Tetanus is a curable disease. It is usually caused by an infection with the tetanus bacillus, which produces a specific infection in the human body. Clinically, it is mainly manifested as muscle tension and rigidity, with the primary symptoms being difficulty opening the mouth, a sardonic smile, neck stiffness, and opisthotonos. In severe cases, it can lead to respiratory confusion, respiratory arrest, or cardiac arrest. Therefore, patients with tetanus should go to the hospital for treatment as soon as possible. With standardized and systematic treatment, the vast majority of patients can be cured.
