Overview
Ringworm, despite its name, is not caused by a worm but by a group of fungi known as dermatophytes. These fungi infect the skin, hair, and sometimes nails of animals, including pets like dogs, cats, and other small animals. It's a highly contagious condition that can spread to humans.
Causes
Ringworm is caused by several types of fungi, with the most common being Microsporum canis, Microsporum gypseum, and Trichophyton mentagrophytes. These fungi thrive in warm, moist environments and can easily spread through direct contact with an infected animal or contaminated objects.

Emergency Signs
While ringworm is generally mild, severe skin infections or widespread lesions may require urgent attention.
Diagnosis
Diagnosis is typically made through a physical examination and confirmed with diagnostic tests such as fungal cultures, Wood's lamp examination, or skin biopsies.
