Tetanus is usually a specific infection caused by Clostridium tetani in the human body. In the early stages of tetanus, it mainly manifests as dizziness, headache, fatigue, decreased appetite, weak chewing, some muscle soreness, or increased muscle reflexes. As the condition worsens, muscle spasms and rigidity may occur.

During a tetanus attack, symptoms mainly include lockjaw, difficulty opening the mouth, a sardonic smile, stiffness in the neck, opisthotonus, and in severe cases, difficulty breathing, respiratory arrest, or cardiac arrest. When a tetanus attack occurs, it is imperative to go to the hospital for treatment timely. Through standard treatment and care, most cases of tetanus can be cured if there are no particularly severe complications.
