After a burn, it is possible to disinfect with povidone-iodine. Povidone-iodine has a broad spectrum of antibacterial effects and can kill proliferating bacteria, fungi, and some viruses. After a burn occurs on the skin, the first step is to reduce the temperature of the skin, which can be done by soaking in running tap water or cold water for more than half an hour to alleviate pain. Then, disinfect with povidone-iodine. After disinfecting with povidone-iodine, apply burn moistening cream locally, and then wrap it with sterile gauze. Change the dressing once a day, and after dressing, try not to come into contact with water to prevent infection. Also, avoid friction between the wound and the gauze, as this could affect the healing of the wound. Generally, mild burns can heal in about two weeks.
