How 'overreaction' made Vietnam a virus success
Despite a long border with China and a population of 97 million people, Vietnam has recorded only just over 300 cases of Covid-19 on its soil and not a single death.
Nearly a month has passed since its last community transmission and the country is already starting to open up.
'Extreme but sensible' measures
"When you're dealing with these kinds of unknown novel potentially dangerous pathogens, it's better to overreact," says Dr Todd Pollack of Harvard's Partnership for Health Advancement in Vietnam in Hanoi.
Recognising that its medical system would soon become overwhelmed by even mild spread of the virus, Vietnam instead chose prevention early, and on a massive scale.
By early January, before it had any confirmed cases, Vietnam's government was initiating "drastic action" to prepare for this mysterious new pneumonia which had at that point killed two people in Wuhan.
