BA.3.2 might mark a step towards endemic coronaviruses rather than the next dominant variant.

First evidence in Europe of highly pathogenic avian influenza virus H5N1 infection in a dairy cow. Antibodies against H5N1 detected in a cow with mastitis and respiratory signs on a Dutch dairy farm at the end of December. A cat on that farm had died from H5N1. www.tweedekamer.nl/downloads/do...

Also seeing a decrease in BA.3.2* frequency in Denmark 🇩🇰 for the week Jan 5–11. Whether this represents a true trend reversal remains to be seen. For the following week, BA.3.2* frequency is currently ~50%, but based on only 4 samples.

Surprising: Marked drop in BA.3.2* frequency in Western Australia, for the second time in a row. Sample numbers are extremely low, so conclusions are shaky — but this may indicate a trend reversal.

So far there has only been one US patient reported with BA.3.2. Meanwhile, these are the wastewater detections to date. Want to know what's really going on? Check the wastewater; we don't miss shit.

25 new sequences from Ireland 🇮🇪, ~75% are BA.3.2 Almost 60% Jan 5-11 but very low sample numbers

14 sequences from Western Australia; 1 BA.3.2*. No BA.3.2* detected from Jan 5-11, despite ~50% frequencies in December. Unexpected - yes. Meaningful - likey not at this point, given the very low overall sample numbers.

60 new sequences from Germany 🇩🇪, 40% are BA3.2*. Update for December 1-21, 2025:

60 new sequences from Germany 🇩🇪, 40% are BA3.2*. Update for December 1-21, 2025:

48 new sequences from Scotland, roughly 30% are BA.3.2.

BA.3.2* has been detected in Northern Ireland. Roughly 35% of new sequences submitted to GISAID are BA.3.2*.

24 new sequences from England, roughly 30% are BA.3.2*

Roughly 10% of new sequences from Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿(n = 50) are BA.3.2*

94 new sequences from Luxembourg 🇱🇺, 6 are BA.3.2*

15 new sequences from Ireland 🇮🇪 submitted over the weekend, 6 are BA.3.2*

BA.3.2 has been detected in South Korea 🇰🇷. EPI_ISL_20333204, RE.1.1

BA.3.2* detected in Norway 🇳🇴. 10% of new sequences.

It's a slow but persistent wave. 22 more wastewater detections of BA.3.2 (including ALL recent samples form RI). It's staring to be the dominant lineage in many cases. I think the score on wastewater vs patient surveillance is now 44-to-1

Still more new NSP1 mutations in the BA.3.2 uploaded from the Netherlands today. We've never seen anything like this kind of rapid evolution in NSP1 (whose primary role is to shut down host-protein translation and degrade host mRNA). I've labeled all BA.3.2-specific NSP1 muts here. 1/3

Another RE.1.1 from New Zealand 🇳🇿. EPI_ISL_20326389. One BA.3.2* out of 42 submitted sequences.

3 out of 41 new sequences from England are BA.3.2*. 2 x RE.1.1 and 1 x RE.2.2

BA.3.2* detected in Belgium 🇧🇪; sample collected in December 2025 (EPI_ISL_20325437).

53 new sequences from Scotland; 15 are BA.3.2*. Notable increase in BA.3.2* frequency in Scotland in December, but partially based on low sample numbers.

New B.3.2 from Canada 🇨🇦: RE.2.2, collected Dec 29, EPI_ISL_20321661

Marked increase in the frequency of BA.3.2* infections in Denmark in December 2025.

BA.3.2 has arrived in Spain 🇪🇸. EPI_ISL_20316795, RE.2.2, collected in January 2026 in the course of non-sentinel-surveillance.

New BA.3.2* sequences from Germany 🇩🇪. Numbers are low, but the trend suggests that BA.3.2* spread in Germany may be slowing down.

BA.3.2 has arrived in Italy 🇮🇹 - two RE.2.1 sequences were submitted today.

5 new BA.3.2* sequences from South Africa 🇿🇦. All RE.1, 8% of total submissions.

3 new BA.3.2* sequences from New Zealand 🇳🇿. All RE.1.1, collected late December 2025, corresponding to 4% of total new submissions from NZ.

BA.3.2* arrived in Wales. RD.1.1, EPI_ISL_20308877. First spotted by @josetteschoenma.bsky.social .

1/3 New South Africa batch (small n): 6/36 BA.3.2* (5 RE.2, 1 RE.1)

69 sequences from Scotland; 6 are BA.3.2* Steady rise in Scotland: BA.3.2* relative frequency from 0.1% (Oct) to 2.9% (Nov) and 10% (Dec).

And look I'm sorry - but saying that maintaining COVID dashboards is focusing on unimportant things - is nothing less than purposefully missing the point. Any scientist worth their salt knows we don't just stop monitoring viruses because they stop being pandemic.

Seven more detections of BA.3.2 from US wastewater. It's fanning out, this week it includes detections in CA, UT, and NYC.

30 sequences from France and 80 from Spain - no BA.3.2. Counterintuitive given the strong BA.3.2 spread in 🇩🇪🇳🇱. Spanish samples are from autumn and may not reflect current circulation. But most French samples are from December. Not sure what’s going on.

BA.3.2 Era new deisgnations: we have a new branch of Ba.3.2.2 named RE.3 emerged in Mozambique and then spread to Europe (RE.3.1), We have also a new RE.2 branch named RE.2.3 defined by ORF1a:T2648N & ORF1a:T4065I RD.1.1.1 is a BA.3.2.1 with N:T271I RE.1.1.1 was discussed by @ryanhisner.bsky.social

BA.3.2 arrived in Canada. Two sequences out of 729 from December 2025 are RE.2.2 (BA.3.2.2.2.2). EPI_ISL_20300765 and EPI_ISL_20300794 - both from Ontario.

The first SARS-CoV-2 sequence uploaded in 2026 is.... ...a BA.3.2.2 from New York sampled from a traveler from Japan. This is the first BA.3.2 sample w/any connection to Japan. There have been no non-travel BA.3.2 collected in the US (yet). From the Western Australia S:P1162L branch. 1/9
