Vietnamese authorities have placed an entire commune under quarantine for 14 days in connection with the coronavirus, with just over 10,000 locals affected.
"As of February 13, 2020, we will urgently implement the task of isolation and quarantine of the epidemic area in Son Loi commune", a health ministry statement said.
So far, there are 15 confirmed cases of COVID-19 in Vietnam, five of them in Son Loi commune.
Son Loi is a farming region made up of several villages.
The coronavirus arrived in Vinh Phuc after people from the province who had been in the central Chinese city of Wuhan, where the virus was first detected, returned home to Vietnam for the Lunar New Year holiday.
Health officials wearing protective suits sprayed disinfectant on vehicles at the checkpoints.
Although 10,000 people have been quarantined, only six people have actually been confirmed to have the virus. People with symptoms of the virus are not allowed to leave the country and are kept under strict supervision.
The disease then spread to her family and her neighbours, including a three-month-old baby. The virus is said to have stemmed from a group of eight workers who returned from Wuhan on January 17.
Villager Tran Van Minh told AFP that authorities had already advised residents to avoid large gatherings.
'Now we can not get out and even if we do, clients don't welcome us that much as before'. Local authorities have set up shops and provided food and face masks for residents there, the first official said.
Earlier this month, Vietnam banned all flights to and from mainland China and suspended new tourist visas for Chinese nationals or foreigners who were in China two weeks prior.
"The epidemic has significantly reduced the travel demand of domestic and global tourists in the Vietnam network", the company said, noting that passengers on domestic routes have also fallen by 20-30 percent over the past two weeks.
Vietnam declared a public health emergency over the epidemic on February 1 and banned all flights to and from China, where more than 1,300 people have died from the virus.
The virus has also had massive ramifications globally, with many countries banning travellers from China in a bid to stop people spreading the disease.
