BA.3.2 is almost gone from Germany 🇩🇪. If I had bet money on BA.3.2 evolution, there would be no breakfast tomorrow. #BA32

BA.3.2* cannot gain ground in New Zealand 🇳🇿. #BA32

Numbers are still low, but the trend is clear - BA.3.2* is dominating in Spain 🇪🇸 #BA32

Low Numbers but BA.3.2 appears to be dominant in South Korea, it is important because it is the first NB.1.8.1 dominated country to switch to BA.3.2 @snpoehlm.bsky.social @josetteschoenma.bsky.social

BA.3.2 was first detected in South Africa 🇿🇦 in November 2024. Never reached dominance, never disappeard. 14 months after its emergence it accounts for 20% of all sequences. Unusual. #BA32

BA.3.2 dominates in Spain 🇪🇸. #BA32

New sequences confirm BA.3.2* dominance in France. #BA32

BA.3.2 is dominant in Luxembourg 🇱🇺. #BA32

BA.3.2 dominant in Queensland, Australia 🇦🇺. #BA32

BA.3.2 frequency in Sweden remains low. #BA32

Quite a comeback of BA.3.2* in New South Wales, Australia 🇦🇺. Dominance can be expected. #BA32

BA.3.2 may well be on the road to dominance in France 🇫🇷. The rise in BA.3.2 frequency is accompanied by a decline in XFG* frequency, as expected. #BA32

New sequences from Italy 🇮🇹. Confirm high frequency of BA.3.2. Attempt at dominance might have already ended. #BA32

BA.3.2 persists in Germany 🇩🇪 at low levels. At the same time, the frequency of NB.1.8.1 is increasing, paralleled by a decline in XFG frequency. #BA32

71 new sequences from Greece 🇬🇷, mostly collected in 2026. Roughly 15% are BA.3.2* #BA32

Siguiendo BA.3.2 en Europa, África, Asia y América del Norte. Aún no hay señales desde América Central o del Sur. ¿Existen paneles públicos de aguas residuales o páginas de monitoreo de SARS-CoV-2 que cubran América Central o del Sur? Los enlaces serían de gran ayuda. #BA32

Following BA.3.2 in Europe, Africa, Asia and North America. No signals from Central or South America yet. Are there any public wastewater dashboards or monitoring pages covering Central or South America? Links would be very helpful. #BA32

Closely following BA.3.2 here. It is still unclear what trajectory it will take. If BA.3.2 fades out - are there any obvious candidates that could challenge NB.1.8.1 and XFG in the near term? #BA32

Recent increase in BA.3.2 frequency in Italy 🇮🇹. Cave: Very low number of sequences. #BA32

BA.3.2 frequency in Sweden remained constant. #BA32

BA.3.2* uptick in New Zealand 🇳🇿 not supported by latest sequences. #BA32

New sequences from Northern Ireland 🇬🇧: BA.3.2* is now dominant. ~65% of sequences are BA.3.2*, with a corresponding decline of the previously dominant XFG lineage. So far, this increase does not appear to be associated with a COVID-19 wave across age groups. #BA32

Update: Now 16 SARS-CoV-2 sequences from Italy collected in February 2026. 5 (~30%) are BA.3.2* #BA32

16 new BA.3.2* sequences from Ireland 🇮🇪 were submitted today, and 100% are BA.3.2*. Only "2026" is provided as collection date. Not sure why. Interesting, however: All samples are from donors of the 0-18 age group. #BA32

Downward trend of BA.3.2 frequency in Germany 🇩🇪 continues. #BA32

Only 6 sequences collected in Italy 🇮🇹 in February 2026 submitted so far - but 3 are BA.3.2* (all from wastewater surveillance)👀 #BA32

Uptick in BA.3.2 frequency in Sweden 🇸🇪 in February. Caveat = low n. #BA32

Increase in BA.3.2 frequency in Spain 🇪🇸 but low sequence numbers prevent solid conclusions. #BA32

The BA.3.2 frequency in Slovenia 🇸🇮 may be following a pattern seen in other countries - a marked increase followed by an abrupt drop. However, the data mainly highlight that reduced sequencing activity limits the ability to draw solid conclusions about variant spread.

BA.3.2 frequency in New South Wales, Australia 🇦🇺: ➡️Marked increase in December 2025. ➡️Marked drop at the beginning of January, followed by stable frequency in January/February 2026. ➡️The drop largely coincides with the summer holidays (22 Dec 2025 – 26 Jan / 2 Feb 2026).

The uptick of BA.3.2 in New Zealand 🇳🇿 has now been confirmed by newly uploaded sequences. Whether this trend will continue remains unclear - at present, BA.3.2 accounts for only 4% of sequences available for KW 09.

Correction: Newly released sequences from Northern Ireland 🇬🇧 indicate that the frequency of BA.3.2* remains high. This is noteworthy in light of recent posts by @gwladwr on X showing that BA.3.2* frequently targets children and that there is an uptick in COVID-19 cases among children. #BA32
