There is a risk of getting tetanus after a rusty iron chip cut, but it is not a certainty that you will get tetanus, and prompt treatment such as wound cleaning is recommended. Tetanus is a disease caused by Clostridium tetani infecting a wound. The bacterium is widespread in nature and is found more often in rust. After entering the human body, if the wound is an anoxic environment, it is easier to multiply and lead to tetanus infection, such as deep wounds, small external openings, necrotic tissues inside, and blood clots filling the wound. Therefore, wounds formed after scratching with rust flakes are more susceptible to tetanus. However, it can be prevented by standardized treatment of the wound after scratching, along with tetanus vaccination, etc. The treatment of wounds includes timely and thorough debridement to prevent Clostridium tetani from reproducing. It is recommended to consult a doctor in time to avoid any delay in the treatment of the disease.
