Ringworm is a fungal infection that is highly contagious and can easily spread to other parts of the body through contact with contaminated surfaces, including clothing, towels, and other personal items, as well as direct skin-to-skin contact with an infected person or animal. The infection is caused by dermatophytes, which thrive in warm, moist environments and can live on surfaces for extended periods, making it imperative for barbers and other professionals in the personal care industry to maintain strict hygiene practices to prevent transmission.

In contrast, psoriasis is a chronic autoimmune condition that is not contagious, as it is related to immune system dysfunction rather than an infectious agent. Ivy dermatitis, often a reaction to poison ivy, is caused by contact with an allergenic oil in the plant, and while it can cause a rash, it does not spread from one person to another or through surfaces. Eczema, similarly, is a chronic skin condition driven by individual genetic and environmental factors and is not infectious in nature. This differentiates ringworm as the clear answer regarding the transmission of a condition through contaminated surfaces.
