Introduction:
Tetanus (Bacterium Clostridium tetani), also called as lockjaw or trismus, produces toxin which interferes with muscle contractions, is fatal by virtue of its respiratory muscle spasm1. Most commonly the spasms begin in the jaw for few minutes each time for three to four weeks2. Spasms may be so severe that bone fractures may occur3. The spasms can also affect the facial muscles resulting in an appearance called risus sardonicus. Chest, neck, back, abdominal muscles, and buttocks may be affected. Back muscle spasms often cause arching, called opisthotonos. With treatment about 10% of people who contract tetanus die1. Death can occur within four days.
