A simple scratch on your skin has the potential of growing into a large infection that needs more medical attention than a simple cleaning. You need to practice a method of infection control so that when you have some sort of injury no matter how small you give it the proper attention it needs. You need to be sure to properly cleanse the wound and apply the needed dressing so that you keep it clean and prevent any infection from happening. This will help allow the injury to heal quicker and keep you healthier. If you get an infection then your injury will hurt more and could become extremely lethal to you. Infection means you have bacteria and germs in the wound and can make a small injury become much worse in a short period of time. So when you get a cut make sure to take proper care of it so that you do not have any further issues with it.
