Wounds include cuts, scrapes, scratches and punctured skin. They
often occur as a result of an accident or injury, but surgical
incisions, sutures, and stitches also cause wounds. Minor wounds
usually aren't serious, but even cuts and scrapes require care.
To avoid infection and aid healing Serious and infected wounds
require medical attention. You should also seek attention if the
wound is deep, if you cannot close it yourself, if you cannot
stop the bleeding or get the dirt out, or if it does not heal.
