After three days of a sore arm, I was fine. I know better. Tetanus is a disease that can be fatal. Eventually, the person can't get air into their lungs, their blood pressure will fluctuate, and their heart will not beat properly. When that happens the patient could die.
Treatment is available and can save the life of someone with tetanus even in very advanced cases.
However, it requires the patient be given very strong muscle relaxants and a machine may be used to help them breath. Tetanus is caused by a bacterium called Clostridium tetani . This bacterium grows in the soil. It only grows in areas of the soil that lack oxygen. Whenever oxygen is around the bacteria will die.
