Fungal skin is an infection of the skin caused by dermatophytes fungi and can occur in any part of the body. Fungal skin infections of the foot, widely referred to as “athlete’s foot” or “foot rot“, are medically termed tinea pedis and are a very common skin condition of the foot. Patients with tinea pedis will often complain of itch, dry flaky skin or even tiny blisters on the affected areas.
Causes of Fungal Skin
Fungal skin infections are opportunistic infections, which means that will infect when given the right conditions and environment. Infection typically starts from direct contact and other risk factors play a part in allowing the infection to manifest.
Risk factors of fungal skin include:
- Hot and humid environment (e.g sweaty feet, enclosed footwear)
- Poor foot hygiene
- Immunocompromised individuals (e.g diabetes, steroidal therapy, transplant patients)
- Poor blood circulation to the foot (e.g peripheral arterial disease)
- Existing fungal infections in other parts of the body (e.g fungal nails)
