MMWR Updates: Initial Public Health Response and Interim Clinical Guidance for the 2019 Novel Coronavirus Outbreak; and Persons Evaluated for 2019 Novel Coronavirus United States, January 2020

Dear COCA Partners and Subscribers, we would like to notify you of two recently released Morbidity and Mortality Weekly Reports (MMWRs) about novel coronavirus (2019-nCoV).

The first report, Initial Public Health Response and Interim Clinical Guidance for the 2019 Novel Coronavirus Outbreak — United States, December 31, 2019–February 4, 2020 (MMWR Weekly/February 7, 2020. On February 5, 2020, this report was posted online as an MMWR Early Release.), describes 9 of the first 11 U.S. 2019-nCoV patients who were exposed in Wuhan, China. CDC expects more U.S. cases and is collaborating with multiple other federal agencies, state and local health departments, and other partners to implement aggressive measures to substantially slow U.S. transmission of 2019-nCoV, including identifying U.S. cases and contacts and managing travelers arriving from mainland China to the United States. Interim guidance is available at and will be updated as more information becomes available.

The second report, Persons Evaluated for 2019 Novel Coronavirus — United States, January 2020, takes an in-depth look at how CDC responded to clinical inquiries regarding approximately 650 persons in the United States and tested 210 for 2019-nCoV, one fifth of whom reported no recent travel-related risk but had close contact with a 2019-nCoV patient or a person under investigation for 2019-nCoV in the United States. (MMWR Early Release/February 7, 2020/69)
