According to edition.cnn.com, several travel restrictions between US states have been removed since the end of spring and early summer of 2021. But Covid-19 seems to not want to let go of us, if we keep in mind that there are many variants of the coronavirus. The new Delta variant wave has begun to spread more quickly and affects thousands of people around the world.
Since the start of the pandemic, from January to February 2020, the United States of America has reported over 46 million cases and over 748k deaths. In October 2021, the Centers for Disease Control and Prevention warned the population about nonessential travel for those who are not vaccinated.
