![]() The 465 mutation is present in about 35% of coronavirus sequences reported worldwide, including another that’s rising in prevalence in the Northeast, FL.1.5.1, suggesting that it is conveying some kind of evolutionary advantage over previous versions.ĮG.5 also now has its own offshoot, EG.5.1, that adds a second mutation to the spike. This mutation has appeared in other coronavirus variants before. Scientists aren’t sure exactly what new tricks it enables the virus to do, but variant hunters are paying attention because many of the new XBB descendants have adopted it. Your recent cold could be Covid-19, as the nation goes into a late summer waveĮG may sound like a whole new flavor of the virus, but it’s not it’s a spinoff of the XBB recombinant strain of the Omicron family. And it represents another incremental tweak to the virus rather than a major evolutionary leap like the original Omicron strain.Ĭompared with its parent XBB.1.9.2, it has one extra mutation to its spike, at position 465.
