An itchy, scaly rash between your toes. A red patch on your arm that keeps spreading. Thick, yellow toenails that seem impossible to clear. These problems can all be caused by fungal infections , but they are not necessarily the same infection—and they do not always require the same treatment. Fungal skin infections are extremely common and can affect the skin, feet, groin, scalp, nails and other areas of the body. Many mild infections can be treated successfully with antifungal medication, but others require prescription treatment or testing to make sure the rash is actually fungal. Quick Takeaway: Most common fungal skin infections are caused by dermatophytes or yeasts. Keeping skin dry, avoiding shared personal items and using the correct antifungal treatment can help.

Finding mold on a wall can be unsettling, but the most important thing to understand is this: Removing the visible mold is only half the job. You also need to find out why the wall became damp in the first place. Mold can grow on drywall, paint, wallpaper, wood, insulation and other building materials whenever enough moisture is present. That moisture may come from high indoor humidity, condensation, a leaking pipe, a roof or window leak, or previous water damage. Quick Answer: For a small area of wall mold, first stop the moisture source, protect yourself with gloves, eye protection and at least an N95 respirator, remove or clean contaminated material as appropriate, and dry the area completely. Larger or complicated mold problems may require professional remediation. Why Does Mold Grow on Walls? Mold spores are naturally present indoors and out...
