Study: King County needs to do more with testing, tracing

SEATTLE (AP) — A new study says a comprehensive system of testing, contact tracing and quarantines will be needed to avoid a burst of new COVID-19 infections before King County can ease social-distancing restrictions. The Seattle Times reports the study from the Bellevue, Washington-based Institute for Disease Modeling says such measures could enable economic and social activity in the region to double from current levels, without a corresponding increase in infections. But it says if King County can’t increase testing capacity, fails in its efforts to notify the close contacts of positive cases or can’t convince people to isolate if they’ve been exposed to the virus, new infections could sharply increase.
