The virus in the United States is 70% mutated, unlike the virus in China.

As of the afternoon of March 26, there were at least 82,404 new cases of viral infection in the United States, including 1,178 deaths, according to the Johns Hopkins University Real-Time Monitoring System.
in the past 24 hours or so, there have been more than 17,000 new cases and more than 250 deaths in the United States.
The United States is now the world's highest number of new cases of viral infections.
24, the total number of new cases of coronavirus infection in Los Angeles County in southern California has reached 662, of which 42 percent are between the ages of 18 and 40 and 39 percent are between the ages of 41 and 65.
is mostly young people.
as early as January, the outbreak in Wuhan, China, the first time, people do not have enough understanding of the new crown virus, has always believed that the virus is not easy for adolescents to die, after all, the original publicly diagnosed patients are generally too large, while the death of patients are basically some of their own disease of the elderly.
But then, as more and more patients appear, it is discovered that young people are equally at risk of infection, even death.
unlike most countries, young adults make up a large proportion of newly diagnosed cases in the United States.
as of 10 p.m. on March 23, 35,224 people in the U.S. had been diagnosed, but 10,000 of them were young adults. Experts say the virus in the United States may have mutated.
virus mutation is not common, in the case of SARS, after 2005, it has not been seen since, and the strains of the new coronavirus are naturally different.
it is known that today's new crown virus can be divided into two types, one is more aggressive S-type, the other is a more moderate L-type.
Type S is a relatively ancient version of the virus, closer to the bat virus, the L-type is younger, more spread and more efficient replication.
70% of the 103 viral genome studies in the United States are also L-type, which is the main reason for the high number of young adults in the United States.
but the existence of this phenomenon also illustrates a problem, perhaps the United States is the origin of the virus, it seems that only the Americans themselves know.
, after all, that's the case, only the virus in the U.S. has mutated or mutated earlier.
funny, the US media has repeatedly taunted China and demanded an apology for the global virus infection.
have to say that these media stereotypes of China are too deep, China's earliest outbreak, does not mean that China is the source of the virus.
Timely discovery and disclosure by China is responsible not only for its own country, but also for the whole world.
unfortunately, China's warning has not attracted much attention from many countries, which have to wait until the crisis has arrived, and then began to slowly come up with a response.
by virtue of such means, to make the outbreak effectively controlled is undoubtedly extremely difficult.
with the large number of people infected with the new coronavirus in many countries, is the new coronavirus a kind? The issue has previously sparked academic controversy. On the evening of March 26,
, Zhou Qi, deputy secretary-general of the Chinese Academy of Sciences and a member of the Chinese Academy of Sciences, said that the new crown virus still did not have a major mutation in China, which is not the same as abroad.
Life Times reported that Zhou Qi academician said the virus needs to survive, so mutation is the virus development is inevitable, so now there are many articles around the world describing the virus mutation.
Zhou Qi said that from China's situation, the virus mutation is not significant.
we found the virus on January 11th, measured the whole sequence, and today we have not seen any major mutations, unlike what was found in other countries in the world. On March 3,
, the National Science Review, sponsored by the Chinese Academy of Sciences, published a paper, "On the Origin and Continuing Evolution of SARS-CoV-2", which found that by analyzing the molecular evolution of the 103 new coronaviruses, the largest total genome of the new coronavirus to date, it has been found that the new coronavirus has recently produced 149 mutation points and evolved two subtypes, 101 of which belong to both subtypes.
But on March 12, the paper's communications Lu Jian researcher, Cui Jie, issued a supplementary statement, saying that the term "aggressive" in the original paper was misleading and should be replaced by a more precise term for "higher frequency" and would be corrected in the printed version of the paper.
