Covid-19 variant 2023: US, UK, 2 other countries detect highly mutated Coronavirus variant. Details here
Dubbed BA.2.86 and informally referred to as Pirola among variant trackers on social platforms, this emerging variant exhibits over 30 changes in amino acids within its spike protein when contrasted with its closest predecessor, the BA.2 subvariant of Omicron. Dr. Jesse Bloom, a researcher specializing in viral evolution at Seattle's Fred Hutchinson Cancer Center, provided this insight, as per a CNN report.
As of now, a mere six cases of the BA.2.86 variant have been officially detected across four nations including the US. However, the apprehension stems from the possibility that these reported cases could be indicative of a more extensive presence, given the reduced global scrutiny of variants. The detection of this variant started in Israel, subsequently extending to Denmark with three recorded sequences.
Additionally, the United States and the United Kingdom each identified two instances. On Thursday, the World Health Organization classified BA.2.86 as a «variant under monitoring,» urging nations to track and report any identified sequences. Variants under monitoring that exhibit characteristics like heightened disease severity or evasion of established vaccines and treatments can be promoted to the WHO's list of variants of interest or concern.
The designations XBB.1.5, XBB.1.16, and EG.5 are currently considered variants of interest, whereas no variants of concern have been designated. Earlier this year, the White House conducted a discreet survey among around a dozen Covid-19 experts specializing in virus evolution. This survey aimed to gauge the likelihood of a significantly mutated variant emerging within the next two years.
