This is the second reported case in Viet Nam reporting human-to-human transmission and the first confirmed case of 2019 nCoV transmitted to a local Vietnamese individual.

Risk Assessment:
The number of confirmed cases continue to rise in China, and with the anticipated large-scale population movement over the Chinese New Year season, the risk of exportation outside of China is high. Further spread of the disease has been demonstrated, with evidence of human-to-human transmission.
WHO advice/recommendations:
WHO does not recommend any specific health measures for travelers.  In case of symptoms suggestive of acute respiratory illness either during or after travel, the travelers are encouraged to seek medical attention and share their travel history with their health care provider.
Interference with International travel or trade:

*A public health risk is something that is (or is likely to be) hazardous to human health or could contribute to a

disease or an infectious condition in humans.
