Psoriasis is characterized by thickened, red areas of skin covered by white/silvery scales. Psoriasis is not contagious and cannot be spread to another person by any means. The development of psoriasis is thought to be inherited because it tends to occur in families. Aggravating factors may include injury to the skin, change of season, general health factors, infections, and certain medications. The eruption can range from mild to severe and can be treated with topical medications, light therapy, and, in severe cases, internal and injectable medications.
