The epidemic is an emergency. When it first broke out, everyone was bound to be in a hurry, and it was the same all over the world. Everyone is trying to cross the river by feeling the stones. Relaxing controls rashly without accumulating experience is very risky and costly, and the price is too many lives. Look at the United States. As of 0:00 on December 22, 2022, Beijing time, there have been a total of 101,865,927 confirmed cases of COVID-19 in the United States, exceeding 100 million cases, and a total of 1,113,808 deaths, exceeding 1.1 million.
1.09 million people died! These lives are the price paid by the United States for not preventing and controlling the epidemic at first, and then for the sake of political correctness.
What implications does the U.S. epidemic data have for our future epidemic prevention?
This picture is divided into four small pictures, which are: the trend of existing diagnoses, the trend of new diagnoses, the trend of cumulative diagnoses, the cure rate and the fatality rate trend. From January 22, 2022 to December 27, 2022, the time span is nearly three years.
At the beginning of the epidemic, the United States had been a bystander and failed to keep up with protective measures. Unlike the country, which acted decisively, the existing confirmed data grew rapidly, much faster than the initial development of the Wuhan epidemic! On May 22, 2020, the number of confirmed cases exceeded one million, reaching 1,003,424, which stunned the whole world; on February 1, 2021, when the world had not recovered from the surprise, the number had grown to 9,911,107 cases, close to 10 million. This was no longer surprising, but horrifying!
Fortunately, the data later declined, and the existing confirmed data remained between 5 million and 10 million for more than ten months; it exceeded 10 million on December 14, 2021, reaching 10,044,267 cases; then it rose sharply in a short period of time, and in less than two months, it increased to 29,140,784 cases on February 6, 2022, close to 30 million! The data of
then dropped rapidly, to 1,151,037 cases on April 6, 2022; then it stabilized at one or two million cases, which continues until now. As of December 26, 2022, there are 1,775,176 confirmed cases in the United States. This "big steep slope" between February 6 and April 6, 2022 is very thrilling!
Why does the number of pictures increase so suddenly? Looking at Figure 2, the new trend during that period was also a "steep slope". The peak occurred on January 15, 2022, with 973,060 new cases in a single day, nearly 100,000! Figure 3 shows that following the "steep slope" of cumulative confirmed diagnoses, the cure rate also showed a "steep slope" of increase, which ensured the sharp decline in existing confirmed cases.
Figure 4 shows that the cure rate has been below 60% before September 27, 2020. With the accumulation of experience, it has gradually increased. There was a significant decline at the beginning of 2022. It should be that there were too many new cases and insufficient medical resources. The mortality rate of
has dropped from a maximum of 6% to 1.09% today. This is related to the reduction in the mortality rate of the mutation of the virus and the accumulation of experience.
Since the beginning of 2021, Europe, the United States and China have taken two completely different paths in epidemic prevention and control. China has chosen " dynamically clearing ", while Europe and the United States have generally begun to relax controls and choose to "coexist" with the virus.
You have also seen the results behind. The United States has accumulated more than 100 million infections and more than one million deaths. In China, as of 24:00 on December 23, data: A total of 397,195 confirmed cases have been reported, and a total of 5,241 deaths.
Now, in the face of new strains that are constantly mutating, the original measures can no longer be eliminated; moreover, after three years of fighting the epidemic, small and medium-sized enterprises can no longer bear it. In the end, we chose to follow the strategy of "taking small steps and never stopping" to gradually relax control.
