Question

The population of the city of Atlantis on March 30, 2008 was 183,000. The number of new active cases of TB occurring between January 1 and June 30, 2008 was 26. The number of active TB cases according to the city register on June 30, 2008 was 264. The incidence rate of active cases of TB for the 6-month period was:

Answer 1

`\%Rate = 0.0142\%`

Explanation:

Given

`Population = 183000`

`New\ Cases = 26`

`Active\ Cases = 264`

Required

The incidence rate

This is calculated as:

`\%Rate = (New\ Cases)/(Population) * 100\%`

`\%Rate = (26)/(183000) * 100\%`

`\%Rate = 0.0001420765 * 100\%`

`\%Rate = 0.01420765\%`

`\%Rate = 0.0142\%` --- approximated

Hence, the incidence rate is 0.0142%
