Prime Minister Nguyen Xuan Phuc on January 23 dispatched an urgency note, requiring ministries to keep strict watch on arrivals at border gates and quarantine people suspected of carrying the disease.

All newly-confirmed cases are Vietnamese nationals, including two in Hanoi and three in Ho Chi Minh City.

The latest patient in Vietnam went to a mass religious gathering in Malaysia attended by roughly 16,000 Muslims.

A health official affirms that there’s no secondary transmission at Bach Mai Hospital so far.

Quarantine facilities are at full capacity due to flows of overseas Vietnamese who mostly returned from Europe, Southeast Asia and China.
