Tetanus
Causes The bacteria that cause tetanus, Clostridium tetani, occur commonly in soils and in the feces of farm animals, cats and dogs. When they enter a deep flesh wound, spores of the bacteria may produce a powerful toxin, tetanospasmin, which acts on various areas of your nervous system. The effect on your nerves can cause muscle stiffness and spasms — the major signs of tetanus. When to seek medical advice See your doctor to obtain a tetanus booster shot if you have a deep or dirty wound and you haven't had a booster shot within the past 5 years. Or see your doctor about a tetanus booster for any wound if you haven't had a booster shot within the past 10 years. Screening and diagnosis Doctors diagnose tetanus based on a physical exam and the signs and symptoms of muscle spasms, stiffness and pain. Laboratory tests aren't used to diagnose tetanus.
