Q2 HIV 10 Points A simple model of infectious disease spread (for example, HIV) is U' = vW-mU - pu V' = qV-mV -rVW W' =rVW-mW-vW where v, m, p, q, and r are positive constants. The variables U, V, and W stand for susceptible population, infected (but not symptomatic) population, and symptomatic population (but not in that order). Q2.1 Susceptible 2 Points The susceptible population is represented by OU OV OW Save Answer02.2 Infected 2 Points The infected population is represented by OU 0V OW Save Answer 02.3 Symptomatic 2 Points The symptomatic population is represented by OU 0V OW Save Answer 02.4 Safe contact 2 Points Which coefficient in the model would you change to account for a \"safe-contact\" program that reduced the probability of infection per encounter? O 1} increases 0 1) decreases O m increases 0 m decreases O p increases 0 p decreases 0 q increases 0 q decreases O 7' increases 0 7' decreases Save Answer 02.5 AZT 2 Points Which coefficient in the model would you change to account for a drug that slowed the progression from infection to the appearance of symptoms {as AZT did for HIVKAIDS)? O '0 increases 0 1) decreases O m increases 0 m decreases O p increases 0 p decreases 0 q increases 0 q decreases O 1" increases 0 7' decreases Save
