For more general information, see our Human Coronavirus page.

An outbreak of respiratory illness caused by a novel coronavirus (COVID-19) began in December 2019 in Wuhan City, Hubei Province, China.

A traveler who returned to Snohomish County from Wuhan had the first lab-confirmed case of COVID-19 in the United States.

The virus may have spread from animals to people and is spreading from person to person. Coronaviruses that spread from animals to people, like MERS and SARS, caused complex outbreaks that required comprehensive public health responses.

Current information indicates the immediate health risk from COVID-19 to the general American public is low.

Immediately report suspected cases.

Call (253) 798-6410, 24 hours a day, 7 days a week.
