Ringworm is a contagious or contagious skin disease. In the language of medical science, it is called tinea. The disease is called Trichophytina or Trichophytosis because it is caused by the fungus Trichophyton. The fungal attack destroys the keratin protein of the skin and causes ringworm. Hence they are known as keratinophilic fungi. Ringworm infection is called dermatophytosis. The fungi that cause ringworm are called dermatophytes. Ringworm is named for this characteristic ringworm symptom.
