The Japanese Ministry of Health, Labour and Welfare, today informed the World Health Organization (WHO) of a confirmed case of a novel coronavirus (2019-nCoV) in a person who travelled to Wuhan, China. This is the second confirmed case of 2019-nCoV that has been detected outside of China, following confirmation of a case in Thailand on 13 January. Considering global travel patterns, additional cases in other countries are likely.
Coronaviruses are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome. 2019-nCoV is a new strain that has not been previously identified in humans.
Much remains to be understood about the new coronavirus, which was first identified in China earlier this month. Not enough is known about 2019-nCoV to draw definitive conclusions about how it is transmitted, clinical features of disease, or the extent to which it has spread. The source also remains unknown.
WHO encourages all countries to continue preparedness activities. On 10 January, WHO published information on how to monitor for cases, treat patients, prevent onward transmission in health care facilities, maintain necessary supplies, and communicate with the public about 2019-nCoV. The information includes advice on how to maintain hand and respiratory hygiene, and safe food and market practices. WHO is developing and updating this information in consultation with networks of experts across the globe.

WHO advises against the application of any travel or trade restrictions based on the information available. If travellers develop respiratory illness before, during or after travel, they should seek medical attention and share travel history with their health care provider.
