Tetanus is typically caused by the entry of Clostridium tetani into the body through broken skin or mucous membranes, producing toxins that lead to a specific infection. In daily life, Clostridium tetani is ubiquitous, present in places like moist soil, rusty iron, and some bamboo sticks. When an injury occurs, if the wound is deep, it should be promptly cleaned with hydrogen peroxide and saline solution. Then, it is best to go to a hospital to receive a tetanus vaccine within 24 hours. A wound that has been vaccinated against tetanus generally does not get infected. Therefore, when there is a wound, as long as the wound is timely cleaned, contaminants or foreign objects removed, and then a tetanus vaccine administered at a formal medical institution, tetanus is not so easy to contract.
