If the needle is added whether you will get tetanus, depends on the depth of the needle and whether the needle is clean: 1, if the needle is deep, it is easy to form an anaerobic environment in the deep part of the wound, the anaerobic environment is conducive to the growth of tetanus prevention, it is possible to get tetanus. 2, if the needle is superficial, it is impossible to form an anaerobic environment, even if there are tetanus bacteria inside the wound can not survive, only the routine The disinfection will be fine. If the needle is sterile, there is no Clostridium tetani above the needle, even if the tie is deeper, no Clostridium tetani into the wound, there will be no tetanus. If the needle is stuck deeper inside the soil, the Clostridium tetani bacteria carried on the needle may infect the wound and get tetanus.
