As the first COVID-19 outbreak in the United States emerges in Washington State, the city of Seattle, King County, and Washington State health officials provided the beginnings of a roadmap for how the region will address the rapidly evolving health crisis.
Health officials announced that four new cases were reported over the weekend in King County, Wash. There have now been 10 hospitalizations and 6 COVID-19 deaths at Evergreen Health, Kirkland, Wash. Of the deaths, five were King County residents and one was a resident of Snohomish County. Three patients died on March 1; all were in their 70s or 80s with comorbidities. Two had been residents of the Life Care senior residential facility that is at the center of the Kirkland outbreak. The number of cases in Washington now totals 18, with four cases in Snohomish County and the balance in neighboring King County.
Approximately 29 cases are under investigation with test results pending; a Centers for Disease Control and Prevention (CDC) team is on-site.
Speaking at a news conference March 2, officials sought to strike a balance between giving the community a realistic appraisal of the likely scope of the COVID-19 outbreak and avoiding sparking a panic.
“This is a complex and unprecedented challenge nationally, globally, and locally. The vast majority of the infected have mild or moderate disease and do not need hospitalization,” said Jeffrey Duchin, MD, health officer and chief, Communicable Disease EPI/Immunization Section, Public Health, Seattle and King County, and a professor of infectious diseases at the University of Washington, Seattle. “On the other hand, it’s obvious that this infection can cause very serious disease in people who are older and have underlying health conditions. We expect cases to continue to increase. We are taking the situation extremely seriously; the risk for all of us becoming infected is increasing. ...There is the potential for many to become ill at the same time.”
Among the measures being taken immediately are the purchase by King County of a hotel to house individuals who require isolation and those who are convalescing from the virus. Officials are also placing a number of prefabricated stand-alone housing units on public grounds in Seattle, with the recognition that the area has a large transient and homeless community. The stand-alone units will house homeless individuals who need isolation, treatment, or recuperation but who aren’t ill enough to be hospitalized.

Dr. Duchin said that testing capacity is ramping up rapidly in Washington State: The state lab can now accommodate up to about 200 tests daily, and expects to be able to do up to 1,000 daily soon. The University of Washington’s testing capacity will come online March 2 or 3 as a testing facility with similar initial and future peak testing capacities.
The testing strategy will continue to include very ill individuals with pneumonia or other respiratory illness of unknown etiology, but will also expand to include less ill people. This shift is being made in accordance with a shift in CDC guidelines, because of increased testing capacity, and to provide a better picture of the severity, scope, geography, and timing of the current COVID-19 outbreak in the greater Seattle area.
No school closures or cancellation of gatherings are currently recommended by public health authorities. There are currently no COVID-19 cases in Washington schools. The expectation is that any recommendations regarding closures will be re-evaluated as the outbreak progresses.
Repeatedly, officials asked the general public to employ basic measures such as handwashing and avoidance of touching the face, and to spare masks for the ill and for those who care for them. “The vast majority of people will not have serious illness. In turn we need to do everything we can to help those health care workers. I’m asking the public to do things like save the masks for our health care workers. …We need assets for our front-line health care workers and also for those who may be needing them,” said King County Health Department director Patty Hayes, RN, MN.

Now is also the time for households to initiate basic emergency preparedness measures, such as having adequate food and medication, and to make arrangements for childcare in the event of school closures, said several officials.
“We can decrease the impact on our health care system by reducing our individual risk. We are making individual- and community-level recommendations to limit the spread of disease. These are very similar to what we recommend for influenza,” said Dr. Duchin.
Ettore Palazzo, MD, chief medical and quality officer at EvergreenHealth, gave a sense of how the hospital is coping with being Ground Zero for COVID-19 in the United States. “We have made adjustments for airborne precautions,” he said, including transforming the entire critical care unit to a negative pressure unit. “We have these capabilities in other parts of the hospital as well.” Staff are working hard, but thus far staffing has kept pace with demand, he said, but all are feeling the strain already.
Dr. Duchin made the point that Washington is relatively well equipped to handle the increasingly likely scenario of a large spike in coronavirus cases, since it’s part of the Northwest Healthcare Response Network. The network is planning for sharing resources such as staff, respirators, and intensive care unit beds as circumstances warrant.
“What you just heard illustrates the challenge of this disease,” said Dr. Duchin, summing up. “The public health service and clinical health care delivery systems don’t have the capacity to track down every case in the community. I’m guessing we will see more cases of coronavirus than we see of influenza. At some point we will be shifting from counting every case” to focusing on outbreaks and the critically ill in hospitals, he said.
“We are still trying to contain the outbreak, but we are at the same time pivoting to a more community-based approach,” similar to the approach with influenza, said Dr. Duchin.
