Tetanus occurs when wounds are contaminated by Clostridium tetani, which then proliferates and grows within the human body, ultimately causing tetanus. Generally, tetanus is not transmitted from person to person; it usually occurs when bacteria invade the body through external injuries or wounds. Additionally, newborns may contract tetanus through the birth canal during delivery. Therefore, for deep or large wounds, especially in heavily contaminated conditions, it is crucial to clean and possibly stitch the wounds promptly. If necessary, tetanus immune globulin injections and vaccinations against these bacteria can be administered to thoroughly prevent the occurrence of tetanus.
