What is the case-fatality rate associated with tetanus infection?

The case-fatality rate associated with tetanus infection varies based on several factors, including the patient's age, the presence of underlying health conditions, and the timeliness of treatment. However, the most widely accepted range for the case-fatality rate of tetanus infection is around 5-10%.

This figure reflects the serious nature of tetanus as a disease caused by the neurotoxin produced by the bacterium Clostridium tetani. Despite modern medical interventions, the mortality associated with untreated or late-treated tetanus cases remains quite high. The correct answer underscores the significant risk involved with this infection, emphasizing the importance of vaccination and timely medical intervention.

In contrast, the other options present higher percentages that do not accurately represent the generally accepted case-fatality rates for tetanus infection in the general population, as effective treatment and preventive measures like vaccination can greatly reduce mortality.
