care (VUC), we help patients understand common skin concerns and provide convenient care when appropriate, along with preventative information to help you stay healthy.

🍄 What Is a Fungal Rash?

A fungal rash occurs when certain fungi grow on the skin.

Common fungal infections include:

Ringworm – often causes an itchy, scaly, ring-shaped rash
Athlete’s foot – commonly affects the skin between the toes and feet
Jock itch – affects the groin and inner thighs
Scalp ringworm – can cause scaly areas and hair loss
Fungal nail infections – can cause nails to become thick, discolored, or brittle (CDC)

Fungal infections can occur on different parts of the body and may look different depending on where they develop.

👀 What Does a Fungal Rash Look Like?

One common sign of ringworm on the skin is a round or ring-shaped patch with a raised, scaly border. The center may appear clearer than the outer edge, and the rash can become larger over time. (American Academy of Dermatology)

Other possible symptoms include:

Itching
Scaling or peeling
Dry or cracked skin
Red, brown, gray, or darker areas depending on skin tone
Burning or irritation
A rash that gradually spreads

Importantly, not every fungal infection has a classic ring-shaped appearance. Athlete’s foot, scalp infections, groin infections, and nail infections can look quite different. (CDC)

🌡️ Why Do Fungal Rashes Happen?

Fungi tend to thrive in warm, moist environments.

Your risk can increase with:

Excessive sweating
Hot and humid weather
Damp clothing
Tight shoes
Shared locker rooms
Walking barefoot in communal areas
Contact with an infected person
Contact with an infected pet
Sharing towels, clothing, or other personal items (CDC)

This is one reason fungal skin infections can become particularly troublesome during warm-weather months.

🏊 Summer Activities Can Increase Your Risk

Swimming, sports, summer camps, gyms, and outdoor activities can create more opportunities for fungal infections to spread.

Help protect your skin by:

Keeping your skin clean and dry
Changing out of sweaty clothing
Changing socks regularly
Wearing sandals in public showers and locker rooms
Avoiding shared towels and personal items
Showering after sports or exercise
Keeping athletic equipment clean (CDC)

🚫 Don’t Assume Every Rash Is Fungal

A rash can have many different causes.

Eczema, allergic reactions, contact dermatitis, insect bites, bacterial infections, and other skin conditions can sometimes look similar to a fungal rash.

That’s why it’s important to avoid automatically treating every itchy rash as a fungal infection.

The CDC notes that symptoms of ringworm can resemble other skin and nail conditions, and testing may sometimes be needed to confirm the diagnosis. (CDC)

⚠️ One Important Tip

Avoid using steroid creams on a rash that could be ringworm unless a healthcare professional specifically recommends them. The CDC warns that steroid creams can make ringworm worse. (CDC)

🩺 When Should You Get Care for a Fungal Rash?

Consider getting medical advice if:

The rash is spreading
The rash is painful
The itching is severe
The skin is cracking or bleeding
There is drainage or pus
The rash involves the scalp
Hair loss develops around the affected area
The rash involves the nails
The rash isn’t improving with appropriate treatment
You’re unsure what is causing the rash

Scalp fungal infections deserve particular attention because they can cause hair loss and often require prescription treatment. (CDC)

💊 How Are Fungal Rashes Treated?

Treatment depends on the location and severity of the infection.

Some fungal infections on the skin can be treated with over-the-counter antifungal medications, while other infections—particularly those involving the scalp or nails—may require prescription medication. (American Academy of Dermatology)

If an antifungal medication is recommended, use it exactly as directed and for the recommended length of time. Stopping treatment too early can allow the infection to return. (American Academy of Dermatology)

💻 How VUC Can Help

A new rash can be difficult to identify on your own.

Virtual Urgent Care (VUC) can provide convenient evaluation for many common, non-emergency skin concerns.

During a virtual visit, a VUC provider can:

Review your symptoms
Ask about when the rash started
Discuss possible causes
Review photos of the affected area when appropriate
Recommend appropriate treatment
Determine whether an in-person evaluation may be needed
Provide prevention information to help reduce future skin problems

At VUC, our goal isn’t simply to help you get better. We also provide preventative health information so you can better understand your health and stay healthy.

🧼 How to Prevent Fungal Rashes From Coming Back

Once you’ve had a fungal infection, prevention can help reduce the chance of getting another one.

Try to:

Keep affected areas clean and dry
Change socks and underwear daily
Avoid sharing towels or clothing
Wear breathable clothing
Wear shower shoes in communal showers
Wash your hands after touching an affected area
Keep sports equipment clean
Avoid close contact with someone who has an active fungal infection
Have pets evaluated if they develop suspicious skin problems (CDC)

📝 Preparing for a VUC Visit

Before your virtual appointment, be prepared to tell your provider:

When the rash began
Where it first appeared
Whether it has spread
Whether it itches, burns, or hurts
Any recent swimming, sports, gym, or outdoor activities
Whether you’ve tried any creams or medications
Whether anyone else in your household has a similar rash

Showing affected area in good lighting may also help your provider understand what you’re experiencing.
