Tetanus is actually a disease caused by the tetanus bacillus, generally entering the body after mucous membrane damage. In the early stages of tetanus, there usually are no fever symptoms. Fever typically appears in the middle to late stages. Generally, it is preceded by symptoms like episodic muscle spasms or tonic spasms. During this period, the incubation period can be about one week. In this time, the patient may experience symptoms such as general fatigue, headaches, and dizziness. Under circumstances where infection is likely, it is crucial to administer tetanus antitoxin promptly to effectively prevent the disease. Since the disease's morbidity and danger increase significantly in its middle to late stages, and the likelihood of death is also relatively high.
