Half of newly diagnosed coronavirus cases in Washington State are in people under 40

From the article:

Dr. Jeff Duchin, health officer for Public Health — Seattle & King County, said about a third of new infections in the county are still occurring among older people in care facilities. But it makes sense to expect the age distribution to begin skewing younger as people begin to move around more and return to work.

“The pattern in who’s getting infected over time reflects people’s behavior,” he said. “If we’re seeing a drop in age, that means younger people are doing things that place them at a higher risk of transmission compared to people who are older who might be staying home more reliably.”
