The worldwide outbreak of COVID-19 (previously known as nCoV-19 or novel coronavirus) that originated in Wuhan City, Hubei Province, China in late December continues to evolve. While almost 94% of the 84,119 confirmed cases globally have occurred in China, recently more cases have been identified in countries outside China than in China. Accordingly, the Centers for Disease Control & Prevention (CDC) revised its clinical and epidemiological criteria for evaluating patients for suspected COVID-19 and subsequent testing. Currently, those revisions include expanding criteria to persons who traveled to China, Italy, Iran, Japan and South Korea to reflect ongoing community transmission in those countries.
As of Feb. 28, the Washington State Public Health Laboratory will be testing for COVID-19 six days per week, dramatically reducing burden on CDC resources and subsequent wait times for test results.
Public health continues to recommend healthcare providers consider COVID-19 in a patient who has traveled from affected geographic areas with widespread or sustained community transmission presenting with fever, cough or shortness of breath AND requiring hospitalization. Testing is restricted to the case definition criteria described below. Public health will not authorize testing for asymptomatic individuals.
For all patients:
|CLINICAL FEATURES||&||EPIDEMIOLOGIC RISK|
|Fever1or signs/symptoms of lower respiratory illness (e.g. cough or shortness of breath)||AND||Any person, including healthcare workers2, who has had close contact3 with a laboratory-confirmed4 COVID-19 patient within 14 days of symptom onset|
|Fever1and signs/symptoms of a lower respiratory illness (e.g., cough or shortness of breath) requiring hospitalization||AND||A history of travel from affected geographic areas5 (see below) within 14 days of symptom onset|
|Fever1 with severe acute lower respiratory illness (e.g., pneumonia, ARDS) requiring hospitalization and without alternative explanatory diagnosis (e.g., influenza)6||AND||No source of exposure has been identified|
|1Fever may be subjective or confirmed
2For healthcare personnel, testing may be considered if there has been exposure to a person with suspected COVID-19 without laboratory confirmation
3Close contact is defined as— a) being within approximately six feet of a COVID-19 case for a prolonged period; or b) having direct contact with infectious secretions of a COVID-19 case (e.g., being coughed on)
4Documentation of laboratory-confirmation of COVID-19 may not be possible for travelers or persons caring for COVID-19 patients in other countries.
5Affected areas are defined as geographic regions where sustained community transmission has been identified. Relevant affected areas will be defined as a country with at least a CDC Level 2 Travel Health Notice. See all COVID-19 Travel Health Notices.
6 Category includes single or clusters of patients with severe acute lower respiratory illness (e.g., pneumonia, ARDS) of unknown etiology in which COVID-19 is being considered
When to suspect COVID-19:
If above criteria are met to suspect COVID-19:

When: Thursday March 5, 11 a.m. to 12 p.m. Pacific
What: During this COCA Call, clinicians will learn what they can do to prepare for COVID-19 including identifying persons under investigation, applying infection prevention and control measures, assessing risks for exposures, optimizing the use of personal protective equipment supplies, and managing and caring for patients (inpatient and at home).
