First, in the early days of the epidemic, the American government did not treat the epidemic correctly, but used it as a means of political game, and the people did not pay much attention to it. Then the epidemic spread in the United States, and at this time the United States also developed a vaccine. Although the cooperation of the American people was not high at that time, the vaccine mutated and Omicron broke out. Although the number of infected people is rising, the mortality rate is decreasing. It is generally believed that life has returned to normal.
The second is because of American practice. As we all know, the epidemic led to the economic downturn in the United States, and then the United States began to find ways to distribute relief funds, and most people got government relief funds. This has also delayed people's urgent desire to work to a certain extent, and once they enter the working environment, the risk of infection will increase. Generally speaking, although the American people are calm at present, we all know that the epidemic is different from ordinary viruses. Once infected, the consequences are unimaginable, so we must pay attention to prevention.
