Understanding Fungal Infections

When it comes to fungal infections, they’re all over the map. From your scalp to your toes—and many places in between—fungal infections can affect almost any part of the body. They are often itchy, sometimes painful, and can range from a minor annoyance to a persistent condition that requires medical treatment.

Depending on the type of infection, your skin may flake, blister, crack, or become discolored. Scratching can break the skin, increasing the risk of a secondary bacterial infection.

The first step toward successful treatment is an accurate diagnosis. Your Midwest Dermatology provider will review your medical history, examine your skin, and, when appropriate, perform testing such as a skin scraping or culture to confirm the diagnosis.

Treatment depends on the type and location of the infection and may include prescription creams, lotions, solutions, or oral antifungal medications.

Types of Fungal Infections

Athlete’s Foot (Tinea Pedis)

Athlete’s foot is a fungal infection that most often develops between the toes or on the soles of the feet. Symptoms may include itching, burning, scaling, peeling, cracking, or blistering of the skin.

The infection is commonly acquired by walking barefoot in warm, moist environments such as locker rooms, public showers, and around swimming pools.

Ringworm (Tinea Corporis)

Despite its name, ringworm is not caused by a worm. It is a fungal infection that typically appears as a circular, red, scaly rash with a raised border.

Ringworm is contagious and may spread through:

  • Direct skin-to-skin contact
  • Shared towels, clothing, brushes, or combs
  • Locker rooms, public showers, and other contaminated surfaces
  • Pets, particularly cats, that carry the fungus

Although ringworm is more common in children, it can affect people of all ages.

Nail Fungus (Onychomycosis)

Nail fungus affects the fingernails or toenails, causing them to become thickened, yellow, cloudy, brittle, or crumbly. As the infection progresses, the nail may begin separating from the nail bed.

Nail fungus rarely resolves without treatment and may gradually worsen over time.

Tinea Versicolor

Tinea versicolor is caused by an overgrowth of yeast that normally lives on the skin. It produces lighter or darker patches that are most often found on the chest, back, shoulders, neck, and upper arms.

Some people also notice fine scaling or mild itching. While harmless, the color changes can become more noticeable during the summer months when surrounding skin tans.

Ringworm of the Scalp (Tinea Capitis)

Tinea capitis is a fungal infection of the scalp that occurs most often in children. It may cause scaling, itching, patches of hair loss, or broken hairs.

Because it is contagious, prompt diagnosis and treatment are important to help prevent it from spreading to others.

Jock Itch (Tinea Cruris)

Jock itch is a fungal infection that affects the groin and upper thighs. It typically causes a red, itchy rash that may spread outward and can occasionally blister or ooze.

Warm, moist environments and friction can contribute to its development.

Candidiasis

Candidiasis is a yeast infection that develops in warm, moist areas of the body or on mucous membranes. It commonly causes redness, irritation, itching, and discomfort.

How Are Fungal Infections Diagnosed?

Many skin conditions—including eczema, psoriasis, and dermatitis—can resemble a fungal infection. Because treatment depends on the correct diagnosis, your Midwest Dermatology provider will carefully examine your skin and, when appropriate, may perform a skin scraping or culture to confirm the diagnosis.

Treatment Options

Treatment depends on the type and location of the fungal infection. Your dermatologist may recommend:

  • Prescription antifungal creams, lotions, or solutions
  • Oral antifungal medications for more extensive infections
  • Medicated shampoos for scalp infections
  • Skin care recommendations to help prevent future infections

Your treatment plan will be tailored to the specific type of fungal infection and your individual needs.

When Should You See a Dermatologist?

Schedule an evaluation if you have:

  • A rash that isn’t improving with over-the-counter treatment
  • Thickened, discolored, or crumbling nails
  • A spreading or persistent rash
  • Frequent or recurring fungal infections
  • A rash that becomes painful, swollen, or shows signs of infection

Early diagnosis can help relieve symptoms, prevent the infection from spreading, and get you on the right treatment sooner.
