The most typical bacterial infections of the skin are Impetigo and Folliculitis. Impetigo is a superficial infection of the skin caused by Staph or Strep bacteria and showing up as red, crusted, oozing patches on the skin. Folliculitis is a bacterial infection of the hair follicles created by Staph bacteria that shows up as red, tender pustules. Both Impetigo and Folliculitis respond well to oral and topical antibiotics.
Fungal infections of the skin typically appear as red, scaly patches in a ring shape. Because of the ring shape, these infections are commonly referred to as ringworm. The most frequently affected areas for fungal infections are the feet, the groin, and the arms and legs. These can be treated with both topical and oral medications.
Another common fungal infection of the skin is Tinea versicolor. This condition causes pink, white, or brown flat, scaly patches typically found on the trunk. These can be treated topically with antifungal medicines.
Two of the most common viral infections of the epidermis are warts and molluscum. Warts may occur anyplace and are dry with a cauliflower-like surface. Molluscum contagiosum occurs more frequently in children and they look like firm pimples. Both warts and Molluscum can be treated with liquid nitrogen or topical medicines.
