Questions 61 - 63 are based on the following information. The following equation is an epidemiological model for diseasessuch as measles or flu describing the factors that are expected to affect disease spread rate (R.) in a population: Ro = BS/yB = the infection rate (describes how infectious a disease is); y = the recovery rate (describes how fast can an infected personrecover); S = Population density of susceptibles (suscptibles are individuals without immunity to the specific pathogen)61.
