Objects carrying tetanus bacillus, or tissues damaged by animals, require tetanus vaccination to prevent tetanus, such as rusty nails, animal claws, animal bites, venomous snake bites, and wounds contaminated by dirt can easily lead to infection by tetanus bacillus. Tetanus is a possible condition, so after an injury, it is necessary to immediately rinse the wound with soap and water or running water to wash away the toxins, which helps reduce the chance of infection. Then thoroughly disinfect the wound with iodophor, which can also reduce infection, and go to the hospital to receive tetanus antitoxin or tetanus immunoglobulin within 24 hours to prevent the onset of tetanus. The incubation period for tetanus is generally three to seven days, but it can be longer, so it is advised to go to the hospital for an injection as soon as possible after injury, to prevent the onset of the disease and avoid serious events.
