Farmers constituted the largest occupational group (43.7%), and only 2.2% had documented tetanus vaccination. Hospitalizations fluctuated but showed an overall increase, with a rising proportion of severe cases (Ablett grade III\/IV). A seasonal peak was observed in August\u2013September. The most common etiology was post-traumatic injury (43.4%). Critical care was frequently required: 25.1% of patients were admitted to the ICU, and 23.8% received mechanical ventilation. Multivariable analysis identified higher Ablett grade, injection drug use, unknown etiology, and comorbidities as independent risk factors for mortality; ICU admission was protective. Case fatality declined significantly from 11.8% in 2012 to 3.5% in 2021, while median hospitalization costs rose substantially.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This large-scale study reveals a substantial burden of severe non-neonatal tetanus among under-vaccinated adults, persisting despite the region\u2019s economic transition.
