However, the CDC emphasises that comprehensive laboratory testing of antibodies is challenging at this stage due to limited access to virus samples.

The CDC had previously announced its monitoring of the highly mutated BA.2.86 lineage, which has been detected in several countries, including the United States, Denmark, and Israel. The CDC has clarified that the recent rise in hospitalisations in the United States is not likely attributed to the BA.2.86 lineage.

As research and monitoring continue, health authorities worldwide will closely observe the behaviour and impact of this emerging variant.

WHO says ‘Variant Under Monitoring’ Recent increases in Covid-19 cases across the US, Europe, and Asia have been largely attributed to the EG.5 'Eris' subvariant, which is a descendant of the Omicron lineage that first emerged in November 2021.

This subvariant currently accounts for about 17 percent of new Covid-19 cases in the United States, slightly surpassing the 16 percent attributed to the next most common lineage, XBB.1.16, according to the latest estimates from the US CDC. The World Health Organization (WHO) has classified EG.5 as a "variant of interest," indicating a need for closer monitoring.
