Tetanus is a specific infection caused by the invasion of Clostridium tetani through skin or mucosal wounds, leading to muscle spasms. Tetanus mainly causes damage to the respiratory tract, digestive system, and cardiovascular system. If not treated promptly, it can lead to suffocation, respiratory failure, and endanger life. Tetanus is preventable; in cases of open wounds at risk of tetanus infection, tetanus antitoxin should be administered for emergency prevention. Tetanus is widely present in feces and soil and can invade the human body through dust or direct contamination of wounds, leading to infection. Wounds that are small, deep, or heavily contaminated all require preventive tetanus vaccinations.
