50 people are suffering from cholera in a population of 5000. Out of 50, suffering from cholera, 10 died. But the total deaths are 50. What is the death rate?

**Core Concept**
The question tests the understanding of **death rate**, which is the number of deaths per 1000 people per year, and **case fatality rate**, which is the proportion of deaths within a designated population of people with a particular condition.

**Why the Correct Answer is Right**
To calculate the death rate, we use the formula: (total number of deaths / total population) * 1000. In this scenario, the total number of deaths is 50, and the total population is 5000.

**Why Each Wrong Option is Incorrect**
**Option A:** This option might be calculating case fatality rate rather than death rate.
**Option B:** This might be an incorrect calculation or misunderstanding of the formula.
**Option C:** This could be a miscalculation or incorrect application of the death rate formula.

**Clinical Pearl / High-Yield Fact**
The death rate is an important **epidemiological measure** that helps in understanding the severity of a disease in a population.

**Correct Answer:** D. 10

✓ Correct Answer: D. 10 per 1000
