Omicron mutates again!The west rejoiced, rather than worried, at doubling its infectiousness

As we all know, the spread of the more contagious omicron variant has led to a continuous increase in the number of confirmed cases in some countries, and even a tsunami of cases in some countries.The epidemic of emotional contagion also created a good environment for the virus to mutate, and sure enough, omicron mutated again in the process of transmission, this time the discovery of the omicron subtype mutant strain BA.2.Up to now, the BA.2 strain has been found in many places such as the United States and Europe.Within a matter of weeks, European officials said, the BA.2 strain had become the main circulating strain in Denmark.Some studies claim that patients infected with the BA.2 strain have even milder symptoms and are less contagious than those infected with the omicron strain, which was first discovered. However, further verification is needed to confirm whether this conclusion is correct.In addition, the WHO has made it clear that the continued spread of Omicron is likely to create a better environment for the virus to mutate, which is highly likely to occur in the future.At present, a large number of mutated strains have been found around the world, but the pathogenic rate of these mutated strains is different.Only the more virulent strains are likely to become the dominant strains, and thus become known to humans.When one of the more infectious strains spreads, it is possible that earlier strains will disappear.Given that the BA.2 strain has already appeared in many parts of the United States, it is highly likely that this subtype variant will spread rapidly in the future.In addition, according to the latest European research report, the BA.2 strain has increased in infectivity, so to speak, has doubled.But instead of worrying about the virus continuing to mutate, there is a tinge of glee and excitement in the West.Many in the West believe that omicron’s mild symptoms and increasing speed of transmission could help the world achieve herd immunity at lower cost, and that the end of the epidemic may continue to accelerate.Despite the rosy assumptions of western countries, the reality is far worse than imagined.In the United States, for example, the death toll from COVID-19 has exceeded 910,000, and the increasing death toll is even higher than that of last year during the worst of the Delta epidemic.What makes the United States even more miserable is that in addition to causing a large number of illness and death, the epidemic has also brought great pressure on the medical system, resulting in difficulties in accessing medical services and other problems, which has also led to many deaths.At present, vaccinating people as soon as possible and building a strong immune barrier are still one of the most effective ways to deal with the epidemic. It is not feasible to obtain immunity by blindly relying on infection.Part of the information reference source: huanqiu
