COVID-19 Case Count Info

CASE INFORMATION FOR SNOHOMISH COUNTY RESIDENTS

The Snohomish Health District is providing regular updates on case counts in Snohomish County. We are committed to providing accurate information while respecting the medical privacy of those who become ill with COVID-19.

As of April 24, updates will only be posted by 2 p.m. Monday-Friday. Information received or completed over the weekend will be reflected in the Monday update.

Also, starting May 8, we are no longer providing a daily breakdown of cases and deaths at individual long-term care facilities. Total number of cases and deaths associated with long-term care facilities will be provided daily Monday-Friday, and a breakdown by individual long-term care facilities will be updated weekly.

This change in data reporting is to help prioritize time and effort for case investigation, contact tracing, and long-term planning. It also is important for our long-term care response team to be able to focus on testing and assisting at facilities with cases, and for long-term care facilities with a small number of known cases to feel confident reaching out for testing and support. 

In order to be able to look at dialing back some of our mitigation strategies, public health needs to have adequate case investigation and contract tracing capacity.

The Health District has added some temporary staff, coordinated with the state, and reassigned staff from other programs. However, it also needs to prioritize the work teams are doing. That includes the time spent downloading data and updating charts over the weekend.

Instead, the team’s limited resources will be focused on case investigations. By getting those unknown cases down closer to zero, the team will stand ready to respond to slight increases in cases that will invariably happen when mitigation measures begin to ease.

As a reminder, some high-level Snohomish County data is available in the statewide updates online at www.doh.wa.gov/Emergencies/Coronavirus

Deaths of Snohomish County Residents

The Snohomish Health District receives reports of deaths associated with COVID-19 from a number of sources. These include hospitals or healthcare facilities, other state or local health jurisdictions, the Snohomish County Medical Examiner’s Office, or through case investigations.

All death data provided are confirmed either through test results done before or after a death. There could be underlying health conditions, but COVID-19 is still considered a contributing factor. 

Note that county-level death data will likely not match numbers provided by the Washington State Department of Health or the Snohomish County Medical Examiner’s Office. We provide numbers for Snohomish County residents with deaths associated with COVID-19. If a resident died in a hospital or facility in another county, they would still be included in our numbers. Numbers can also vary based on the time of day when reports are run.
