Question

1. It is determined from a report that City A has 50 new cases of an infectious disease and City B has 150 new cases. What conclusion can be made concerning the incidence of the disease in the two populations? Explain the rational for your response.

For this case please use the following information:

Number of new cases of disease / total number of new cases of disease x 100

City A 50 new cases of an infectious disease

City B 150 new cases of an infectious disease

Total number of new cases of an infectious disease is 200

City A

50 / 200 x 100

City B

150/ 200 x 100

Give me the % for City A and for City B

Answer 1

Formula for Incidence Rate = Number of new cases/ Population st the start of the time interval

So,

For City A:

Number of new cases = 50

Population st the start of the time interval = Not given.

So,

Incidence Rate of City A cannot be calculated.

For City B:

Number of new cases = 150

Population st the start of the time interval = Not given.

So,

Incidence Rate of City B cannot be calculated.

Since Incidence Rate of City A and City B cannot be calculated, .no conclusion can be made concerning the incidence of the disease in the two populations.
