5: Benton County has hired you as a Public Health intern. Benton County has identified 62 cases (people
infected with the corona virus) among 90,000 county residents. As the County
Public Health department assume that age (60 years or older) is a critical risk factor for the virus infection,
they have investigated their residents’ demographics and found that the residents whose ages are 60 years
or older account for 15% of the County population. They also found that 30 of the 62 cases were 60 years
or older. They have asked you how the age is important in the corona virus infection. Please describe your
epidemiological study design, choose a relevant risk measure, and interpret the calculated measure to
determine the importance of age in the corona virus infection.
