The chance of getting tetanus from fishhook injury is generally based on the degree of the wound, and it is recommended that patients go to the hospital for relevant examinations to avoid delaying their condition. 1. Light wounds: If the wounds are superficial and minor after being injured by fishhooks, and if they are sterilized in a timely manner, the tetanus bacillus will not reproduce under normal circumstances, so the chances of getting tetanus are relatively low. It is recommended that the patient go to the hospital for sterilization to avoid later infection. 2. Heavy wounds: after being injured by fish hooks, if the wounds are deeper and the injured environment is dirty, and the wound is not cleaned and treated in time, the tetanus bacillus may invade into the body, so the chances of getting tetanus may be relatively high. It is recommended that patients must go to the hospital for tetanus immunoglobulin or tetanus antitoxin injection. The specific situation also depends on the individual’s condition, and it is recommended that the patient go to the hospital for relevant examinations in time.
