Tetanus

Tetanus is a serious bacterial infection that affects the nervous system and causes muscles throughout the body to tighten. It’s also called lockjaw because the infection often causes muscle contractions in the jaw and neck. However, it can eventually spread to other parts of the body.

Tetanus infection can be life-threatening without treatment. Approximately 20 percent of tetanus infections are fatal.

Tetanus is a medical emergency that requires immediate treatment. Fortunately, tetanus is preventable through the use of a vaccine. However, this vaccine does not last forever. Tetanus booster shots are needed every 10 years to ensure immunity.
