What does it mean that all five experts who went to Vietnam were infected with the new crown virus? A piece of news recently caught my attention. The governor of Chang’an Avenue reprinted the information disclosed by Guangxi last night that five experts who went to Vietnam were found to be infected with the new crown virus after returning to China. At present, except for one severe case who still has mild breathing difficulties, the rest of the current condition is basically stable. Sequencing and comparative analysis of the new coronavirus genome showed that the virus evolutionary branch of the five infected persons was B.1.617.2, which belonged to the variant strains circulating in India. Vietnam Express published an article “Chinese Expert Team May Be Infected in Quarantine Hotel”, arguing that Vietnam’s quarantine measures were not in place, causing Indian experts to infect Chinese experts. Chen Defu, an infectious disease expert in Vietnam, said, “There must be a problem with the quarantine measures at the hotel on Ruyue 2nd. Indians infected the hotel attendants. The patients infected by Chinese experts in Vinh Phuc province were also infected with the variant strains circulating in India. These two cases show that there are two cases. There is a relationship between people.” Experts can’t tell from the news, but looking at the scope of the investigation, I feel that it should not be medical. What does this message mean? First of all, this means that current vaccines may not be as effective for preventing Indian strains. All of our people going abroad have been vaccinated with two shots, and the time to produce antibodies has been ensured. They must have gone out during the protection period of at least half a year of the vaccine, and they must have been properly protected when they go out. If a few of the five people were infected, it might not be enough to explain the problem, but all five people were infected, and further human-to-human transmission occurred. It can be seen that the infectivity of the mutant strain has been greatly improved. This situation must be the result of exposure to a higher virus titer, and it is not just that our vaccines are not sensitive to mutant strains. After two injections of Pfizer vaccine, an American infectious disease expert in India was infected and died after taking strict precautions. This shows that the Pfizer vaccine in the United States is not necessarily effective against the Indian mutant virus. This also casts a shadow over the upgrade of vaccines. Second, a new wave of epidemics has accelerated. The World Health Organization said on the 12th that the mutated virus in India has spread to 44 countries. Nepal’s cases increased by 137% last week. The number of new crown diagnoses in Laos increased by more than 200 times within one month. 98% of new cases in Thailand were all from India. There have been many imported cases from neighboring countries in Chongqing, Zhejiang, Anhui, and other places in China. According to public reports, the confirmed imported cases of the Indian mutant virus were imported after complying with the epidemic prevention regulations. Quite strict protective measures, wearing N95 masks, goggles and gloves, and nucleic acid tests are all negative. This has added new difficulties to my country’s epidemic prevention and control, and foreign defense imports have become the focus of a new round of epidemic prevention. Finally, the new virus has higher deaths and may have a greater impact on children. Yesterday I wrote about the outbreak in Taiwan Province. The mortality rate of the new mutant virus seems to have increased. In Japan, as of May 14 local time, Japan has a total of 666,000 confirmed cases and a total of 11,000 deaths. From a geographical point of view, Tokyo and Osaka Prefecture are the most serious, both of which have now declared a state of emergency. A Japanese official said that according to the Japanese government’s statistics on deaths per million people, the number of people in Osaka Prefecture on the 5th was 19.6, far higher than 15.5 in India, 16.2 in Mexico, and 14.5 in the United States. Recently, the medical system in Osaka is on the verge of collapse, leading to a sharp increase in the number of deaths and mortality in the area. According to reports, hospital beds in Osaka are in a hurry, and the utilization rate of intensive care beds is even as high as 99%. At present, a total of 18 people have passed away unfortunately because they were not hospitalized in time. According to research in Singapore, the B1617 corona disease strain from India seems to have a greater impact on children, and it is easier to transmit between children. Therefore, Singapore announced that from May 19, all schools will change to study at home. Question: Is the vaccine completely ineffective? In fact, it is not from the current point of view. Although it seems to be effective in preventing infection of new strains in individual cases, the good news is that it is still good in preventing serious illness. According to statistics from Seychelles, a country with a relatively good vaccination situation (Source: Hanson Clinical Research), the above view is reflected. At present, 72.6% of the population in Seychelles has received at least one dose of the vaccine, and 63.9 of the population is fully vaccinated. However, according to information released by the Seychelles government, 37% of the new cases as of May 8 have been fully vaccinated. This means that the rate of virus escape is very high. According to a CNN report, Seychelles vaccinated mainly inactivated vaccines from Sinopharm (57%, mainly 10-60 years old) and AstraZeneca adenovirus produced in India (43%, over 60 years old). Of course, the situation in Seychelles is not representative of all countries. This is related to the local implementation of epidemic prevention policies and the protection of vaccines. According to a research by Stanford University: Compared with unvaccinated people, people who have been vaccinated except for the infection rate In addition, the rate of serious illness requiring hospitalization seems to be lower. I reflect on the judgment that the new crown epidemic may enter the “post-epidemic era” with the popularization of vaccines some time ago. Now I feel that human understanding of the virus is still too little and too shallow. It is still necessary to take every step prudently and solidly as our country is doing now, while still focusing on prevention and control, and gaining more time for the upgrade of vaccines, on the other hand, promoting vaccination as soon as possible. Let me tell you some good news. As long as the epidemic does not pass, the economy will not be able to recover well. The United States will release water for a day, inflation will become more and more severe, and the pharmaceutical stocks in the A-shares will perform better and better. (Recently, it has been very good), good fortune and bad fortune, the more cautious China is, the more “the scenery is unique” in China’s economy, and the better it can occupy a good position in the game.
