Because C. tetani is commonly found in soil, tetanus is more common in agricultural regions. Any break in the skin or mucous membrane can result in a tetanus infection, but wounds that are contaminated with soil or those that produce a relatively anaerobic environment are at greater risk. Wounds that produce an anaerobic environment include those with purulent or necrotic tissue, puncture wounds, burns, gunshot wounds, animal bites, and complex fractures. Drug abusers who engage in "skin popping," or subcutaneous injections, are also at risk for a tetanus infection.
