More dangerous! Delta has not been solved, the new mutant virus has spread to Japan, and the who has issued a warning.After the discovery and rapid expansion of COVID-19, people all over the world fought to fight the virus. In the end, many countries have returned to normal. Of course, some countries have been living in a deep fear of the virus for a long time due to the poor effect and inadequate measures.


However, just as COVID-19 has not yet achieved thorough control, there is a delta virus. When people have not thoroughly studied the virus, it is more dangerous to come out with a new variant virus. This undoubtedly makes it more difficult for people to fight the virus. The virus has spread to Japan, and the who has issued a warning about the emergence of the virus.


The new mutant virus spread to Japan

Novel coronavirus pneumonia has also been reported in Japan. The situation in Japan has also been in a bad situation. Up to the beginning of September, more than 20 thousand people had been newly diagnosed and confirmed by Japanese authorities. The number of patients diagnosed with new crown pneumonia in has exceeded 1 million 650 thousand.


With regard to the extremely high number of newly diagnosed new crown patients and severe patients in Japan every day, the Ministry of health, labor and welfare of Japan believes that there is a very important alert state in domestic medical treatment, and this situation can not be eliminated even to the limit. According to the estimate of the Japan Institute of infectious diseases, more than 90% of the newly diagnosed patients in August were infected by the delta variant strain with higher infection level. However, when the “delta” virus has not been solved and the number of infected cases in Japan continues to increase, a new mutant virus has spread to Japan.


new mutant virus


According to the report, Japan’s Ministry of health and labour announced that in the first few months, two Japanese patients were confirmed to be infected with the new crown virus, which was actually infected with the mutated strain “Miao”, which was also the first Japanese infected with the new type of virus.


In fact, the “Miao” virus was first found in Colombia in January 2021. At the same time, more serious outbreaks induced by this kind of virus have also appeared in countries in South America and Europe. Although the global prevalence rate of this virus is less than 0.1%, the deeper danger that this kind of virus may cause can not be ignored. In view of the many unknowns of this kind of virus, who has taken necessary measures to prevent it.


Prior to that, the World Health Organization’s weekly communiqu tion of the new crown epidemic showed that the new mutant “Miao” is highly likely to have high vaccine tolerance and evade the immunity caused by past infection and vaccination, which is listed as an “interested mutant” by the WHO and further monitoring and control of the virus.


Delta virus has not been resolved

According to the WHO guidelines, the “variant of interest” they define is that the variant has factors that can affect the transmission ability of the virus, the severity of symptoms in the case, and genetic mutations that meet the immune escape of the virus. The meaning of the “variant of interest” is inconsistent with that of the “variant of concern”, which often means that the variant can reduce the effect of public health measures, therapies or vaccines.


But in the current situation, who has already incorporated 4 variants of COVID-19 into the “attention variant”: “Alfa” virus, “beta” virus, “gamma” virus and “delta” virus. “Miao” virus has a serious risk that can not be ignored in terms of the severity of the disease caused to patients, and we still need to be highly vigilant.


Delta virus, which is spreading rapidly in the current range. It was first discovered by the inspectors in India in May 2020. There are two kinds of mutations in this kind of virus, that is, it has two significant characteristics of immune escape and increased infectivity. According to who’s research, the infection rate of Alfa virus is about half as high as that of the original COVID-19. At the same time, the infection of the delta virus is more than half of that of the Alfa virus.


According to the US Institute of disease control and prevention, the high infectivity of delta virus is comparable to the chickenpox virus sweeping the world in that year, and its infectivity can be higher than that of smallpox, SARS and even seasonal influenza in that year. At present, delta virus has widely existed in more than 100 countries and regions, with significant risk. Delta virus is an important factor in the significant increase of the second wave of epidemic in India. Earlier, this kind of virus variant only existed in a small part of India, but affected by many factors, this kind of virus has spread rapidly to hundreds of countries.


Immunization prevention and control has a long way to go

In Delta, the virus has not been completely controlled by local prevention and control organizations, and no relatively effective countermeasures have been obtained. The emergence of “Miao” virus has undoubtedly brought more obstacles to the development of epidemic prevention and control in the world. The appearance of COVID-19 has killed thousands on thousands of lives, and has caused countless families to be divided.


The efforts of experts from all countries have just achieved success in preventing and controlling this kind of virus. However, with the emergence of the mutant virus, the more significant transmission speed, infectivity and toxicity are much greater than the previous original virus. While shocking the scientific community, it also carried out more experiments and research, and continued to move forward on the road of trying to explore the mutant strain.
