Candidate drug king Lambda, ambitions are beginning to show, why is the COVID family always coming aggressively?
I believe that everyone is no stranger to COVID-19. Its emergence in 2019 can be said to have turned the world upside down. Until now, it is still doing evil all over the world.
In China, under the correct leadership of the Party Central Committee and the joint efforts of the people across the country, we are united to fight against COVID-19. Extinguished the ambition of COVID-19 to ravage China and dealt a heavy blow to its arrogance.
Nowadays, the country is generally calm. Even the rookie poisonous king Delta some time ago has only caused some small waves in China. Of course, the title of the Poison King is not a vain name. Delta is now raging around the world. It can be said to be eyeing China. If we are careless, he may also be taken advantage of.
Recently, under the prestige of the Poison King Delta, the candidate Poison King "Lamda" has begun to spread across the world again, attempting to attack the Poison King's throne. In the past two months, Lambda has become one of the most prevalent COVID-19 strains in many South American countries including Peru, Chile, Argentina, Colombia, Uruguay, and Paraguay. The mutant strain has now spread to 41 countries.
As early as August 2020, the Lambda strain was first discovered in Peru. It was not until June 2021 that the World Health Organization issued an announcement, named "Lambda" and listed it as a mutation that "needs attention". One of the viruses.
From the emergence of Lambda to the spread and spread, it has always received widespread attention from all walks of life. Why can Lambda be so arrogant? Trying to hit the Poison King's throne in vain?
First of all, Lambda`s infectious power is stronger than the new crown virus, but weaker than Delta. At present, Delta`s infectious power is the strongest; and it may have the ability to reduce certain antibodies to neutralize the virus. This is Most importantly, because this result may cause the vaccine to fail, but there is no evidence to prove whether Lambda has this ability.
From the recent Delta and Lambda, to last year's new coronavirus, and then to the previous SARS coronavirus (SARS) and Middle East respiratory syndrome coronavirus. These are all coronaviruses. Coronaviruses can now be said to be a very large family. There are currently 7 types of coronaviruses known to infect humans, namely HCoV-229E, HCoV-OC43, HCoV-NL63, HCoV-HKU1, SARS-CoV (causing severe acute respiratory syndrome) and MERS-CoV (causing Middle East respiratory syndrome) and COVID-19 (SARS-CoV-2).
Maybe you don`t understand it very well when you see this. Let me analyze it briefly. If the seven coronaviruses that can infect people are grouped together, the first four are much weaker than the last three, and they are likely to cause some respiratory symptoms. , Similar to colds, generally do not cause death, but their infectiousness and harm are different, there are strong and weak, but it should be noted that the coronavirus is not a flu virus.
But the latter three are different. SARS-CoV (Causes Severe Acute Respiratory Syndrome), also known as SARS, I believe everyone will not be unfamiliar. People of the older generation can also be said to be impressed, causing 919 deaths worldwide and a loss of 59 billion US dollars. Among them, China It accounted for 29.9 billion U.S. dollars, which was amazing at the time. MERS-CoV (causing Middle East Respiratory Syndrome) is also famous, so I won't introduce it more.
As for this last type, COVID-19 (SARS-CoV-2), I think everyone is impressed. It is also the most severe and harmful of the seven types of COVID-19. So far, it has caused 4426816 worldwide. Human deaths cause global economic losses of 77 billion to 347 billion U.S. dollars, and this number will only increase and not decrease, and it will continue to grow.
Moreover, the recent poison king Delta and the candidate poison king Lambda are both mutant strains of COVID-19. It can be seen how powerful this COVID-19 is.
So why is the harm of coronavirus so great? And it is always menacing, and the people who beat them are caught off guard?
Viruses are very prone to mutation and mutation. I believe everyone knows it. From our point of view, we don`t care about all the mutations of the virus, but only the key point mutations, which determine the ability of the virus to infect and cause the human immune system to produce immunity. Sites, these sites are also the basis for vaccine development. If these sites never mutate, or the variability is small enough to have an impact, we don`t care about it, otherwise it will be very troublesome.
In other words, many of the mutations of COVID-19 are at these sites, which means that we need to continue to develop new vaccines. Fortunately, so far, the degree of mutation of COVID-19 is much lower than that of influenza virus, that is, the new type of coronavirus that causes the vaccine to fail will not appear very quickly.
Finally, I also believe that with the continuous development of human technology, mankind will one day defeat these viruses.
