Whether or not you will get tetanus if you are added by a needle depends on the depth of the needle and whether or not the needle is clean: 1. If you are stabbed deeper by a needle, it is easy to form an anaerobic environment in the deeper part of the wound, and the anaerobic environment is conducive to preventing the growth of tetanus, so it is possible to get tetanus. 2. If the needle is superficially stabbed, an anaerobic environment is not possible to be formed, and the tetanus bacteria can not survive even if there is any in the inside of the wound and it only needs to be routinely Sterilization is sufficient. If the needle is sterile, there is no Clostridium tetani on top of the needle. Even if the needle is stabbed deeper, no Clostridium tetani enters the wound and you will not get tetanus. If the needle is stuck deeper in the soil, the Clostridium tetani carried on the needle may infect the wound and cause tetanus.
