This report is generated based on hospitalization data through 02/22/2021. Due to lags between infection and hospitalization, estimates of transmission control and the effective reproductive number represent the spread of infections through approximately 02/09/2021.

Due to the small population sizes of Gilpin and Clear Creek counties, these counties are combined with Jefferson County. Jefferson County comprises 97% of the population in the Jefferson plus county cluster.
Due to lags between infection and hospitalization, the estimated effective reproductive number (Re) reflects the spread of infections approximately two weeks prior to the data of the last observed hospitalization.

Figure 5. Daily hours away from home (SafeGraph) is averaged across census block groups within the region and across the state of Colorado. The faint lines show the daily data, and the thick lines represent a smoothed average over time. The ribbon below the time away from home displays the population-weighted mean daily temperature across the state from gridMET.
