COVID-19 Cases by Vaccine Status

With the majority of Sonoma County residents vaccinated, the impact of the pandemic is being felt disproportionately by those who haven't been vaccinated. The county shares daily infection data broken down by vaccinated and unvaccinated residents. More cases are currently being reported among vaccinated residents because most people in Sonoma County are now vaccinated – nearly 80%. But a much larger share of the county’s unvaccinated residents are becoming infected with the virus. Unvaccinated residents are two times more likely to be infected, 16.5 times more likely to be hospitalized and 13.2 times more likely to die of COVID-19 related illness.

The last graph combines the two previous graphs, scaling the number of daily infections to show the infection rate by population size. This shows the proportional risk of infection in each group.

New COVID-19 Cases

One measure of progress is the number of new cases of COVID-19. Unchecked, infections will increase exponentially in the community with the number of newly diagnosed cases being larger each day. As social distancing and other containment measures begin to show results, the number of new cases will flatten out and eventually decline.
