CDC Health Update and Guidance on Coronavirus (2019-nCoV)

The Centers for Disease Control and Prevention (CDC) issued a health update on February 1, 2020 about 2019-nCoV. This builds on the information provided in their initial January 17 health update on the coronavirus.


Update and Interim Guidance on Outbreak of 2019 Novel Coronavirus (2019-nCoV)


The definition of Patients Under Investigation (PUI) has been expanded with a new category: those with a history of travel from mainland China (with symptom onset within 14 days) who have fever AND lower respiratory symptoms AND require hospitalization are considered to be PUIs.

In addition, those with a history of travel from Hubei Province, China (not just Wuhan) within 14 days of symptom onset who have fever AND signs/symptoms of a lower respiratory illness are also PUIs.

The CDC message includes a flow chart to identify and assess 2019-nCoV, information on evaluation and testing, guidance for clinicians caring for patients with 2019-nCoV, and updated infection prevention and control guidance.

The Los Angeles County Department of Public Health (LAC DPH) reminds providers that PUIs should be asked to wear a surgical mask as soon as they are identified.

Patients should be placed in a private room with the door closed for evaluation, ideally an airborne infection isolation room, if available. Healthcare personnel entering the room should use standard precautions, contact precautions, airborne precautions, and use eye protection (e.g., goggles or a face shield).

Providers who see a suspect case should call LAC DPH immediately (see reporting information below).
