COVID-19 Forecasts: Cases

COVID-19 Forecasts: Cases

Reported and forecasted new and total COVID-19 deaths as of June 21, 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 25 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 13,000 to 159,000 new cases likely reported in the week ending July 17, 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 26 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.

National Forecasts

National-Forecast-Incident-Cases-2021-06-21
  • The figure shows the number of new COVID-19 cases reported in the United States each week from April 17 through June 19 and forecasted new cases over the next 4 weeks, through July 17.
  • 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.

Forecast Inclusion and Assumptions

The teams with forecasts included in the ensembles are displayed below. Forecasts are included when they meet a set of submission and data quality requirements, further described here: https://github.com/reichlab/covid19-forecast-hub#ensemble-modelexternal icon.

The forecasts make different assumptions about social distancing measures. Additional individual model details are available here: https://github.com/cdcepi/COVID-19-Forecasts/blob/master/COVID-19_Forecast_Model_Descriptions.mdexternal icon

Intervention assumptions fall into multiple categories:

  • These modeling groups make assumptions about how levels of social distancing will change in the future:
  • These modeling groups assume that existing social distancing measures in each jurisdiction will continue through the projected 4-week time period:
