Ringworm is caused by a fungal infection, not by worms. The fungi responsible are a group called dermatophytes, with the most common genera being Trichophyton, Microsporum, and Epidermophyton
. These fungi thrive in warm, moist environments and live on the dead tissues of the skin, hair, and nails
. The infection is highly contagious and can spread through:
- Direct skin-to-skin contact with an infected person
- Contact with infected animals, such as cats, dogs, or farm animals
- Touching contaminated objects like clothing, towels, combs, brushes, or sports equipment
- Contact with infected soil, although this is less common
Risk factors that increase the likelihood of getting ringworm include living in warm or humid climates, participating in contact sports (e.g., wrestling), sharing personal items, wearing tight or restrictive clothing, having a weakened immune system, and certain health conditions like diabetes or obesity
. In summary, ringworm is caused by specific fungi that infect the skin and spread easily through contact with infected people, animals, objects, or environments conducive to fungal growth
