The earliest clinical manifestations of tetanus patients, which are weakness, dizziness, headache, weakness in chewing and localized muscle tension, are not specific. After Clostridium tetani invades the human body, in the anoxic environment, the spores develop into proliferators, rapidly multiply and produce a large number of exotoxins, including spasmodic toxins that can cause contraction or spasm of the rhabdomyosin, hemolytic toxins that cause local tissue necrosis and myocardial damage. The earliest clinical manifestations of tetanus are not specific, such as fatigue, dizziness, headache, weakness in chewing, local muscle tension, etc., while the typical symptoms are persistent contraction of rhabdomyolysis, paroxysmal spasms, the order of occurrence of which is masticatory spasm, i.e., difficulty in opening the mouth; facial spasm, i.e., a bitter grinning face; and cervical muscle spasm, i.e., coracoid spasms (high degree of rectification of the collar and back, and the body curved in the form of a bow). If the above clinical manifestations occur in daily life, it is recommended to go to a regular hospital to avoid delaying the condition.
