Latest wave hitting Southern California hospitals

Roseville, Calif.- The latest COVID-19 surge has been moving across the country and state at surprising speed due to the Omicron variant. Although not nearly as deadly or severe in most cases, the amount of infections continues to soar while driving up hospitalizations.

In California, we took a look at the top 36 counties with a population over 100,000. These counties represent ~98% of the state's total population. The data help us find where the latest COVID-19 surge is impacting healthcare systems around the state.
