Dear Provider,

The Sonoma County Department of Health Services has issued a Health Alert as a result of changing case definition, infection control guidelines and travel restrictions related to the 2019 Novel Coronavirus.

The case definition includes any individual presenting with fever or signs of lower respiratory illness with close contact with confirmed cases of 2019 n-CoV, as well as those with a history of travel within 14 days of symptom onset to mainland China. Human to human transmission, with and without symptoms, has been confirmed, leading to enhanced infection control guidance from the CDC.  Patients who meet the case definition should be isolated and healthcare personnel should use standard, contact, and airborne precautions, including eye protection.  Report immediately to Sonoma County Public Health Disease Control.

As of January 31 there are 9,776 confirmed cases worldwide, the majority in mainland China, of whom 213 were fatal. Seven cases in the U.S., including three in California, has been confirmed. At least 241 persons have been under investigation for illness in the US. There are no confirmed cases in Sonoma County. 

The World Health Organization (WHO) declared the outbreak of 2019-nCoV a Public Health Emergency of International Concern (PHEIC). The CDC issued a Level 3 travel warning, recommending that individuals avoid all nonessential travel to China. The Health and Human Services Secretary announced on January 31 that the coronavirus has been declared a public health emergency in the U.S., prompting new travel policies that go into effect February 5 aimed at interrupting disease transmission from travelers.

Please refer to the following more information.

Thank you for your attention to this matter.
