Do fungal infections come and go or do they have to be treated?

Fungal infections can go on their own; however, most of the time they need to be treated in order to prevent further complications. If left untreated, some fungal infections can cause serious health problems or spread to other parts of the body. In fact, some are life-threatening, like candida. It often helps to keep the affected area clean and dry. Antifungal treatments that the doctor can prescribe are sometimes required, depending on the severity of the infection.
