Fungal Infections

What are Fungal Infections?

Fungal infections, also known as “ring worm,” are skin diseases caused by a fungus. They can affect anyone and can appear on different areas of the body. Common fungal infections include athlete’s foot, ringworm, and yeast infections, which often occur in warm, moist environments. Most fungal infections affect the skin, hair, or nails, but some can be more serious and even life-threatening if left untreated.

Many fungal infections are caused by the overgrowth of natural fungi on the body or by compromised immunity. Fungal infections occur through direct contact with contaminated surfaces, inhalation of fungal spores, or entry via skin injuries.

Risk factors for fungal infections depend on the type of fungus involved and individual health conditions. Different types of fungi cause different types of fungal infections, and they can be contagious, spreading from one person to another. Some common types of fungal infections include:

Ringworm

Ringworm is not a worm at all, but a fungal skin infection. The medical name for ringworm on the body is tinea corporis. It is named for the circular shape of the rash with winding edges. Symptoms include a red, circular, flat sore that can appear alongside scaly skin, often forming a distinctive ring-shaped rash with raised edges. Patches or red rings may overlap. Ringworm is mildly contagious and can spread through direct contact or contaminated objects. Treatment is often based on symptoms and may include antifungal medications that are put on the skin or taken by mouth. Ringworm can be confused with other skin conditions, so accurate diagnosis is important.

Athlete’s Foot

This fungal infection can be found on the foot. The medical name is tinea pedis, also known as athlete’s foot. This fungus grows best in warm, moist environments such as socks, shoes, swimming pools, public showers, and locker rooms. People who wear shoes that are tight or non-breathable, do not change their sweaty socks often enough, or who use public pools are most likely to get athlete’s foot. Symptoms often include peeling, cracking, scaly feet, itching, burning, and blisters. It is usually treated with an antifungal medicine that is put on the skin.

Jock Itch

This is caused by a type of fungus called tinea, which loves warm, moist areas like the inner thighs, buttocks, and genitals. Infections are most likely to occur in the summer or warm, wet climates. Symptoms include itching or burning on your groin or thigh, a red, circular rash, or peeling, cracking skin. Treatment includes over-the-counter fungal medications or prescription creams. It is important to keep the affected area clean and dry and to change your underwear daily.

Yeast Infection

Yeast infections of the skin are caused by a type of yeast called candida. These are known as candida infections and can affect various parts of the body. Candida albicans is the most common species causing these infections. They are common in moist, warm, creased areas of the body such as the armpits and groin.

A vaginal yeast infection is a frequent type of candida infection, presenting with symptoms like itching, burning, and abnormal discharge, and is diagnosed using microscopic examination. In infants, diaper rash can be caused by candida overgrowth, which should be distinguished from other types of rashes for proper treatment.

Taking antibiotics can increase the risk of developing yeast infections by disrupting the normal balance of bacteria and fungi. Symptoms include a rash, patches that ooze clear liquid, itching, burning, and pimple-like bumps. Treatment may include medicated creams or anti-yeast medications taken by mouth.

Fungal Infection of the Nail

Fungal infections that affect toenails, fingernails, or nail beds is also known as onychomycosis. It usually starts as a small, lightly-colored spot on the nail that spreads deeper over time. This can cause the nail to become thicker and more brittle. Common signs include white or yellow streaks under the nail, scaling under the nail, thick or brittle nails, or lifting off of the nail bed. Treatment may include a prescription nail lacquer or antibiotics taken by mouth.

To prevent the spread of fungal nail infections, do not share nail clippers with others.

Fungal Infection Complications

Fungal infections can sometimes lead to more serious health problems, especially if they are not treated promptly or if the person affected has a weakened immune system. People with weakened immune systems, such as those undergoing chemotherapy, living with chronic illnesses, or taking certain medications, are at a much higher risk for these complications.

Even common fungal skin infections and fungal nail infections can cause problems if left untreated. For example, a fungal nail infection can spread to the surrounding skin, leading to additional skin infections and discomfort. Subcutaneous fungal infections, which start beneath the skin, can sometimes reach other parts of the body, including the lungs, heart, or even the brain, resulting in serious infections that require urgent medical care.

To prevent fungal infections and reduce the risk of complications, it’s important to keep your skin clean and dry, especially in areas prone to moisture like the inner thighs. Avoid sharing personal items such as nail clippers, and wear sandals or shoes in public places like locker rooms to minimize exposure to fungal spores. Good hygiene practices, such as washing hands regularly and avoiding direct contact with infected skin or mucous membranes, can also help prevent the spread of infection.

If you notice symptoms of a fungal infection, such as a persistent rash, thick nails, or scaly skin, it’s important to seek medical attention. Fungal infection diagnosis may involve a physical exam, laboratory tests, or imaging studies. Treatment options depend on the type and severity of the infection and may include antifungal medications in the form of creams, ointments, or oral prescriptions. In cases of severe infections, hospitalization and more intensive treatment may be necessary.

By taking steps to prevent fungal infections and seeking prompt treatment when symptoms occur, you can help protect yourself from the complications associated with these common but potentially serious infectious diseases.
