We estimate the time-varying reproductive number, R[SUB]t[/SUB], a measure of transmission based on data from incident emergency department visits. Epidemic trend was determined by estimating the probability that R[SUB]t[/SUB] is greater than 1 (map below). Estimated R[SUB]t[/SUB] values above 1 indicate epidemic growth.
The second figure below shows the estimated R[SUB]t[/SUB], and uncertainty interval from November 13, 2024 through January 7, 2025 for the United States and for each reported state. (Click on the map to view the data for a specific state). While R[SUB]t[/SUB] tells us if the number of infections is likely growing or declining, it does not reflect the burden of disease.

As of January 7, 2025, we estimate that COVID-19 infections are growing or likely growing in 2 states, declining or likely declining in 32 states, and not changing in 13 states. ...

- For U.S. states, CFA and NCIRD estimate the time-varying reproductive number, R[SUB]t[/SUB]—a measure that helps quickly assess whether infections are increasing or decreasing. This helps public health practitioners prepare and respond.
