Consider a population of 20 individuals. Each horizontal line in the figure below represents a person in that population who became a case of a disease for which there is no immunity, i.e., an individual can get this disease multiple times. The length of the line indicates the duration of the disease for each case. Each person became a case on the first day of the month and ended after the last day of the month. The case number is in the left-hand column. For instance, case 5 became a case of the disease for one month from March 1, 1999 until April 1, 1999. 1. What was the prevalence on May 1, 1999? 2. What was the prevalence for all of 1999? 3. What was the cumulative incidence during 1999? 4. What was the incidence density for the entire period July 1, 1998 through June 30, 2000?
