Vietnam is considered very vulnerable due to its long land borders and extensive trade with the outside world. Some cities are densely populated and have limited medical infrastructures. But Vietnam’s low-cost containment strategy has been found to be effective. In mid-June, there were only over 350 confirmed COVID-19 cases. With a total population of nearly 100 million, there were no COVID-19 deaths during the first phase of the pandemic. Notably, Vietnam was one of the first countries in the world to lift all domestic restrictions.
