Skin fungus

A red, itchy, scaly rash can be ugly and drive you crazy. However, most yeast infections are not dangerous and you can usually treat them easily with creams. If you are prone to recurring yeast infections, talk to your healthcare provider about how to prevent the rash from returning.

What is skin fungus?

A fungus is a small organism, such as mold or fungus. Fungi are everywhere - in the air and in the water and on the human body. About half of all fungi are harmful. When harmful fungi land on your skin, it can cause a yeast infection. 

Who is at risk of getting a yeast infection?

Anyone can develop a fungal rash. Superficial infections of the skin and nails are cited as the most common form of infection, affecting up to 20–25% of the world's population at any given time. For example, athlete's foot frequently affects otherwise healthy people. You may be more at risk of developing skin rashes if you:

Have a weakened immune system (for example, if you are taking immunosuppressant drugs, have a disease that weakens the immune system or are undergoing chemotherapy).

  • Take long-term or high doses of antibiotics.
  • is overweight.
  • have diabetes
  • Try a new skin care product.
  • Experience incontinence (eg, diaper rash in babies).
  • profuse sweating
  • pregnant

What does a yeast infection look like?

A fungal skin infection often looks bright red and can spread over a large area. A fungal skin rash may also have characteristics that include:

  • The color is more intense at the border.
  • The scale is more intense at the border
  • Small, more defined lesions (pustules) at the edges of the rash area.
Where does a yeast rash appear?

Rashes can appear anywhere on the body. It is more common in areas with skin folds such as groin, buttocks or thighs.

What are the different types of skin eruptions?

Tinea is the medical name for fungal skin infections. Types of yeast infection include:

Athlete's Foot (Tinea Pedis): The most common type of fungal infection, this condition is often spread when people walk barefoot in public bathrooms or locker rooms. The skin between your toes turns white and starts peeling. Athlete's foot can also affect the sole (bottom) of the foot.

Nail Fungus (Onychomycosis): This infection is a common foot problem. It usually affects toenails, which become yellow and thick, and break easily.

Jock Itch (Tinea Cruris): A rash on the groin area, jock itch affects men more than women.

Scalp Ringworm (Tinea Capitis): This rash mostly occurs in children. It causes hair loss, but with proper treatment the hair usually returns.

Ringworm (Tinea corporis): This "catch-all" term is what health care providers call a rash that doesn't fit into any other category. Rashes often form a ring shape.

Symptoms and causes

What causes a fungal rash?

When your skin comes in contact with the harmful fungus, the infection can cause a rash. For example, if you borrow a pair of shoes from someone who has athlete's foot, the fungus can come in contact with your feet and infect you. The rash is often spread from person to person or animal to person by direct contact.

What are the symptoms of a yeast infection?

A yeast rash is often red and itchy or burning. You may have a red, swollen bump or scaly, flaky patch that looks like a pimple.

Diagnosis and testing

How is a yeast infection diagnosed?

A health care provider may be able to diagnose a yeast infection by looking at the rash and asking about your symptoms. Often, the diagnosis can be confirmed by examining scale scrapings under a microscope (KOH preparation). In some cases, you may need a fungal culture test to help identify a specific fungus and determine the best treatment for you.

During a yeast culture test, your provider may take a small sample of skin (biopsy) or fluid (aspiration). For severe infections, you may need blood tests.

Management and treatment

How to treat skin fungus?

Treatments for skin fungus include:

Antifungal creams, many of which are available over the counter.
Stronger prescription medications, which can work faster.
Oral medication, if the yeast infection is severe.

Can I treat a fungal rash at home?

It is important for your health care provider to watch the rash, especially if it is the first time the rash has appeared. Your provider can diagnose it and discuss the best steps to treat it. Treating a fungal rash with steroid-containing anti-itch creams can make the infection worse and more difficult to treat.


How can I prevent a yeast infection?

In some people, fungal rashes return (recur) even after treatment. Recurrent infections can be due to genetics - you may be more prone to developing these infections. These measures can help prevent a rash from recurring or developing in the first place:

Good foot hygiene

Change your socks and wash your feet often. Avoid shoes made of plastic, which is not breathable.

Don't walk barefoot, especially in places that may get wet, like gym showers and locker rooms.

When trimming toenails, cut straight across the nail. If you have a toenail, you may need to see a podiatrist to get it taken care of. And if you have a nail fungus infection, don't use the same nail clipper on healthy nails and infected nails.

Using the right medicine

If your healthcare provider prescribes a cream (or recommends you use an over-the-counter cream), use the medication as long as directed. Even after you no longer see the rash, the fungal infection may still be present, so keep applying the cream for as long as your provider advises.

Your health care provider may recommend the same type of treatment for all members of your family. Often, people who live together can pass an infection back and forth. Treatment for each will help ensure that the infection is truly gone.

Talk to your health care provider about whether you should use regular antifungal creams on your feet and nails to help prevent infections.

Using an antifungal powder in your shoes daily can help prevent athlete's foot.

Outlook / Forecast

How long will my skin rash last?

How long the treatment takes to work may vary from person to person. It usually takes a few days to a few weeks for it to clear. But the fungal infection can return. Talk to your health care provider about ways you can prevent the infection from coming back.

When should I see my doctor about a rash?

Most of the rash is not serious. But it's always a good idea to see your health care provider if you have skin changes. Your provider may recommend a course of treatment to make you feel better and to diagnose any underlying conditions.

Call your health care provider or go to the emergency room if a rash occurs:

  • All over your body.
  • Sudden onset and rapid spread.
  • Painful, blistered or infected.
  • Accompanied by fever.

A note from the Cleveland Clinic

Fungal skin rashes can be uncomfortable and itchy but are treatable. See your health care provider if you notice any rash or changes on your skin. Usually, a course of antifungal cream (either prescription or over-the-counter) will clear the rash and relieve the itching. Your health care provider can also discuss preventative measures to prevent the rash from returning.
