Tetanus is an acute infectious toxic disease caused by human infection with Clostridium tetani through a skin or mucous membrane wound, which grows and multiplies in an anaerobic microenvironment. Tetanus toxin mainly attacks the motor neurons in the human nervous system, and the patient often shows a bitter smile, clenched teeth, paroxysmal spasms, tonic spasms, and ankylosing spasms, etc. It mainly affects the muscle groups of the human body, including the biting muscle, dorsal spines, abdominal muscles, and limb muscles, etc. The incubation period of tetanus is usually 7 to 8 days. The incubation period of tetanus is usually 7-8 days, as short as 24 hours, and as long as several months or years. In addition, tetanus can be prevented clinically, including active immunization with tetanus toxoid injection, proper wound management, and passive immunization after the injury to prevent and reduce the incidence of the disease.
