SHREVEPORT, La. – The most current genomic sequencing report from the Middle of Emerging Viral Threats (CEVT) at LSU Health Shreveport located that all COVID-19 optimistic samples sequenced have been the Omicron variant, with a person sample being the BA.2 sublineage.
Even though this is the first time that BA.2 has been detected in north Louisiana, it is not a new variant of the SARS-CoV-2 virus that will cause COVID-19. BA.2 is a subvariant of the Omicron lineage that is now dominant in the United States. There are three lineages of the Omicron variant – BA.1, BA.2, and BA.3 – as of February 2022. The prevalence of BA.2 in new instances of COVID-19 has greater in international locations like Denmark and South Africa but is even now lower in the United States.
Conclusions from preliminary research on the BA.2 Omicron subvariant show there are key variations from BA.1.
“Early reports from a Japanese lab that have not nevertheless gone through peer assessment point out BA.2 may perhaps trigger much more severe condition than the BA.1 sublineage. In these early research, the antigencity is also unique among the two lineages of Omicron, which means that it is doable BA.2 may perhaps interact in different ways with the host immune program. These are early details and must be interpreted with caution, but they provide potential important insight about BA.2,” explained Krista Queen, PhD, Director of Viral Genomics and Surveillance for the Center of Excellence for Emerging Viral Threats at LSUHS.
Complete study on virus variants is ongoing when experts and public health and fitness officials keep on to check the unfold of COVID-19 and detect variants that are circulating amid populations applying important details that genomic sequencing delivers.
“Mutations in viruses are not unusual and variants are anticipated to occur. The fantastic information is that we have the means in just the Middle of Rising Viral Threats to sequence SARS-CoV-2 genomes,” reported Queen. “Without this, our genomic surveillance attempts in north Louisiana would not be as profitable. Simply because of sequencing we can figure out what variants are…
