The United States canceled the global travel warning, and the epidemic situation in COVID-19 improved?

The United States canceled? Four-level global travel warning? Tell the American people that the epidemic situation in some countries has improved, but some countries are still deteriorating. I hope people will travel cautiously. What is the global travel warning in the United States? Probably the United States divides the countries that allow Americans to travel in the world into one, two, three and four levels according to social crime rate, terrorist activities, civil strife and natural weather. Of course, the first level is safer and you can travel normally. Similarly, the higher the series, the greater the risk. At the beginning of the global COVID-19 outbreak, the United States issued a message to all citizens? Four-level global travel warning? . This is equivalent to the highest level of warning. The American government requires citizens to stop any travel activities and return to the United States as soon as possible. But recently the United States canceled this warning. Is it because the American epidemic has improved? Probably not. The epidemic in the United States is still the first in the world, and the United States may have let itself go. Even if the United States cancels the four-level travel warning, Americans today are regarded as dangerous virus carriers in the eyes of all countries in the world, and many countries, including China, prohibit Americans from entering the country. As for some countries that have to rely on Americans to develop their economy and make money, although Americans can enter the country, tourists from some countries such as Florida must provide their own negative test reports before entering the country. The epidemic situation of COVID-19 in the United States is still not optimistic, and the diagnosis rate and mortality rate remain high. It is very puzzling to cancel the fourth-level global travel warning at this time. Does the United States still want its people to take the COVID-19 virus to other countries? Although the United States was forced to return to work, as a result, many schools and enterprises were constantly diagnosed with the COVID-19 epidemic. This indifference to American life has disappointed many Americans. Now the United States has also cancelled the global travel warning. It can be speculated that the American government is ostensibly whitewashing the peace, but the severity of the epidemic in the United States is well known, and its behavior is objectively irrational, which is also unfavorable to other countries in the world.
