There are several models available for estimating COVID-19 transmission dynamics, each with its own strengths and weaknesses. Covidestim stands out due to its real-time updating capability and its focus on providing localized estimates. It complements other models, such as the IHME model or the Imperial College model, offering a more granular view of the pandemic at the state or county level. This allows for tailored public health responses that are specific to regional needs.
