Sometimes, a cut, scratch, or abrasion starts out as no big deal, but then gets infected. An infection (say: in-FEK-shun) happens when there are too many germs for your body’s white blood cells and immune system to handle.
Infected wounds may hurt, look red and swollen, feel warm to touch, or contain pus, which is a yellowish or greenish thick liquid. Infected wounds also can cause a fever. If your cut, scratch, or abrasion looks infected, tell your parent. You may need to see a doctor for antibiotics to get rid of the infection.
Luckily, most cuts, scratches, and abrasions will go away on their own, thanks to your body’s amazing ability to heal itself.
