The California Department of Public Health's new data modeling tool California COVID Assessment Tool (CALCAT) presents the following estimates from multiple sources in one location.
Please keep in mind that the accuracy of projections and estimates depends on the accuracy of assumptions and limited knowledge, which change as experts learn more about SARS-CoV-2.
- Nowcasts: Estimates of how fast COVID-19 is spreading in California and select counties.
- Forecasts: Projections of COVID-19 hospitalizations and deaths in the next 2-4 weeks.
- Scenarios: Long-term estimates of COVID-19 hospitalizations and deaths under different hypothetical scenarios, for example, fast-paced re-opening or slow-paced re-opening.
Please keep in mind that the accuracy of projections and estimates depends on the accuracy of assumptions and limited knowledge, which change as experts learn more about SARS-CoV-2.
