"collects information from 50 US states, the District of Columbia, and 5 other US territories to provide the most comprehensive testing data we can collect for the novel coronavirus, SARS-CoV-2.

"Our model is designed to be a planning tool, and is informed by the shape that other COVID-19 outbreaks are taking, in terms of deaths, around the world and across the US. Other models may use other approaches, such as assuming a population where everyone was equally likely to interact with everyone else, and model different scenarios such as the absence of, or different levels of, social distancing. These models are useful for motivating action to prevent such worst-case scenarios, while our model is designed to specifically address the planning needs of hospital administrators and local governments."
