COVID-19 Emergency Resource Requests

Public Health Seattle & King County (PHSKC) and King County Office of Emergency Management (KCOEM) supports local government agencies; medical and care facilities; and other organizations within King County by procuring supplies, facilities, and personnel.

There are currently no restrictions on who can be tested for COVID-19 and commercial testing is becoming more available. Healthcare providers should test all patients with symptoms consistent with COVID-19 regardless of their age or health status and individuals who have been in close contact with someone who has tested positive for COVID-19.

Long-term care facilities are at high risk for severe COVID-19 outbreaks due to their congregate nature and vulnerable population (e.g., older adults with multiple co-morbidities).

Isolation and Quarantine & Assessment and Recovery, King County Dept. of Community and Human Services

One of the key Public Health interventions we are deploying to slow the spread of COVID-19 is the siting of Isolation/Quarantine, Assessment and Recovery, and Shelter De-Intensification facilities across the County. These facilities slow the spread of COVID-19 and minimize the strain on our local healthcare facilities to ensure the safety of the public at large.
