Firstly, it should be noted that tetanus is a curable specific infection. Typically, after being infected with tetanus, the early symptoms mainly include dizziness, headache, fatigue, decreased appetite, refusal of weakness, jaw pain, or some hyperreflexia.

As the condition worsens, symptoms such as muscle spasms, muscle rigidity, risus sardonicus, difficulty opening the mouth, lockjaw, opisthotonos, and stiffness in the neck can occur. In severe cases, there may be difficulty breathing, respiratory arrest, and even cardiac arrest.

The vast majority of tetanus patients can fully recover through proper and systematic treatment.
