Causes
Ringworm
Ringworm is caused by dermatophyte fungi, which include species such as Trichophyton and Microsporum. These fungi naturally reside on the skin, hair, and nails but can grow uncontrollably in warm, damp environments. Infection occurs through direct contact with an infected person, animal, or contaminated objects. The fungus can also spread from contaminated soil, although this is less common.
How Contagious is Ringworm?
Ringworm is highly contagious and can live on skin, surfaces, and in soil. It spreads through:
• Skin-to-skin contact: Direct contact with an infected person.
• Animal contact: Touching an animal with ringworm (e.g., dogs, cats, livestock).
• Contaminated objects: Using items such as towels, bedding, or gym equipment that have been in contact with the fungus.
• Soil contact: Rarely, through contact with infected soil.
Risk Factors
Who is at Risk for Ringworm?
Certain factors increase the risk of developing ringworm, including:
• Living in warm, humid climates.
• Close contact with infected individuals or animals.
• Sharing clothing, bedding, or towels with someone who has a fungal infection.
• Participating in sports with skin-to-skin contact, such as wrestling.
• Wearing tight or restrictive clothing.
• Having a weakened immune system.
• Frequent use of public locker rooms or showers.
