The identification of a new subvariant of Sars-CoV-2, the virus that causes Covid, was confirmed this Wednesday (27) in the city of São Paulo. According to the Dasa laboratory network, the discovery comes from the sample of a three-year-old child. The material was collected on February 16, 2022 for an RT-PCR exam.
According to the laboratory, this recombination of the coronavirus had not yet been identified anywhere in the world and is not cataloged on Gisaid, a platform that consolidates genomic data on the virus from more than 70 countries.
Even if this discovery occurred, it does not, however, indicate that underlining is already categorized as a new subvariant. “For it to be recognized as a new recombinant strain, it is necessary that at least five samples from different individuals contain this recombinant,” the laboratory said in an official statement.
In addition to this sequencing, Dasa confirmed two other new cases of the omicron XE subvariant in Brazil, identified in two people who carried out tests in laboratories of the network.
The first case of this subvariant was recorded in Brazil on April 7. It is a hybrid of BA.1 and BA.2 strains. Prior to that, she was initially identified in January in the UK.
According to a survey recently carried out by ITPS (Instituto Todos Pela Saúde), the BA.2 subvariant of the ômicron is the majority among Covid cases in Brazil, representing almost 70% of the samples analyzed in diagnoses made between the 3rd and 9th of April.
