COVID-19 Forecasts: Cases
Reported and forecasted new and total COVID-19 deaths as of June 14, 2021.
Interpretation of Forecasts of New Cases
- This week, ensemble forecasts of new reported COVID-19 cases over the next 4 weeks included forecasts from 27 modeling groups, each of which contributed a forecast for at least one jurisdiction.
- This week’s national ensemble predicts that the number of newly reported COVID-19 cases will likely decrease over the next 4 weeks, with 18,000 to 140,000 new cases likely reported in the week ending July 10, 2021.
- The state- and territory-level ensemble forecasts predict that over the next 4 weeks, the number of new reported cases per week will likely decrease in 30 jurisdictions, which are indicated in the forecast plots below. Trends in numbers of future reported cases are uncertain or predicted to remain stable in the other states and territories.
- The figure shows the number of new COVID-19 cases reported in the United States each week from April 10 through June 12 and forecasted new cases over the next 4 weeks, through July 10.
- Models make various assumptions about the levels of social distancing and other interventions, which may not reflect recent changes in behavior. See model descriptions below for details on the assumptions and methods used to produce the forecasts.
State & County Forecasts
State-level and county-level forecasts show the predicted number of new COVID-19 cases for the next 4 weeks by jurisdiction. Each forecast figure uses a different scale due to differences in the number of COVID-19 cases between jurisdictions. To aid in comparisons between jurisdictions, the ensemble plot for each location has a second axis (in grey) that shows the expected number of cases per 100,000 people. Only forecasts meeting a set of ensemble inclusion criteria are shown; further details are available here: https://covid19forecasthub.org/doc/ensemble/external icon. Plots of the state-level and county-level ensemble forecasts and the underlying data can be downloaded below.
