In a village with a population of 5000, 50 people get affected by a disease and 10 of the affected die. What is the case fatality rate?

Correct option is D

Case Fatality Rate (CFR) formula:
CFR=(Deaths due to the diseaseTotal affected cases)×100\text{CFR} = \left(\frac{\text{Deaths due to the disease}}{\text{Total affected cases}}\right) \times 100CFR=(Total affected casesDeaths due to the disease​)×100 =(1050)×100=20%= \left(\frac{10}{50}\right) \times 100 = 20\%=(5010​)×100=20%
Explanation of Other Options:
· (a) 10% – Incorrect, as the calculation does not match.
· (b) 2% – Incorrect, as this value is too low.
· (c) 0.5% – Incorrect, as this is far from the actual CFR.
· (d) 20% – Correct answer, as per the formula.
