The entire world has been affected by the Sars-CoV-2 (Covid 19) virus. We all have felt the ramifications. If left unchecked, the virus would spread throughout the population at a consistent exponential rate. But because of certain preventative measures, climate, varying densities of the population, and other reasons, the virus does not spread overall on a perfectly exponential trend. Therefore, it would be unrealistic to model the spread of this virus from the beginning of the pandemic to now with a just a single exponential model. However, sometimes it is possible to exponentially model the growth or decline of this virus over certain smaller periods of time.6.) Research this virus's Ro 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 Ro value, create a hypothetical model for the total number of cases in the USA if no preventative measures are taken, and the population is evenly dispersed. Assume an initial value of 1 person
