Risk factors
By Mayo Clinic staffIn addition, certain factors are necessary for tetanus bacteria to proliferate in your body. These include:
- Lack of immunization or inadequate immunization — failure to receive timely booster shots — against tetanus
- A penetrating injury that results in tetanus spores being introduced to the wound site
- The presence of other infective bacteria
- Injured tissue
- A foreign body, such as a nail or splinter
- Swelling around the injury
Tetanus cases have developed from the following types of injuries:
- Puncture wounds — including from splinters, body piercings, tattoos, injection drugs
- Gunshot wounds
- Compound fractures
- Crush injuries
- Burns
- Surgical wounds
- Ear infections
- Dental infections
