Question

How infections can be avoided

Answer 1

Start with washing hands. That is a big deal when it comes to any sickness or infection inside the body or outside.
(Is the infection on the inside of outside?)
Inside: eat healthy. Stay clean. Don’t put anything in your mouth that doesn’t belong. Wash your hands. Don’t touch your eyes, ears, nose, or mouth without clean hands.
Outside: keep the potential infected area clean. Don’t get dirt or anything in it and don’t let anything touch it. Keep it covered and clean. Leave it uncovered to dry out if wet. Clean with alcohol/peroxide. Keep covered with a clean bandage, changed every few hours.
