I 11 Variations under the surveillance of the SarsCoV2 virus and, of these, the most worrying 5, All of which are now widespread in dozens of countries around the world. There is a recent visit Epsilon, An article published in the journal Science is one of the categories that considers all intentions and purposes, which is called Vogue (Anxiety Variations). To elevate it in the rankings are the properties of its spike protein, the molecular nail that binds the virus itself to the cells, which contains three mutations that are resistant to antibodies, created by the vaccine and by ‘infection’.
Currently, the World Health Organization (WHO) and the Centers for Disease Control in the United States (CDC) include alpha, beta, gamma, and delta in the VCO group. In both lists, Epsilon is still included in the group of variants under surveillance Woi (variations of interest).
Here are the characteristics of the 5 most popular types and the level of distribution:
– Alpha (p.1.1.7), Identified in Great Britain in October 2020, quickly spread around the world, replacing the previous version SarsCoV2 virus. Compared to the latter, it spreads with more than 50% efficiency. This is the variation that currently dominates the world. Its carrier version of the E484K mutation, whose vulnerability is increasing, is being monitored. According to updated data from the last 4 weeks by Guiz, the international bank that collects footage of viruses, its prevalence in Italy is 53.5%.
– Beta (p.1.351), Identified in South Africa, this variant spreads with more than 50% efficacy compared to the original virus and is easily present among young people. In Italy, the Kisite data band has not found any new reports in the last 4 weeks.
– Gamma (P.1), Identified in Japan at the beginning of 2021 and later in Brazil, is carefully observed due to three mutations, marked with abbreviations: N501Y, E484K and K417T, involved in the virus binding activity to the Ace2 receptor in human cells. Its prevalence in Italy has been 7.3%, according to Kisite data over the past 4 weeks.
– Delta (p.1.617.2), Identified in India, quickly spread to over a hundred countries, thanks to the excellent performance of the spread, rated 50% to 60% higher than the alpha variant. It is undoubtedly under special surveillance around the world and many experts believe it could become a dominant virus, altering the alpha variant. Although its two ‘sisters’ (B.1.617.2.1 and B.1.617.2.3) are much less aggressive and now belong to the Kappa family genre, we look closely at the Delta-born AY.1 version. Very efficient at spreading.
– Epsilon (p.1.427), Identified in California, is not yet widespread in Europe and according to the international bank Kisite only two cases have been detected in Italy. Research published in science and led by Matthew McCullum of the University of Washington in Seattle suggests that this variant contains three mutations in spike protein that are resistant to antibodies. According to Kisite, only 2 cases have been detected in Italy.
