Nonetheless, modeling and forecasting the spread of COVID-19 remains a challenge. Here, we detail three regional-scale models for forecasting and assessing the course of the pandemic. This work demonstrates the utility of parsimonious models for early-time data and provides an accessible framework for generating policy-relevant insights into its course. We show how these models can be connected to each other and to time series data for a particular region. Capable of measuring and forecasting the impacts of social distancing, these models highlight the dangers of relaxing nonpharmaceutical public health interventions in the absence of a vaccine or antiviral therapies.}, year = {2020}, journal = {Proceedings of the National Academy of Sciences}, chapter = {202006520}, pages = {1}, month = {01}, issn = {0027-8424}, url = {https://par.nsf.gov/biblio/10172956}, doi = {10.1073/pnas.2006520117}, }
