CDC (US) just added Vietnam to level-4 very high risk countries to avoid traveling to. They are warning Americans not to travel to Vietnam because there are over 100,000 new daily cases and more than 500 cases per 100,000 people over the last 28 days which classifies it as a level-4 very high risk destination. I still think many Americans will travel to Vietnam but I don't know how that will work when Vietnam requires travel insurance that covers $10,000 and most insurance companies don't cover for level-4 very high risk countries. Vietnam should drop that requirement or make testing optional to its people.
By the way, there are currently 140 countries that are level 4 very high risk including South Korea, Japan, etc.
I believe daily cases in America (and other countries not on the level 4 list) are actually more than Vietnam. It's just that Vietnam is testing its citizens and reporting it more rigorously than Americans. Also, Americans are testing at home now and those cases are not reported at all. Just a few weeks ago, the US had more than 300,000 cases per day but after sending at home test kits to everyone, the numbers declined drastically. Maybe Vietnam should follow a similar Covid-19 testing protocol:
1. make testing optional
2. send free home test kits to its citizens (no reporting)
This would allow Vietnam to get off the level 4 list within 30 days.
