What is true about all forms of tinea?

Tinea, commonly known as ringworm, is a fungal infection that affects the skin, hair, or nails. It is categorized as a contagious infection caused by dermatophytes, which are a group of fungi that thrive on keratin found in these body parts. The contagious nature of tinea is a key characteristic; it can be transmitted through direct contact with an infected person or by sharing personal items like clothing, towels, or combs.

This infectious quality emphasizes the importance of proper hygiene and sanitation in preventing its spread, making it crucial for barbers and stylists to be aware of. Although localized treatments exist to manage and clear these infections, the inherent contagiousness of tinea is what primarily distinguishes it in discussions about fungal conditions, reinforcing the need for timely and safe practices in both personal care and professional environments.

In contrast, the other options do not accurately characterize all forms of tinea. For example, not all tinea infections are severe, and while some might benefit from localized treatments, the infection is inherently contagious, which is the defining aspect of tinea.
