Dr. G explains how tetanus, caused by Clostridium tetani, can enter through small wounds—especially diabetic foot ulcers—and cause jaw stiffness, severe muscle spasms, respiratory failure, and death if untreated.

This episode covers pathophysiology, classic symptoms, incubation time, treatment (wound care, tetanus immune globulin, vaccine, antibiotics, and supportive care), and prevention: regular foot checks, wound hygiene, and staying up to date on tetanus boosters.
