Question

n April of 2010, there was an epidemic of mumps in Any Town, a small town of 6,954 residents. On April
1, 2010 there were 3 residents who were recovering from mumps. During the month of April, an
additional 32 cases of mumps were diagnosed. In comparison, the neighboring town had only 2 new
cases of mumps during the month of April 2010.
6) Is it appropriate to say that the incidence of mumps was higher in Any Town than in the neighboring
town? Explain.
7) What was the incidence of mumps (per 1,000) in Any Town in April of 2010?
8) What was the prevalence of mumps (per 1,000) in Any Town on April 1, 2010?

9) What was the prevalence of mumps (per 1,000) in Any Town in April of 2010?
10) Consider a disease in which there is no cure. Once a person is infected, they have the disease for life.
In a population where no one moves in or out (i.e., a steady-state population), how could the
prevalence of such a disease increase over time while the incidence remains the same? Explain.

    Answer:

    6.) No, the incidence only includes the new cases.

    7.) Once a person is infected they continue to suffer until a cure is found unless there is no cure.

    8.) 2/6,954 = 0.0002876 = 0.2876 per 1000

    9.) 3/6,954 = 0.00043 = 0.4314 per 1000.

    10.) The occurrence of disease changes over time. Some of these changes occur regularly, while others are unpredictable. if the incidence of disease remains constant, but the rate of death from the disease or the rate of cure increases, then prevalence (fullness of the basin) will decline. If incidence remains constant, but the lives of prevalent cases are prolonged, but they aren’t cured, then the prevalence will rise.
