Question

A group of 200 individuals living in a small town have been exposed to a new viral infection that causes severe respiratory illness. Out of 200 individuals, 40 have been diagnosed with the disease over a period of 10 days. Calculate the cumulative incidence. Give number of new cases during the time period=

Total population=
time period=

Answer 1

The cumulative incidence is the number of new cases of a disease that occur in a population at risk during a specified time period.

Given:

Number of new cases = 40

Total population = 200

Time period = 10 days

To calculate the cumulative incidence, we divide the number of new cases by the total population and multiply by a factor of 100 to express the result as a percentage:

Cumulative incidence = (number of new cases / total population) x 100

Cumulative incidence = (40 / 200) x 100

Cumulative incidence = 20%

Therefore, the cumulative incidence of the new viral infection in the small town is 20%.

To calculate the number of new cases during the time period, we simply divide the number of new cases by the time period:

Number of new cases during the time period = number of new cases / time period

Number of new cases during the time period = 40 / 10

Number of new cases during the time period = 4

Therefore, there were 4 new cases of the viral infection per day over the 10-day period.
