6.} Research this virus's R0 value. Explain what this means and compare it other viruses. 7.} Once infected, it takes approximately 3 days for it to become contagious. With this information along with your researched R0 value, create a hypothetical model for the total number of cases in the USA it no preventative measures are taken, and the population is evenly dispersed. Assume an initial value of 1 person. 8.} \"Herd Immunity\" is achieved if a large enough percentage of the population contract the virus, letting their natural immunity develop antibodies, and thus making it difcult for the virus to further spread to the more vulnerable members of the population. It is estimated by some that if roughly 67% ofthe population contract a virus, herd immunity will be achieved. a. Using your hypothetical model from #7, estimate how long it would have taken the U.S. to reach herd immunity. b. What advantages can you see for letting herd immunity happen unimpeded? c. Describe reasons why most world governments did not attempt to rapidly reach herd immunity
