dc.description	From February 2023, XBB (and other recombinant) SARS-CoV-2 variants dominated circulating SARS-CoV-2 variants worldwide but have since been replaced by BA.2 sublineage variants. Since November 2023, the BA.2.86 sublineage JN.1 has rapidly increased globally and has replaced XBB.1.5-like lineages. A new variant with an unusually high number of mutations, BA.2.86, was detected in Israel first on August 13th 2023 and eventually spread globally though at relatively low prevalence. A sublineage of BA.2.86, JN.1, has since emerged rapidly and has become the predominant variant globally. It was made a Variant of Interest by the WHO on December 19th 2023 due to this rapid rise. The updated WHO risk evaluation published April 15th 2024 indicates that it possesses some antigenic advantage allowing it to evade previous immunity. However, while there are likely to be increases in case numbers, there is no indication of impact of vaccine effectiveness or increased disease severity as compared to other circulating variants.	en_US
