7. Explosive technological progress

The current measures of various countries to combat COVID-19, such as national state of emergency, lockdowns of the country and cities, self-discipline when going out, and keeping social distancing, focus on reducing and cutting off people-to-people communication to block the spread of the virus. Although the measures have achieved certain results, they cannot eradicate the virus from the root. Though the epidemic has been controlled by the strong "Zero COVID-19 Case Policy", the achievements are very weak, and any slack or loophole may trigger a resurgence. 

We must rely on the technological progress to return to a safe and secure world. At present, all countries are stepping up the research and development efforts to find wonder drugs and vaccines for COVID-19.

The pandemic has been inspiring the breakthroughs in related technologies. Human beings dare not to say that they have controlled and defeated the virus until they master effective testing methods, wonder drugs and vaccines. 

Opportunities also lie in crises. Every global war and crisis in modern society has brought a major transformation and explosive technological progress to mankind. For example, the WWII stimulated the development of the aviation industry and initiated the nuclear industry. The Cold War not only promoted the development of aerospace technology, but also laid the foundation for internet technology. The pandemic not only inspired the breakthroughs of technology but also greatly promoted the digital transformation of human society. 

While the tension brought by the pandemic is pushing forward technological progress, it may also explore new technological paths so that those overlooked in the past can stand out. For example, traditional Chinese medicine has played an excellent role in Wuhan's anti-epidemic process and won global attention. The fight against COVID-19 may become an important opportunity for traditional Chinese medicine to go global.

Ozone is also a technological option that has been neglected due to prejudice. As early as on Feb. 18, I wrote an article appealing for the attention to the performance of ozone in sterilization and advocated the use of ozone in the COVID-19 fight[23]. 

Experiments in Japan have proved that the possibility of virus transmission through droplets in a closed environment is 17.7 times more than that in a non-closed environment. Therefore, an important anti-epidemic measure of the Japanese government is to call on people to avoid going to confined spaces, densely populated places, and contacting each other closely. If we can make breakthroughs in the research and development of ozone sensors and control the ozone concentration as cheaply and freely like we did in temperature control, we are expected to solve the indoor virus infection problem in the presence of people by using ozone to sterilize and kill the virus, thus freeing people from the fear of contact. The globally concerted efforts in combating the pandemic will surely inspire huge technological progress and upgrade a large number of industries. 

8. Globalization will not stop 

Countries around the world have been cutting off international personnel exchanges and locking down cites since the global outbreak of COVID-19. Globalization has been instantly stopped. We are inundated with worries about globalization, and doubts and even opposition about metropolitanization. 

Indeed, with the further development of globalization, international personnel exchanges have been expanded. The overseas trips worldwide have surged from 400 million 30 years ago to 1.4 billion in 2018. 

Against the backdrop of globalization, metropolitanization is the extension of globalization. From 1980 to 2019, 117 cities around the world saw its population increase by more than 2.5 million people, and the increased population amounted to 630 million in total. Particularly, the number of megacities with a population of over 10 million surged to 33 from only five in 1980. And these megacities are mostly centers of international exchanges, and leaders in the world economic and political development. The population of those megacities amounts to over 570 million, accounting for 15.7% of global population. 

The virus has been spread worldwide through the dense aviation network and a large number of international personnel exchanges, making COVID-19 a pandemic. Many international metropolises with large populations and extensive international exchanges have been severely stricken by it. 

But it must be clear that the real reason for global spread of COVID-19 is not the speed and density of international personnel exchanges, but the long existing neglect towards infectious diseases among human beings.

Actually, the progress of globalization has been accompanied by the threat of spreading infectious diseases from the very beginning. From the Age of Navigation to today, human beings have been fighting against infectious diseases and paid heavy price many times during the period. But due to the achievements in suppressing infectious diseases, many countries and international organizations tended to underrate their threat.

For example, the Global Risks Report 2020 released at the World Economic Forum listed 10 possible global risks for the future 10 years and infectious diseases were not included. In the list of the ten risks of the greatest global impact, infectious diseases only ranked the last. 

Unfortunately, contrary to the prediction of the World Economic Forum, the COVID-19 pandemic brought unprecedented blows to human society at the beginning of 2020.

Most countries and regions that once experienced SARS, such as China, Singapore, South Korea, and Vietnam, have responded with measures similar to the "Zero COVID-19 Case Policy" and achieved good effects. That is probably thanks to the impressive experience of combating SARS. China has incorporated the experience of combating SARS into laws, regulations and general emergency response plans, and compiled related measures into manuals and guidebooks, which determined a quick launch of effective measures in time amid the COVID-19 outbreak and suppressed the epidemic[24].

In this sense, we do not need to be pessimistic. COVID-19 has drawn global attention and led to global investment in viral infectious diseases, which will definitely trigger an explosive technological revolution and social change. We will eventually overcome the threat from viral infectious diseases and turn the global failure to a global victory. 

The pandemic will not stop globalization and international metropolitanization, but give birth to a better globalization and healthier international metropolises after pains and sufferings.

6. Japan successfully avoided overloaded medical system as COVID-19 testing in the country can only be done after the person has gained a testing approval after medical consultations. However, limited testing has caused delayed quarantine of asymptomatic and moderate cases. Moreover, medical consultations and approval procedures before the testing also increased the work load of medical facilities.
