Mathematical modelling indicates that #XBB15 could become dominant in the EU/EEA after 1-2 months, given the current low proportions reported in the EU/EEA & its estimated growth rate.
No signals of increased severity of XBB.1.5 compared to circulating omicron sub-lineages.

#XBB15 is a sub-lineage of #XBB, which evolved from two earlier lineages of #Omicron, with an additional mutation.
First detected in the US in October, has been growing in proportion in many countries around the world.

The proportion of XBB.1.5 in EU/EEA was lower than 2.5% for the final 2 weeks of '22 (the most recent period where variant proportions at this low level can be accurately estimated).
In the US, #XBB15 is currently spreading 12% faster than other variants.
