SEATTLE - A new report out of King County tries to answer this question: Where are people contracting COVID-19? .

For the first time, King County health officials are releasing where people expect they were exposed to the virus in the weeks leading up to their illness. .

Jeff Duchin warned that they cannot always determine transmission with certainty, but most people trace likely exposure back to their own household, where 35 percent of cases may have been infected by someone else who was positive in the home. .

Duchin said hospitalizations in King County are increasing three and four-fold every day and said positive cases doubled in about two weeks.
