Firstly, it must be acknowledged that tetanus is a curable, specific infectious disease. When the human body is infected with tetanus, the initial symptoms mainly include dizziness, headache, fatigue, decreased appetite, difficulty in chewing, muscle soreness, or some heightened reflexes. As the condition worsens, muscle spasms and rigidity can occur, such as grimacing, lockjaw, difficulty opening the mouth, stiff neck, and opisthotonos. In severe cases, there may be difficulty breathing, respiratory arrest, and even cardiac arrest. If someone is suffering from tetanus, they should promptly seek systematic and formal treatment at a hospital. As long as there are no serious complications, the vast majority of tetanus patients can be cured, so tetanus is not as frightening as it may seem.
