With Tet ending, health officials are taking steps to ensure that COVID-19 doesn't spread beyond the current hotspots in Vietnam.

VnExpressreports that anyone returning to Saigon from an infection zone following the holiday will have to isolate for 14 days and tested four times. These hotspots include the communes of Thuy An, An Sinh, Binh Duong and Nguyen Hue in Quang Ninh Province, as well as Dong Trieu town in the province.

The entirety of Hai Duong Province, which continues to report dozens of new cases on a daily basis — as of this morning, 539 cases have been detected in the province — is also included in this list. 

All arrivals, despite origin, will have to file a health report.

Elsewhere, anyone entering Hanoi must fill out a health declaration form, while Hai Phong and provinces surrounding Hai Duong have also enacted travel restrictions to ensure public safety.

Bac Ninh, home to major manufacturing facilities owned by Samsung and LG, has told workers from Hai Duong that they can only enter the province if they test negative for COVID-19 twice in advance.

Additionally, starting on February 14, health workers began randomly testing arrivals from Noi Bai, Van Don and Cat Bi airports in Hanoi, Quang Ninh and Hai Phong, respectively. The municipal Center for Disease Control will collect 200 samples per day.

From February 11-14, 6,551 samples were taken from people arriving from high-risk areas, with 6,504 of these samples coming back negative for COVID-19 so far.

The city has recorded 36 cases of community transmission since late January, largely linked to a team of baggage handlers at Tan Son Nhat. The original source of that cluster remains unknown.

All told, 719 domestic infections have been recorded nationwide since a 55-day streak without any known local transmission ended last month.
