During a cholera outbreak, 200 patients died out of 2000 confirmed cases. The Case Fatality Rate (CFR) is:
- A 5%
- B 20%
- C 10% ✓
- D 1%
Correct answer: C. 10%
Explanation
CFR = (Deaths from a disease / Total confirmed cases of that disease) × 100 = (200/2000) × 100 = 10%. CFR measures the severity of disease and is an indicator of prognosis; it differs from mortality rate, which uses total population as the denominator rather than confirmed cases.
