In the era when the world has entered the crown disease, it has become the first year of crown disease in 2020.Of course, this is good or bad for humans and the earth, and it is not the time to cover the coffin.
Science fiction novel trio is middot; Death eternal life proposes the concept of black domain: Since the high -level civilization in the universe will attack other low -level civilizations, and the earth is a low -level civilization, the earth must try to protect itself from attacks, and proposes to reduce the speed of light to the third system to third.The concept of cosmic speed.In this way, all the light of the solar system cannot be separated from the solar system. Other high -level civilization detects the existence of the solar system and earth civilization, and human beings will not suffer from extinction.
This fantasy is a bit like the crown disease epidemic we are facing.Crown disease has been raging in the world for more than half a year, and the number of infections and deaths is increasing, and there is no sign of ease of the epidemic.However, from the perspective of anti -epidemic experience in individual countries, the intensity of epidemic is proportional to economic activities, that is, the faster the economic activity, the faster the crown disease spreads; vice versa.Some countries have implemented strict measures to block the country, stop non -necessary economic and social activities, minimize contact with people, and successfully block the spread of coronary diseases.
It can be seen that the fight between humans and coronal viruses (SARS-COV-2) depends on the speed of economic and social activities.In the absence of special medicine and vaccine, to block virus transmission, economic and society can only maintain low speed.If the free international travel, a large number of personnel gathering in public places, people sitting in the restaurant, and other frequent communication activities, virus transmission will become difficult to curb.
For more than half a year of crown disease, scientists still uncertain the origin of SARS-COV-2; the World Health Organization believes that human beings cannot get rid of its threat for a long time in the future.There is still no special medicine for the treatment of crown diseases. The patients mainly rely on the autoimmune system and auxiliary treatment of confrontational viruses; scientists around the world are actively developing vaccines. Many of them will be available at the end of this year.Essence
However, scientists are still not sure of the effectiveness and durability of the vaccine.Generally speaking, the durability of vaccines is limited, which is not as good as the immunity developed after infection.American infectious disease experts, Fudi, said recently that the crown disease vaccine may have only five or six achievements.In other words, vaccination can only be reduced by 50%to 60%of the risk of infection.This is similar to the common influenza vaccine on the market, not as effective as measles vaccine (93%effect).Even if it is natural immunity, it is not known whether it is immune for life; a study from the King College of London, England has shown that the immunity of the crown disease after three months of healing patients has decreased significantly.All in all, the long -term effectiveness of the coronary vaccine is not optimistic, so public health and safety measures may be part of the future life.
The method of blocking SARS-COV-2 is to control the distance and exchanges between people and people. In addition, people are required to wear masks, wash their hands, and reduce gathering activities.Through these rigorous measures in some countries and regions this year, they have successfully curbed the spread of viruses. Mainland China, Vietnam, Hong Kong, Taiwan, Australia, New Zealand, South Korea, Japan, etc. are the most prominent examples.Some European countries choose to coexist with the virus, that is, not to greatly limit interpersonal distance and exchanges, maintain economic activities, allow people to naturally infection and generate immunity, and reduce the fatality of the virus during the transmission process. This is the so -called group immunity.The advantage of this strategy is that economic production has been maintained, but life and casualties have been greater in a period of time.The bigger problem is that scientists do not know how serious the virus will cause damage and sequelae to the human body.
The initial control measures in many Asia -Pacific countries and regions have achieved results, but they have paid a heavy economic price and it is difficult to restore the appearance before the epidemic, because with the frequent interpersonal contact, the case rebounds.China, Vietnam, Hong Kong, Australia, South Korea, and Japan are in the face of this situation; Australia and Hong Kong must even implement large -scale urban measures again.Even in New Zealand, which is located in the Pacific Ocean, after 102 consecutive days without community cases, Auckland suddenly added more than ten cases a few days ago. It is said that the entry freight has spread the virus.A longer -lasting negative effect is that the epidemic slows down its economic vitality and changes the office method. People have changed from face -to -face communication to highly dependent digital communication.This will promote the prosperity of digital technology in the short term, but long -term may affect the development of brain communication, creativity and science.
Now we are like driving a car that cannot brake or speed up. The transmission must be kept in the second or third gear. If it is changed to the fourth or fifth gear, the vehicle will be out of control to destroy people.What does this mean?UN Secretary -General Gutres issued a warning in July that the crown disease epidemic has brought huge financial and growth challenges to countries. Human beings may retreat for several years or even decades in terms of sustainable development.
Singapore implemented virus blocking measures in April and May of this year. The economy has shrunk by 13.2%in the second quarter, and it is expected to shrink by 5%to 7%throughout the year.Minister of Trade and Industry Chen Zhensheng said that this year's economic outlook means that the growth in the past two or three years will disappear, and we can not go back to the world before the epidemic.The growth of world economic growth will slow down, the lifestyle will greatly change, and the overall development of human civilization will also slow down.In the era when the world has entered the crown disease, it has become the first year of crown disease in 2020.Of course, this is good or bad for humans and the earth, and it is not the time to cover the coffin.
