The World Health Organization (WHO) has classified a new variant of SARS-CoV-2 called<\/span> B.1.1.529 <\/span>as a \u2018<\/span>variant of concern<\/span><\/a>\u2019. <\/span><\/p>\n This variant has been named as Omicron<\/strong>.<\/span><\/p>\n The new variants of Covid-19 are detected through whole<\/span> genome sequencing <\/span><\/a>of samples that have tested positive for the virus. This process involves checking every sequence obtained for differences compared to what we know is circulating in the world. When we see multiple differences, we investigate further to confirm what we\u2019ve noticed.<\/span><\/p>\n Based on this method, the Omicron variant was first detected in South Africa. The variant has now spread to many nearby countries.<\/span><\/p>\n The Omicron Variant might have evolved during a chronic infection of an immunocompromised person, possibly in an untreated HIV\/AIDS patient.<\/span><\/p>\n Omicron Variant carries certain mutations that are concerning. They have not been observed in this combination before, and the spike protein alone has over 30 mutations.<\/span><\/p>\n This is important, because the spike protein is <\/span>responsible for the virus\u2019s entry in human cells, and it also<\/span> makes up most of the vaccines.<\/span><\/p>\n Moreover, the mutations are also <\/span>associated with more efficient cell entry, indicating enhanced transmissibility.<\/span><\/p>\n Source:<\/b> This post is based on the following articles<\/span><\/p>\n \u201c<\/b>Why this new Covid strain ‘B.1.1.529’ is more lethal that Delta variant<\/b>\u201d <\/b>published in <\/span>Business Standard <\/b>on 27th Nov 2021<\/b><\/p>\n \u201c<\/b>The hunt for coronavirus variants: how the new one was found and what we know so far<\/b>\u201d <\/b>published in<\/span> Down To Earth <\/b>on 27th Nov 2021.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":" What is the news?
