Why is the skin the largest natural barrier to infection?
As Figure 1 shows, the most comprehensive barrier is the waterproof layer of skin that covers the body’s surface. Human skin keeps most pathogens out as long as it remains intact. The speed with which a cut or graze can become infected is a reminder of the protection we normally get from our skin.
