The surge in new coronavirus cases that has alarmed health officials and put renewed strain on hospitals appears to be driven at least in part by increases in younger Californians falling sick.

As of Wednesday, 56% of people diagnosed with COVID-19 were 18 to 49 years old, though they account for only 43.5% of the state’s population. That figure has risen consistently throughout the outbreak but surged sharply in recent weeks.

The changes may be due in part to expanded testing. Early in the outbreak, it was nearly impossible to get a test for the coronavirus unless one was sick enough to be hospitalized.
