Scientists also immediately went into research on the new strain of corona virus to find a way to isolate, culture and find a way to produce a vaccine "made in Vietnam". Governments at all levels have never been put in such an urgent situation to take measures to prevent and control the epidemic. Vietnam has proactively applied a series of unprecedented epidemic prevention and control measures on a large scale. For the first time, we announce an acute respiratory infection caused by a new strain of corona virus as a Group A Infectious Disease, a global pandemic threat. This is also the first pandemic where we apply large-scale isolation measures and move towards social isolation like some countries in the world.
