Following the discovery of new variants of SARS-CoV-2 (CCP virus, covi) in the United Kingdom and South Africa, recently, Brazil, the United States and Russia have also burst new strain variants that are different from those in other countries. Among them, the Brazilian variant comes from the Amazon rainforest, and Russia detected 18 variant viruses in a woman. Medical experts say that the weaker the infected person is, the higher the risk of virus mutation in the body. On 13 January, a researcher in Ohio announced that they had discovered two new variants of covi. These two variant viruses are different from those previously discovered in the UK and South Africa. According to the news released by Dr. Dan Jones, head of research at Ohio State University's Wexner Medical Center, among the two newly discovered variants, one of the mutations is related to the British variant strain. The same, but also different, the current judgment should be from the United States; the other variant contains 3 unprecedented genetic mutations and evolution, which can confirm that the variant virus is not a branch of the British and South African virus strains, and this strain spreads very quickly and has become the main virus strain spreading in the State of Columbus from the end of December last year to the beginning of January this year. At present, researchers are further studying the newly discovered variant virus in terms of the degree of local transmission and whether it will affect the effectiveness of the vaccine. According to the researchers, according to data from the Medical Center, in the past few months, new variant viruses may have occurred independently in different regions of the world. The Japanese government has previously announced that four confirmed passengers who arrived in Japan from Brazil have detected a new variant of the virus that is different from the United Kingdom and South Africa. A Brazilian researcher confirmed to the media that the new variant of the CCP virus infected by the four travelers found in Japan originated from the Amazon rainforest. The virus has spread widely in the Amazon region. According to a report by the Central News Agency of Taiwan, Felipe Naveca, a researcher at the Amazon branch of the Oswaldo Cruz Foundation, Brazil’s national research institution, said that the variant virus originating from the Amazon rainforest may have only appeared between December 2020 and January 2021. New mutations have emerged. Judging from its form, it may have greater infectious power. It is estimated that in the next few months, this variant virus will spread globally. In addition, Russian RT TV reported on 12 January that researchers from four universities and one hospital in Russia jointly published their research results on the CCP virus last week, revealing an astonishing fact: In a 47-year-old woman with lymphoma, 18 variants of the CCP virus were detected successively. Researchers’ testing and research found that two of the virus strains infected by this woman belonged to the mutant virus found in Danish mink. One was similar to the mutant virus that appeared in the UK. It has common mutations but also has its own unique characteristics. Immunologist Nikolai Kryuchkov told the Russian media “Moskovsky Komsomolets” that covi will rapidly change in patients with weakened immune systems, and its mutation rate is several times higher than that of normal people. The female patient mentioned above is the case.
