It was originally discovered in Peru in August 2020 and is currently found in 29 countries/regions. It has been designated by the World Health Organization as a “variant of interest”, and it is added due to its potential infectivity or possible resistance Add neutralizing antibodies to the list of monitored coronavirus mutations. Reported mainly in Latin America, but also found in the United States and Europe: Currently, 4 cases have been reported in Italy, and approximately 100 cases have been reported in Germany and Spain.
It is called C.37 (an alias for B.184.108.40.206) and was recently renamed “Lambda” by the World Health Organization (WHO). The World Health Organization (WHO) updated it in the latest weekly epidemiological update. named”Interested variants “(you, Interest variants) The SARS-Cov-2 coronavirus is due to “May increase infectivity or may develop resistance to neutralizing antibodies“. However, this is not a “new” variant of the coronavirus, because the first report can even be traced back to Until August 2020, When this version of the virus was first discovered in Peru’s sequencing samples.Since then, the variant has been Found in 29 countries, The prevalence rate is very high in Latin America, mainly in Chile. It was also found in the United States and Europe, and it was found in about a hundred cases between Germany and Spain.in Italy Four cases have been reported, three of which occurred within the past four weeks.
Lambda variants reported by WHO
Under the direction of “Variants of Interest”, WHO said that Lambda andHigh rate“In community transmission in several countries, with the increase in Covid-19 cases, the prevalence continues to increase.”High prevalence rates have been observed, especially in South America, in Chile (the overall prevalence rate in the recorded sequence has been detected for the first time in the region so far is 31%), Peru (9%), Ecuador (8%) and Argentina ( 2%)) “Designated by the World Health Organization.
The Peruvian author, who always points to the UN agency, reports that “81% of Covid-19 cases sequenced since April 2021 are related to the Lambda variant“And Argentina”According to the report, from the third week of February 2021 to April 2 to May 19, the prevalence has increased”, Emphasize “Accounts for 37% of the sequenced Covid-19 cases“. On the other hand, in Chile, the prevalence of the Peruvian variant has increased over time.”Represents 32% of cases sequenced in the past 60 days“The attention variants Gamma (P.1, formerly Brazilian) and Alfa (B.1.1.7, formerly British) circulate at a similar speed.
Characterizing the variant that first appeared in Peru is a A series of mutations It is suspected that this may bring potential advantages to the virus, such as greater infectivity or possible higher resistance to neutralizing antibodies.Specifically, this variant is characterized by a unique set of mutations in the S gene encoding Spike (a protein used by viruses to bind and penetrate cells), including G75V, T76I, del247/253, L452Q, F490S, D614G e T859N; However, there is currently limited scientific evidence on the impact of these changes on virus characteristics. “The phenotypic effects of these genomic variants need to be further studied to better understand the impact on countermeasures and control the spread. -Added World Health Organization -. Further research is needed to verify the sustained effectiveness of the vaccine“.
