Fungi: what they are and how to handle common infections

Fungi are tiny organisms that live on skin, nails, and sometimes inside the body. Most are harmless, but a few cause infections like athlete's foot, ringworm, jock itch, vaginal yeast infections, and nail fungus. The good news: many of these are easy to treat if you spot them early and use the right approach.

Common fungal infections and quick fixes

Athlete's foot shows as red, itchy, flaky skin between toes. Use an over-the-counter antifungal cream with clotrimazole or terbinafine for 1–2 weeks after symptoms clear. Keep feet dry, wear breathable shoes, and swap socks daily.

Ringworm is a round, scaly patch on skin. Topical antifungals usually do the job. Apply twice daily and don’t stop just because it looks better—finish the full course to prevent return.

Vaginal yeast infections cause itching, burning, and thick discharge. Short courses of topical azole creams or a single-dose oral fluconazole (prescription) often work. If you’re pregnant, check with a clinician before taking oral meds.

Nail fungus (onychomycosis) is tougher. Topical treatments can help early cases, but many people need prescription oral antifungals like terbinafine or itraconazole for several months. Nail labs and photos can track progress.

Practical tips to prevent fungal problems

Keep skin dry and clean. Fungi love warm, moist places—so dry off after showers, change out of sweaty clothes quickly, and rotate shoes. Use cotton socks or moisture-wicking fibers. Avoid walking barefoot in public showers and locker rooms.

Don’t share towels, nail clippers, or shoes. If you treat an infection, wash towels and bedding in hot water to stop reinfection. For athletes, anti-fungal powders in shoes can reduce risk.

Be cautious with topical steroids. They can make a fungal infection look better at first and then worse. If a rash doesn’t respond to steroid cream, ask a clinician to check for fungus.

Some people—those with diabetes, weakened immune systems, or poor circulation—get more severe fungal infections. They should act fast and see a clinician early.

When a simple cream doesn’t clear things up, tests help. A quick skin scraping, nail clipping, or swab can confirm fungus and guide stronger prescription choices.
