Judging from the current infectious and epidemic characteristics of new coronary pneumonia, this respiratory infectious disease is much more serious than the common influenza A and B, which is not only highly contagious, but also has a high lethal rate, and does not Changes automatically disappear. Therefore, if there is no effective control means, it is likely to exist for a long time.

According to the methods we can take at present, there are two ways to end the new crown epidemic. Any one of them can completely control the new crown pneumonia.

1. Thoroughly isolate the source of infection and cut off the transmission route.

Identify all patients with new coronary pneumonia and isolate them completely. This is the most direct way to end the new crown epidemic. Although this method is extremely difficult, China’s experience in the fight against epidemics has confirmed that this method is not unrealistic. And the determination of the people.

It can be said that if other countries can fight the epidemic like China, the new coronary pneumonia, like the "SARS" of that year, is already over.

Regrettably, China's anti-epidemic experience and the precious time window left to the world have not been valued by other countries. It has directly led to large outbreaks in many countries such as Europe and the United States, and it has become unstoppable.

So, in fact, this method is difficult to achieve.

2. The advent of the vaccine and its popularity worldwide

The vaccine is said to be the terminator of new coronary pneumonia. Although humans have not yet had specific drugs for viral infections, the development of vaccines is realistic. The smallpox virus has been circulating for thousands of years, and finally the advent of the modern vaccinia vaccine, which ended the biggest devil in human history.

China has completed the vaccination of the subjects of Phase I clinical trials of the new coronavirus vaccine at the end of March, and began recruiting volunteers for Phase II clinical trials on April 9, which is also the world’s first new coronavirus vaccine to enter Phase II human clinical trials ; On April 12 and April 13, vaccines developed by three companies in China have been approved for clinical trials. In overseas deployment, the National Research Council of Canada announced on May 12 that it will cooperate with a biological company in Tianjin, China to jointly promote the development of a new coronavirus vaccine.

"Life-saving medicine" we see the dawn, but the vaccine is not aimed at patients, but the prevention of healthy people.

In other words, only when a healthy person is vaccinated extensively and a real group immunization is established can the goal of extinction of the new coronavirus be achieved. If only a part of people are vaccinated, the epidemic situation cannot be completely controlled.

There is a problem that has to be faced. If everyone is vaccinated, what will happen to this cost? What about the poor who cannot afford the expenses? For example: in the slums of African countries and some countries in Asia, many people become a problem with meals. Compulsory vaccination and payment will become very difficult.

This question was answered at the video conference of the 73rd World Health Assembly just concluded. Regarding the new crown vaccine, the Chinese government solemnly promises that it will be used as a global public product after the new crown vaccine has been developed and put into use, and will contribute to the realization of the availability and affordability of the vaccine in developing countries.

China's responsibility as a responsible power has become the biggest highlight of this WHO conference. The successful development and mass production of Chinese vaccines and their worldwide popularization are expected to become the main force for the end of new coronary pneumonia.

Based on the above situation, if the new coronary pneumonia is to be controlled worldwide, it is not realistic to rely on complete isolation. It can only hope that the vaccine will be published and popularized. Widespread popularity cannot be achieved in a few months, and it may take a year or two, or even longer.
