6. (2 matky) Run the model with valees, V=500,3=0.02,=0.2 and 7=0.1. How many people have become, or are currently, sick by dny 20 ? On what diy does the ephidemie peak? SIR With Simple Demographics 7. 11 mark| What is the equation that describes R0 for this model? 8. 2 marks How does bost lifespan affect P0 ? 9. 12 marles Suppose there is a cclased population" with no birthe of deathy or rocovery. Could this population support an endemic disease? 10. 2 marksj If the time scale for this model be davx, what might a rowcnable value for the birth/death rite d be, if we're thinking about Europeat Rabbits? (remember average lifespan =1/d ). You may suppose that the average lifespan of a European Rabbit is 9 years COVID-19 It is estimated that on average it takes 2.5 dnys fot sormene exposed to COVID-19 to become infections. Once infectious, people remain infectious for approcimately 6 days: R0 has been estimated to be 2,3 in Toronto. Suppone it is March 2020 and a single infected person arrivs at the Toronto lnternational Airport. Axsume that the population of Toronto is 2,980,000. Assume there are no interventions in place. 11. [I mark) Which model (of the three explored above) best describes this procend? 12. [2 markon ] Using. R0, find the trinsmitsion rate, $, fot COVID-19 in Toronto..
