Here's an animated map showing the spread of the BA.3.2.* variant, nicknamed "Cicada".

The other main hotspots have been South Africa, Western Australia (since July) and Germany (from mid-October).

Locations are approximate - typically country and state/province.

Here's the latest variant picture with a global scope, to mid-November.

BA.3.2.* has continued to show signs of growth. Recent samples have been reported from South Africa, Australia, across Europe, and a traveller entering the US from Kenya.

🧵

Here are the sub-lineages of BA.3.2.*. The new RE.1.1 and RE.2.2 sub-lineages are driving the recent growth, rising to 2.1% frequency.

The Variant Hunters expect that these will likely be superseded by further child lineages with added mutations, to boost transmission.
🧵

Here are the leading countries reporting BA.3.2.*.

Further samples were shared from Australia (13%), Germany (10%), Ireland (7%) and the UK (1%). Multiple chains of local transmission are underway.
🧵

Globally, BA.3.2.* showed a slightly slowing growth advantage of 3.5% per day (25% per week) over XFG.* "Stratus". Any crossover looks a couple of months away at that pace.
🧵

New child lineage XFG.1.1.1 is emerging as another contender. The parent XFG.1.1 was characterised by a reversion to Spike W452R, which captured the attention of the Variant Hunters.

XFG.1.1.1 has grown to 2% in the US, and reached 5% in France.
🧵

Globally, XFG.1.1.1 is showing a very strong growth advantage of 3.5% per day (25% per week) over other XFG.* "Stratus". Any crossover looks a couple of months away at that pace.
🧵

As usual, I will go into more depth for the countries and regions that have shared enough recent data for a coherent analysis, on separate threads over the next day or so.
