Solution

Cause Ringworm is a common fungal infection caused by many fungi belonging to the genera Microsporum, Trichophyton and Epidermophyton. It is called ringworm because of the ring-shaped lesions it produces on the skin.

  1. It is highly contagious and spreads through direct contact with an infected person.
  2. It spreads through personal articles and clothes of the infected person, towels, combs, garments, etc.
  3. Ringworms may also be acquired from the soil.

The fungus attacks the epidermis (scalp, groin, skin and nails) and produces a patch of inflamed tissue which spreads outwards and heals in the centre, giving a ring-like appearance. Heat and moisture help the fungus grow and thrive in skin folds such as the groin and toes. Treatment is by applying a fungicide cream or powder to the affected area.
