Information for Providers

En español

The Department of Health Services is working closely with our public health partners and healthcare providers to take action to isolate and test any high-risk individuals in consultation with the Centers for Disease Control and Prevention (CDC) to prevent the spread of disease and protect the public’s health.

County Health Officer Dr. Celeste Philip issued a health alert ( on January 31, 2020 to local health care providers and posted on the department website providing updated information about the coronavirus, California cases, and infection control guidelines from the CDC.

DHS staff will coordinate with healthcare providers to ensure that all patients with fever or other respiratory symptoms who meet criteria for testing due to recent travel to China, or contact with someone diagnosed with novel coronavirus, will remain isolated until their test results are available. The Sonoma County Disease Control team and Public Health Lab are coordinating laboratory testing with the CDC.
