Calculating Incidence versus Prevalence The picture represents 10 new cases of illness over about 15 months in a population of 20 persons. Each horizontal line represents one person. The down arrow indicates the date of onset of illness. The solid line represents the duration of illness. The up arrow and the cross represent the date of recovery and date of death, respectively. The picture New: Cases of Illness from October 1, 2004–September 30, 2005 Question: Calculate the period prevalence from October 1, 2004, to September 30, 2005. The numerator of period prevalence includes anyone who was ill any time during the period. In Figure 3.1, the first 10 persons were all ill at some time during the period.
Questions 61 - 63 are based on the following information. The following equation is an epidemiological model for diseases such as measles or flu describing the factors that are expected to affect disease spread rate (R.) in a population: Ro = BS/y B = the infection rate (describes how infectious a disease is); y = the recovery rate (describes how fast can an infected person recover); S = Population density of susceptibles (suscptibles are individuals without immunity to the specific pathogen) 61. What type of a model is this? a. Verbal b. Mathematical C. Statistical d. Simulation 62. According to this model, what is the effect of Population density of susceptibles on disease spread rate? Disease spread rate increases with increasing density Disease spread rate decreases with increasing density Disease spread rate is not affected by increasing density Impossible to know а. b. c. d. 63. According to this model what is the effect of host recovery rate on disease spread rate? Disease…
