Why is the COVID-19 outbreak difficult to control? Expert: The virus is too contagious, like a tractor chasing a BMW
Time flies and time flies. The COVID-19 epidemic has been going on for nearly 3 years. I have to admit that the COVID-19 virus has subverted everyone's cognition!
At first I thought that COVID-19 would be like SARS, and it would disappear automatically as the ambient temperature rose, but it didn't. On the contrary, the COVID-19 virus is still mutating, and its infectious power is getting stronger and stronger, which has seriously affected people's lives, and has had a profound and grand impact on society and the world!
Why is the COVID-19 outbreak so hard to control?
Experts concluded that the COVID-19 virus is too contagious, and humans are like tractors chasing BMWs! There are three main reasons:
First of all , from the perspective of disease performance, COVID-19 pneumonia is very hidden. In addition to ordinary, mild, severe and critically ill patients, there are asymptomatic infections. Symptomatic patients may be isolated and treated after seeking medical treatment, but asymptomatic infected people are infected with the COVID-19 virus, but they do not have any symptoms and are difficult to detect, so that the virus will spread silently.
Secondly , from the perspective of etiology, the COVID-19 virus is constantly mutating, and its transmissibility is getting higher and higher. Fortunately, after the virus mutates, the toxicity does not increase significantly. But after the virus strain mutates, it is more difficult to detect, and sometimes the nucleic acid test will not be found once or twice. In addition, compared with the original strain, some mutant strains can also be transmitted through feces, and the transmission routes are diversified, which also accelerates the spread of the virus to a certain extent.
Finally , it is difficult to trace the source. For example, in the recent epidemic in Zhuzhou, Hunan, a student was first found to be infected. After the epidemiological investigation, it was not found that he and his family had a history of living abroad. After several investigations, it was found that he had walked in a Behind the truck driver, it was really "I blew the wind that you blew" and was infected. The extension of the traceability time of epidemiology has also resulted in the widespread spread of the virus.
How does the COVID-19 virus affect people's lives?
You have to wear a mask when you go out: I believe this is the deepest feeling. Not wearing a mask is equivalent to not wearing clothes. Masks are already an indispensable part of daily life.
It is basically impossible to travel outside: The tourism industry, which has been greatly affected, has significantly reduced its business hours in the past three years, and the transportation industry, especially the aviation industry, hotels, and restaurants, has also been affected.
Online consumption is becoming more and more popular: live broadcasts bring goods, which makes some people make a lot of money, and even many stars have turned to the live broadcast industry. Of course, what followed was the cold winter of the real economy. In recent years, many self-employed businesses have closed their doors one after another, and even some larger companies are struggling to support them. We can look at restaurants nearby, are many closed?
- The economy of ordinary people has been severely hit: under the influence of the epidemic, work and production were suddenly stopped, and ordinary working class often did not get much wages. The paper "Analysis of the Status Quo of Residents' Quality of Life under the Pressure of the Novel Coronavirus Pneumonia Epidemic and Its Influencing Factors" pointed out that under the pressure of the COVID-19 pneumonia epidemic, most residents were in good health , but they did not live with their families, and those with low incomes and those with chronic diseases were in good health. Health needs to be improved and needs to be focused on.
In addition, students are also affected: because of the epidemic, in order to reduce gatherings, many students take classes online. The importance of medical staff has been vividly reflected during the epidemic: just imagine, without medical staff, how much harm will this epidemic bring?
Epilogue
Although the COVID-19 virus is highly infectious, its virulence may gradually decline over time, and then humans and the COVID-19 virus can coexist, just like the flu virus. I believe that one day, we will return to normal life!
