Vietnam has done a great work in screening, preventing and quarantining Covid-19 suspected people.

Vietnam has been closely monitoring the disease situation at border gates, a measure that the WHO says is extremely important to prevent the disease.

Apart from the only case detected on January 17, no other infection has been found in Vietnam's south central province of Khanh Hoa.

Vietnam has responded well to the epidemic from the very outset, preventing its spread.

Hanoi is supervising 1,857 cases returning from epidemic-hit regions and isolating 336 for health watch.
