CDC and WHO Monitor Highly Mutated COVID Variant BA.2.86 in the US

The U.S. Centers for Disease Control and Prevention (CDC) is monitoring a new lineage of the virus that causes COVID-19, named BA.2.86, which has been detected in the United States, Denmark, and Israel. The World Health Organization (WHO) has classified BA.2.86 as a "variant under monitoring" due to its numerous mutations. While it is uncertain if BA.2.86 will out-compete other strains or evade immune responses, early analysis suggests it may have equal or greater ability to escape antibodies compared to the XBB.1.5 variant targeted by upcoming booster shots. Further sequencing data is needed to determine its transmissibility. The CDC advises following existing COVID-19 protection measures, and experts express concern that BA.2.86 could potentially cause a significant increase in cases.
