Risk factors

The greatest risk factor for tetanus infection is not being vaccinated or not keeping up with the 10-year booster shots.

Other factors that increase the risk of tetanus infection are:

• Cuts or wounds exposed to soil or manure
• A foreign body in a wound, such as a nail or splinter
• A history of immune-suppressing medical conditions
• Infected skin lesions in people living with diabetes
• An infected umbilical cord when a mother isn't fully vaccinated
• Shared and unsanitary needles for illegal drug use
