The average incubation of the tetanus bacteria once it enters your body is 7-8 days. Symptoms may include difficulty swallowing, spasms and stiffness in your jaw muscles, stiffness in neck muscles, painful body spasms, fever, sweating, high blood pressure, and rapid heart rate. Tetanus can be treated.
Cases of Tetanus date back to the 5th century BCE. Carle and Rattone discovered tetanus in 1884. They found this by injecting pus of a human tetanus blister into animals. In 1889, Nicolair discovered that tetanus bacteria could be found in soil. Tetanus is most common in developing countries because of lack of health care, hygiene, and dirty conditions.
