Tetanus infection is quite frightening, with current statistics showing that the mortality rate of tetanus infections can be as high as 40%, and about a million people die from tetanus globally each year. The current principle is to promptly inject tetanus antitoxin or tetanus immunoglobulin for sharp, deep wounds. For tetanus infection, the main symptoms manifest as local or systemic muscle rigidity and spasms. The incubation period varies; if a tetanus vaccination has been previously administered, or depending on the infection and treatment of the wound, the severity of the onset can differ. The prodromal period typically presents symptoms like dizziness, headache, heightened reflexes, restlessness, and possible difficulty opening the mouth; during the convulsive phase, there is continuous muscle contraction, eventually causing persistent spasms in the diaphragm and intercostal muscles.
