Vietnam has detected its first locally-transmitted case of coronavirus in nearly 100 days, authorities said Saturday, in a country whose swift and full lockdown won praise for controlling the spread of the disease.

“Patient 416” is a 57-year-old retired Vietnamese man in the southern city of Danang, and the first community transmission since April 16.

Local health officials have tested 105 people who had been in close contact with him, the Ministry of Health said on its website.

The man had taken his mother to a hospital in the days before after showing symptoms of the sickness, authorities said, but gave no confirmation of how he was infected in a country where the virus appeared to have been stubbed out for several months.

“The patient is currently on ventilator support due to respiratory failure,” it said, adding his family believe his contacts with others were limited.

Despite sharing a long, ungovernable border with China, Vietnam has recorded just 416 virus cases — including the latest from Danang — with no deaths.

International flights remain strictly limited with a two-week mandatory quarantine laid out for visitors.

Some analysts say the tough response to the virus will help the economy as foreign investment and local consumer confidence bounces back. (Daily Tribune)
