• A doctor’s office gives each patient a survey to complete. The results of the survey revealed that a person can suffer from allergic flare-ups up to 3 times per year with each flare-up lasting one week. Find the incidence rate for anyone in the population who suffers from allergies.

Solution

The incidence rate is the number of occurrences of new cases of a specified medical condition
per population at risk in a given time period.

Incidence Rate, IR = No of new occutences observed/ Sum of person-time at risk
Incidence Rate, IR = 3/52 (Since in year contains 52 weeks)
= 0.0577
