What is the typical treatment for tinea corporis?

Tinea corporis, commonly known as ringworm, is a fungal infection that affects the skin on various parts of the body. The typical treatment for this condition involves the use of topical antifungals, such as miconazole. Topical antifungals are effective because they directly target the fungi causing the infection, eliminating the pathogen from the affected area. Miconazole and similar medications are designed to be applied directly to the skin, where they can penetrate the fungus and disrupt its growth and reproduction.

Other treatments offered in the choices are not suitable for tinea corporis. For example, systemic griseofulvin is generally reserved for more severe cases or when the infection does not respond to topical treatments, such as when it affects the scalp or nails. Vaccination for tetanus is unrelated to fungal infections and has no role in treating tinea corporis. Surgical removal of the affected nail is specifically applicable to fungal nail infections (onychomycosis) and not appropriate for a skin condition like tinea corporis. This makes the choice of topical antifungals like miconazole the best and most standard treatment method for tinea corporis.
