<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A scientist is studying the characteristics of a newly discovered infectious disease in order to determine its features. He calculates the number of patients that develop the disease over several months and finds that on average 75 new patients become infected per month. Furthermore, he knows that the disease lasts on average 2 years before patients are either cured or die from the disease. If the population being studied consists of 7500 individuals, which of the following is the prevalence of the disease?? A: 0.005, B: 0.01, C: 0.02, D: 0.12, E: 0.24,  <response>: To calculate the prevalence of a disease in a population, we need to know the number of existing cases in that population at a given point in time. The question tells us that on average, 75 new patients become infected per month. It also says the disease lasts 2 years on average before patients are cured or die. So in a steady state, there will be 75 24 1800 existing cases at any given time as new cases arise at the same rate as old cases resolve. With a total population of 7500, the prevalence is the proportion of existing cases out of the total population. 18007500 0.24.E: 0.24
