COVID-19 Information

COVID-19 Health Information

COVID-19 (coronavirus disease 2019) is a disease caused by the SARS-CoV-2 virus. The Snohomish County Health Department works with our community and partners to lower the risk of COVID-19 transmission and severe illness from COVID-19.

The coronavirus disease (COVID-19) is a respiratory illness. While most people who become ill with COVID-19 can recover on their own with rest and supportive care, the disease can cause severe complications and can be fatal. It is important to know how to prevent the spread of illness, recognize the signs and symptoms, and what to do if you are exposed or if you test positive for COVID-19. For specific questions about your personal risks, symptoms or care, please contact your medical provider.

Visit Washington State Department of Health's What To Do When You Are Sick With COVID-19 or Another Respiratory Virus for more information about preventing COVID-19, exposure to COVID-19 and what to do if you have signs and symptoms of COVID-19.

Testing information can be found on the WA DOH COVID-19 Testing page.

COVID-19 Vaccine

Staying up-to-date on your COVID-19 vaccinations increases protection against the disease, as immunity from the initial vaccine series can wane over time. Updated shots also expand protection against new variants of the virus. If you've completed your initial vaccine series, please talk with your healthcare provider about when you should update your COVID-19 vaccinations.

  • For details on regarding current COVID-10 vaccine info, please see the Washington State Department of Health webpage.
  • Reminder! Don't miss your annual flu shot. COVID-19 shots and flu shots are safe to get at the same appointment. Be sure to get up-to-date on your COVID vaccines and your annual flu shot to have the best protection.  

To find a vaccine provider near you, request a community-based clinic, or learn more about other immunizations, visit our Immunizations page.

Masks

Masking is optional in most public settings. You may be asked to mask in some settings, like healthcare facilities, to follow facility policy. There are many reasons someone may choose to mask, and it remains an effective tool to help reduce spread of COVID and similar respiratory illness. 

Though local health jurisdictions have the authority to put in place mask requirements at the county level, the Snohomish County Health Department does not currently have community masking requirements in place.

Different kinds of masks are made to provide protection for certain hazards. Masks are most effective when they fit snugly over your nose and mouth. Visit CDC’s Masks and Respiratory Protection to learn more about masks.

Schools / Childcare

If your child was exposed, has symptoms of COVID-19, or tested positive, refer to Washington State Department of Health's What To Do When You Are Sick With COVID-19 or Another Respiratory Virus.

If you are a staff member from a school, refer to Washington State Department of Health's Infectious Disease Control Guide for Staff.

  • For follow-up questions for schools, we encourage you to reach out first to your school nurse. The Snohomish County Health Department team can be reached at CD-Questions@co.snohomish.wa.us or 425-339-3503.
