👉 Tetanus, a serious but treatable bacterial infection, is caused by Clostridium tetani. It occurs when you are exposed to the bacteria in your body and experiences severe symptoms such as fever, headache, muscle pain, and a rash. This condition can be prevented with the administration of Tdap vaccine (tetanus, diphtheria, pertussis) or Tdap booster shots every 10 years for adults and certain children over 5 years old.
