Many researchers have already created models with projections for COVID-19 cases, hospitalizations, intensive care unit stays, and/or deaths.
I have created a model that relies on the fact that some parts of the country are further along the growth curve of the pandemic to produce COVID-19 case projections for Illinois counties. I use data only from the 48 contiguous states, with the expectation that those states provide a better comparison for Illinois than foreign countries do. And I make no assumptions about the virus or the effects of social distancing on transmission of the virus; instead, the model’s projections are based only on the actual data from the 48 states.
