Tetanus wounds are mainly characterized by deep wound redness, accompanied by a certain degree of pain, and sometimes there is pus discharge. The incubation period is usually around seven days. After infection with Clostridium tetani, symptoms such as lockjaw and excessive arching of the back occur, which are caused by excessive muscle spasms. During the acute phase of clinical treatment, it is crucial to actively use antitoxins and antibiotics to treat the infection. Otherwise, muscle spasms may lead to paralysis of the respiratory muscles, ultimately resulting in death by suffocation. Prevention of tetanus is more important than treatment, and care should be taken to avoid injuries from rusty nails.
