Gov. Jay Inslee on Thursday announced that people attending outdoor events with 500 or more attendees will have to wear a mask, whether vaccinated or not. The new, expanded mask mandate goes into effect on Monday.
Inslee’s order comes on the heels of similar requirements that took effect this week in King and Pierce Counties.
It also follows reports of COVID-19 cases that have been associated with recent, large outdoor events like the Watershed Music Festival at the Gorge Amphitheatre and the Northwest Washington Fair in Lynden, both in August.
Already, the Washington State Fair in Puyallup, which is underway this month, is requiring masks indoors and outdoors because of Pierce County’s requirement.
Inslee’s requirement will apply to events such as fairs, concerts and sporting events.
Last month, Oregon Gov. Kate Brown ordered people to wear masks in most outdoor public spaces, regardless of crowd size, when physical distancing isn't possible.
On August 18, Inslee announced a statewide indoor mask mandate for individuals age five and up amid rising case counts. Previously, just unvaccinated people were required to mask up in public, indoor settings.
The order came as Washington saw a record number of COVID-19 hospitalizations, breaking the previous record set in December.
That same day Inslee expanded his previous vaccine mandate to include employees working in childcare, early learning, K-12 and higher education settings. Inslee had previously ordered most state employees and health care workers to be fully vaccinated by October 18.
Inslee’s new outdoor mask requirement follows a steep jump in COVID-19 cases in Washington during July and August, driven in large part by the highly contagious delta variant. As of September 1, the state was reporting an average of 3,300 new cases a day compared to about 350 new cases per day at the end of June.
At the same time, COVID-19 hospitalizations spiked from about three a day per 100,000 people at the end of June to around 19 per day at the end of August.
There are some signs that this “fifth wave” of COVID-19 has peaked, although public health officials warn the numbers could drop off and then rise again.
According to the Department of Health, an estimated 67% of Washingtonians 12 and up are fully vaccinated.
