Omickron is raging in my country, and many cities have entered the peak of infection.
There are more and more "yang people" around us, and "yin people" are becoming rare.
In the United States across the ocean, Omickron's new variant "Hellhound" is also rapidly siegeing cities and plundering the land.
U.S. Centers for Disease Control and Prevention said that the number of confirmed cases of new coronavirus in the United States has begun to rise. Among the cases of infection last week, 76% of the new Omickron strain "Hellhound" BQ.1.1, BQ.1 and XBB.
BQ.1.1 is a sub-branch of BQ.1, the sub-branch of BA.5.2 and BF.7, which are rampant in my country, are also sub-branches of BA.5.
Current research believes that the Hellhound may be more contagious and has more advantages in immune escape, posing a serious threat to the existing vaccine and posing a challenge to the existing monoclonal antibody therapies.
Because Pfizer and Modena's bivalent vaccines cannot efficiently neutralize the Hellhound strain, even the updated vaccine is only slightly better.
, and almost all monoclonal antibody therapies on the market have failed.
Due to the increasing number of reported cases, he is worried that the Hellhound will cause a new wave of epidemics in the winter. In addition, 10% of the deaths in the United States last week were caused by the new crown, influenza and pneumonia , which is far higher than the average level during this period of each year, resulting in a shortage of cold medicines, hospital emergency rooms are overcrowded, and the national medical system is overwhelmed.
White House announced last Thursday that it would restart the new coronavirus testing program for the family and send 4 test reagents to each family for free again.
Fortunately, although the hellhound is slightly contagious and it is almost impossible to avoid infection after being vaccinated, it is still effective in preventing severe hospitalization and death.
Data released by the U.S. Centers for Disease Control and Prevention on Friday found that the updated vaccine can reduce the risk of severe illness of new strains by 50% or more, and is 84% effective in preventing hospitalization for people over 65 years of age.
However, the proportion of people who received reinforcement injections in the United States is still very low, only 14% of the eligible population, and only 36% of those over 65 years old.
and are not optimistic about treatment.
Starting from December 2021, the United States will mainly use Pfizer's new crown drug Paxlovid therapy to treat high-risk patients, reducing the hospitalization rate by about 50%. New research from the
laboratory confirmed that the drug is still effective for Hellhounds, yet 60% of people who meet the Paxlovid use have not been able to obtain treatment, which could lead to more additional deaths.
It seems that the new coronavirus is still unwilling to calm down. Although its toxicity continues to decrease, it is still trying to fight against humans by evolving itself to become more contagious.
Will the hellhound be its last crazy? Or will it evolve new variants in the face of this last feast in China? No one knows
, but today I saw a well-known expert saying that the probability of a major mutation in the virus is very low, because evolution never develops in reverse. There is no problem with
, but the last sentence is completely unreliable because there is no direction for evolution, which is the most basic common sense. Scientists just judge based on experience that the virus is likely to not become more powerful.
But no matter what, since it has exploded, there is nothing to be afraid of. To bravely face the challenge, of course, the final victory will belong to us.
