All things considered, I think Vietnam is probably handling things better than a lot of the world has. That being said, I'm still critical of the stats. If an elderly person passes away, I would guess that there is less likely to be an autopsy done linking it to covid-19. Many parts of the world have a very different relationship with death and see it more as a natural part of life. Those deaths might not be reported as "covid" deaths and the same for people who were already struggling with health issues. Of course, this is all speculation but I think we need to take it into consideration when looking at the data critically. More testing is ultimately going to result in what looks like a higher number of cases.
