It is estimated that Ómicron’s BA.2 lineage represents more than 24% of new cases in Portugal | coronavirus
It is estimated that the BA.2 lineage represents 24.3% of new cases of SARS-CoV-2 infection Monday in Portugal, refers in the latest report on the situation of the genetics of the SARS-CoV-2 coronavirus in the country, released this Tuesday by the National Institute of Health Doutor Ricardo Jorge (Insa).
BA.2 a known lineage of the Ómicron variant comes from a genetic variety in Portugal, as it has a numerous variety of countries. In Portugal, coming from December 27th for the first time in the samples, the genomic sequencing between January 202 and January 2, 22. Since then, it has been gradually.
If we consider the latest data from the omic sequencing samples (which always have a delay of a few days), BA.2 represented about 8.6% of the samples still in the week between January 31st and February 6th (and these data genomics are being analyzed). But, for its most current value, indirect monitoring was done through the proportion of non-SGTF positive samples.
What you mean? The Ómicron variant designed in Portugal and is dominant (BA.1) has followed through monitoring in a real-time detection failure of another laboratory gene from the origin of some laboratories. This Monday, BA.1 represents 75.7% of new cases of infection. “The revised and updated indicators to the data in the report show a trend of increasing ‘failure in the proportion of probability data’ with 7; probable case indicator BA.1; probable case indicator BA.1), with an estimated frequency of 7.7% on February 14th”, reads the note on the report.
So the remaining 24% could be from the fifth BA.2 (which doesn’t have the S gene flaw) or the week variation, but Delta’s circulation is already very low (less than 1% of the year) ). Thus, samples that do not belong to BA.1 will be shown from BA.2. Thus, it is estimated that BA.2 “represents 24.3% of positive samples on February 14, 2022”, refers in the note.
This is the most recent portrait of the genetic diversity of SARS-CoV-2 in Portugal. Since the beginning of June 2021, Insa has been analyzing, on average, 524 SARS-CoV-2 sequences per week. These samples come from districts spread over 18 regions of mainland Portugal and the autonomous regions of Madeira, covering an average of 133 municipalities. To date, there have been 26,649 SARS-CoV-2 genome sequences.
