The Times reports that the United States has missed the best time to contain the Neocoronavirus, with up to one million Americans expected to be infected, according to data provided by the CDC. It is important to realize that the consequences for Americans who fail to contain the Neo-Crown virus can be very serious. Why? 1, the United States has a large obese population The United States is one of the countries with the highest obesity rate in the world. 2020 data said that the U.S. adult obesity rate is 40%, and the rate of severe obesity is 10%. “Once obese people have pneumonia, the mortality rate is much higher than non-obese people, and now the most useful way of prevention and treatment is still the person’s own immunity.” Moreover, the United States obese people we all know, a large part of the population are heavily obese, the burden on the heart and lungs is very heavy. 2, the United States has a large elderly population According to 2018 data, the United States in 2018 alone had 52 million elderly people, and the obesity rate in old age was as high as 41%. Older people’s body functions in all aspects decline, immunity is also lower, once infected symptoms are heavier. For seniors with low immunity, the new coronavirus is a battle of life and death with them. Elderly people should take epidemic prevention measures and healthy lifestyles especially seriously to improve their immunity and win the war against the new coronavirus! 3, the United States with a large population of underlying diseases The United States has a large population of underlying diseases. Dietary habits of the people at the bottom of the United States tend to be high salt, high oil, high sugar, long-term, many people’s bodies have accumulated basic diseases. With diabetes, coronary heart disease, malignant tumors or other immunosuppressive diseases, the body’s immunity will also be suppressed, it is easy to be infected by viruses. Moreover, there is a relatively high overlap with low-income people in the above three categories. Currently in the United States does not have the state to pay for the treatment, for the diagnosed patients, it is undoubtedly a disaster. And all three of these groups are among those who have a high mortality rate when infected with the new coronavirus. Once unfortunately diagnosed, either the hospitalization period is long, or the death rate is high. 4, in fact, in China, these three groups of people are also the most seriously damaged category of people in this epidemic. Although China’s current outbreak of the new coronavirus has been brought under control, but the epidemic is rampant abroad, there are still foreign students, Chinese continue to return to their home countries, in this case, the appeal of the three categories of people should continue to do a good job of protection.
