Guidance documents

People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms may have COVID-19: cough, shortness of breath, or difficulty breathing, fever, chills, muscle pain, sore throat, or a new loss of taste or smell. This list is not all possible symptoms. Other less common symptoms have been reported, including gastrointestinal symptoms like nausea, vomiting, or diarrhea. Please consult your medical provider for any other symptoms that are severe or concerning to you.

If you think you have been exposed to someone with laboratory-confirmed COVID-19, follow the steps below to monitor your health and avoid spreading the disease to others if you get sick.

If you are ill with COVID-like symptoms, stay home. If you are unsure of how to care for yourself or are concerned about your condition, call your health care provider for advice. If you feel you need to visit your doctor, call them first. Keep yourself separated from other people and animals in your home. Cover your coughs and sneezes and wash your hands often.

On March 28, Public Health's Health Officer, Dr. Jeff Duchin, issued a Quarantine Directive and Isolation Order to protect the health of our community and prevent the spread of COVID-19.

Isolation and quarantine is a proven public health practice for reducing the spread of disease.

  • Quarantine is for people who are not currently showing symptoms but are at increased risk for having been exposed to an infectious disease. Quarantine is for people who could become sick and spread the infection to others.

  • Isolation is used for people who are currently ill and able to spread the disease and who need to stay away from others in order to avoid infecting them.

Isolation/Quarantine and Assessment/Recovery Facilities
Isolation and quarantine sites are available to provide isolation and quarantine assistance to help residents who are not able to isolate and recovery in their own home. Examples of people who may need this assistance include people who cannot safely isolate from a family member who is elderly or medically fragile, or people experiencing homelessness. Individuals can only be placed into the King County sites after a health professional with Public Health has determined that they need isolation or quarantine.
