Does the child head knock need to hit tetanus

Tetanus is a disease caused by Clostridium tetani invading the body through skin or mucosal wounds, growing and reproducing in an oxygen-deficient environment to produce toxins, causing spasms. Therefore, whether to inject tetanus antitoxin depends on the depth of the wound and the degree of contamination. If only the epidermis is cut and relatively clean, tetanus antitoxin injection is not required, but it should be cleaned and disinfected. If the wound is deeper and hit a dirty place, it should be injected with tetanus antitoxin, and the local area should be cleaned, disinfected and sutured.
