Effective reproductive number (Re) reflects hospitalization data through 11/08/2021. In regions with smaller populations, reported cases are also used to generate these estimates. The prevalence of infections and percent of the population infected is estimated for 11/01/2021. Due to lags between infection and hospitalization, estimates of transmission control and the effective reproductive number represent the spread of infections through approximately 10/26/2021.

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.
