Your investigation continues for 12 months, ending on December 31, 2013. The following table provides summary information on 12 individuals in the town. For cases, assume that onset of symptoms occurred at 12:01 am on the date of onset and recurrent disease is not possible. Assume that deaths from other causes and moves occurred at 12:01 am on the date indicated. Assume also that the 88 individuals not shown below were alive, living in YYY, and at risk of disease “X” during the entire 12 months of your investigation. Cases of Disease “X” PersonDate of OnsetOutcomeA11/29/2012Died from the disease on 1/22/2013B12/6/2012Recovered from the disease on 1/6/2013C12/23/2012Recovered from the disease on 1/14/2013D1/11/2013Died from the disease on 1/13/2013E2/5/2013Recovered from the disease on 6/18/2013F5/31/2013Recovered from the disease on 6/8/2013G9/8/2013Died from the disease on 9/18/2013H10/28/2013Recovered from the disease on 11/7/2013I12/17/2013Died from the disease on 12/29/2013Notes on other residents PersonNoteJMoved to Fargo on 3/7/2013 (lost to follow-up)KDied of another cause on 4/11/2013LDied of another cause on 7/20/2013Calculate the total person-years at risk for 2013 (show your work)Calculate the following measures of disease frequency.
