1 Tetanus is caused by a type of bacteria (Clostridium tetani). 2  The tetanus bacteria often enter the body through a puncture wound, which can be caused by nails, splinters, insect bites, burns, any skin break, and injection-drug sites.
The bacteria that cause tetanus can be found in soil, manure, or dust. They infect humans by entering the body through cuts or puncture wounds, particularly when the wound area is dirty. Animal bites, burns, and non-sterile injection of drugs can also lead to infection with Clostridium tetani.
