Below we present estimates of the true number of COVID-19 infections
in each US state on each day since March 2020. Point estimates on each day
are plotted as bold lines within 95% confidence bands.
The model used to
generate these estimates is described
We use state-level data on deaths, cases, and tests reported by the COVID Tracking Project. Our model also incorporates the results of statewide representative random sample COVID testing conducted in Indiana and Ohio.
Below are the latest infection estimates. We report point estimates with 95% credible intervals in parentheses.
