What is tetanus?
Tetanus is an acute, sometimes fatal, disease of the central nervous system, caused by the toxin of the tetanus bacterium, which usually enters the body through an open wound. The tetanus bacteria live in soil and manure, but also can be found in the human intestine and other places.
