The new KP.2 lineage of SARS-CoV-2 is showing signs of spread. It was first detected in samples collected in early January from Assam, India. It has since showed up in New Zealand, across North America, Europe, Asia and Australia.

Here's an animated map showing the spread of the KP.2 lineage.

Locations are approximate - typically country and state/province.

Samples from India dried up during January, so it's unclear if KP.2 is still spreading there.

As the lineage designation has not yet flowed through to Nextclade, I'm approximating it by searching for samples with the characteristic mutations.

PS:
KP.2 adds the Spike R346T mutation to JN.1.11.1.

Globally, KP.2 is showing a very strong growth advantage of 14% per day (101% per week) over other BA.2.86.* "Pirola" (including JN.1.*) since February. That predicts a crossover in late March.
