Tetanus

Tetanus, or lockjaw, is a bacterial disease that affects the nervous system. The bacteria is found in soil, dust and manure, and enters the body through cuts or wounds in the skin. It is not transmitted from person to person. If left untreated, tetanus can cause jaw cramping, sudden, involuntary muscle tightening, painful muscle stiffness, trouble swallowing, fever and sweating, high blood pressure and heart rate.
