A fresh wave of hospital admissions has clearly started in Denmark, and also in Belgium, France and the Netherlands, with remarkable synchronicity. The more intense genomic sequencing data from Denmark is likely a useful guide to the lineages driving the waves in other countries.

Weekly hospital admissions are up to 63/M in Denmark, following a trough around 21 November at 41/M.

As with the recent BQ.* waves, it's remarkable how a relatively low frequency of a new lineage can spark severe outcomes.
