|Leaving a wound uncovered helps it stay dry and helps it heal. If the wound isn't in an area that will get dirty or be rubbed by clothing, you don't have to cover it.
If it's in an area that will get dirty (such as your hand) or be irritated by clothing (such as your knee), cover it with an adhesive strip (one brand: Band-Aid) or with sterile gauze and adhesive tape. Change the bandage each day to keep the wound clean and dry.
Certain wounds, such as scrapes that cover a large area of the body, should be kept moist and clean to help reduce scarring and speed healing. Bandages used for this purpose are called occlusive or semiocclusive bandages. You can buy them in drug stores without a prescription. Your family doctor will tell you if he or she thinks this type of bandage is best for you.
