Why does a cut on your skin need to be protected against infection?

When you cut your skin, you create an opening that allows germs to enter your body. These germs can cause infections, which are characterized by redness, swelling, pain, and heat. In some cases, infections can be life-threatening.

There are a number of things you can do to protect a cut on your skin against infection, including:

* Wash the cut thoroughly with soap and water. This will help to remove any dirt or debris that may contain germs.

* Apply a bandage to the cut. A bandage will help to keep the cut clean and dry, and it will also help to protect it from further injury.

* Change the bandage regularly. This will help to prevent the bandage from becoming contaminated with germs.

* Keep the cut clean and dry. Avoid swimming or bathing in dirty water, and try to keep the cut out of direct sunlight.

* Take antibiotics if prescribed. If your doctor prescribes antibiotics, be sure to take them exactly as directed.

By following these steps, you can help to protect a cut on your skin against infection and speed up the healing process.
