As of Jan. 14, the US CDC maintains a "Watch-Level 1" travel health notice due to reported novel coronavirus in China.

Background and Analysis
The disease outbreak was reported on Dec. 31, 2019, as suspected Severe Acute Respiratory Syndrome (SARS) cases. However, by Jan. 7, 2020, the pathogen was isolated and identified as a new type of coronavirus (novel coronavirus, nCOV), ruling out any other respiratory pathogens such as influenza, avian influenza, adenovirus, SARS coronavirus (SARS-CoV), and Middle East Respiratory Syndrome coronavirus (MERS-CoV), as the cause. Evidence suggests that the outbreak is associated with exposures in one seafood market. The majority of cases were individuals who handled the seafood and frequent visitors to the market. Authorities closed the market Jan. 1, 2020. To date, no infection has been reported among healthcare workers, and there is no clear evidence of human-human transmission. Chinese health authorities continue with intensive surveillance and follow-up measures and epidemiological investigations.
Emphasize basic health precautions, especially frequent handwashing with soap and water, or an alcohol-based hand sanitizer if soap and water are unavailable. There is no evidence that influenza vaccine, antibiotics, or antiviral medications will prevent this disease, highlighting the importance of diligent basic health precautions.
