Abstract
Genetic and structural analyses here presented do not provide evidence for a particularly high risk of XBB.1.5 expansion to become a new, global public health threat. The Omicron variant of concern, and more specifically BA.5 and its descendant lineages, remain the dominant variants circulating globally [4]. The variant XBB.1.5 appears to spread even more slowly than the last sub-variants that have caused concerns in 2022. However, it cannot be excluded that new mutations will occur and make XBB.1.5 more dangerous. In this context, extensive genome-based monitoring must continue uninterruptedly because it is the only way to identify and/or predict important changes in the genomic composition of SARS-CoV-2.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
