Tetanus is an infectious disease that can be cured. Generally, tetanus is considered to be caused by the infection of Clostridium tetani, which produces toxins. Clinically, it is mainly characterized by muscle tension and rigidity, such as lockjaw, difficulty opening the mouth, risus sardonicus, stiff neck, and opisthotonos. In severe cases, it can involve the respiratory muscles and diaphragm, causing difficulty breathing, respiratory arrest, and even cardiac arrest. When patients with tetanus receive standardized and systematic hospital treatment, and if there are no severe complications, the vast majority of patients can be cured.
