The situation with the coronavirus in the USA has relatively stabilised after the fourth wave of the pandemic, which peaked in September. The average infection rate in the USA is now in excess of 73.5 000 daily cases and the number of deaths is about 1.2 000 per day.
Meanwhile, more than 80% of the US population is vaccinated with at least one dose and 70% are fully vaccinated. The vaccine is also available in the US for non-citizens, including tourists.
