What Causes Fungus on Skin?
Skin fungus, also known as a fungal skin infection or dermatophytosis, arises from contact with harmful fungi. These fungi thrive in moist, warm environments and frequently affect areas of the body that trap moisture or experience friction.
-
Moisture and Friction: Areas like the feet (athlete's foot), groin (jock itch), and skin folds are particularly susceptible due to their tendency to retain moisture and experience friction. [Source: Cleveland Clinic, WebMD, Healthline]
-
Weakened Immune System: Individuals with compromised immune systems, such as those with HIV/AIDS, cancer, or undergoing cancer treatment, are at a higher risk of developing severe fungal infections. [Source: Cleveland Clinic]
-
Underlying Medical Conditions: Poor circulation and diabetes can also increase susceptibility to fungal skin infections. [Source: Cleveland Clinic]
-
Overgrowth of Fungi: Some fungal skin infections, like tinea versicolor, result from an overgrowth of naturally occurring yeast on the skin, disrupting normal pigment production and causing discolored patches. [Source: Mayo Clinic, Cedars-Sinai]

Specific Fungi: Different fungi cause various types of skin infections. Candida albicans, for example, is a common cause of diaper rash in infants and other cutaneous candidiasis. [Source: Mount Sinai]

Contact with Contaminated Surfaces: Borrowing shoes or using contaminated towels can expose you to harmful fungi and lead to infections. [Source: Cleveland Clinic]
Common Types of Fungal Skin Infections:
- Athlete's foot (tinea pedis): Usually starts between the toes in sweaty feet. [Source: Mayo Clinic]
- Jock itch (tinea cruris): Affects the groin area. [Source: WebMD]
- Ringworm (tinea corporis): Creates circular, itchy rashes on the body. [Source: WebMD]
- Yeast infections: Often caused by Candida species. [Source: WebMD]
- Tinea versicolor: Causes discolored patches due to yeast overgrowth. [Source: Mayo Clinic]
Important Note:
Untreated fungal skin infections can worsen and spread. If you suspect a fungal infection, consult a healthcare professional for proper diagnosis and treatment. [Source: Bupa]
