What Is a fungal skin infection? Symptoms, causes, and treatments

Fungal skin infections can cause discomfort, itching, and soreness on areas like the skin, scalp, and nails. These infections are common, and with the help of a GP (General Practitioner) or Advanced Clinical Practitioner (ACP), they can be diagnosed and treated effectively.

What is a fungal skin infection?

A fungal skin infection occurs when a fungus grows on or inside the skin, causing irritation. While most infections aren’t dangerous, they can be uncomfortable and may spread if untreated.

The most common fungal skin infections include:

What are the causes of fungal skin infections?

Fungal skin infections are caused by fungi, such as candida yeast or dermatophytes, that thrive in warm, moist environments.
Common causes include:

  • Skin-to-skin contact with an infected person or animal.
  • Damp conditions, like sweaty shoes or wet skin.
  • Sharing items such as towels, hairbrushes, or bedding.
  • Weakened immunity, diabetes, or obesity.

How are fungal skin infections treated?

For most fungal skin infections, treatment begins with a visit to your local pharmacy. A pharmacist can recommend antifungal creams, sprays, or gels to clear the infection.

If symptoms persist or worsen, a clinician may prescribe:

  • Antifungal tablets for severe or stubborn infections.
  • Topical treatments for ringworm on the scalp.
  • Antibiotics if a secondary bacterial infection develops.
