Tetanus is the name for an infection caused by bacteria, Clostridium tetani, that is found in dirt, soil, and manure and typically enters a person’s body through a puncture wound. Cases of tetanus are extremely rare in the United States—fewer than 30 cases are reported each year—due to the availability of a vaccine. In fact, the best way to prevent infection is to stay updated on vaccine boosters throughout one’s lifetime.
