Vietnam has closed the city of Da Nang to tourists after four new locally transmitted coronavirus were recorded, the country’s first since April.
No tourists can enter the city for 14 days and extra flights are being laid on to fly out up to 80,000 visitors.
Vietnam has been lauded as a success story of the pandemic having acted early to close borders and enforce quarantine and contact tracing.
It has recorded just over 400 cases and no deaths.
But nearly 100 days after its last locally transmitted case, four new cases emerged in Da Nang, a central coastal city popular with domestic tourists.
Prime Minister Nguyen Xuan Phuc on Monday ordered Da Nang residents to re-implement social distancing and close all non-essential services.
He said the response had to be “decisive” but that he was not yet ordering a total lockdown of the city.
