SEATTLE (AP) — The top public health official in Washington state’s most populous county is asking everyone to wear masks in indoor public spaces because of the rise of the COVID-19 delta variant — even if they have been vaccinated. Dr. Jeff Duchin, health officer at Public Health – Seattle & King County, made the recommendation Friday. Washington state’s top epidemiologist, Dr. Scott Lindquist, is urging people to use common sense and to try to not be in places with poor ventilation but is not issuing a statewide mask recommendation for vaccinated people.
