- The "undead" BA.3.2 variant lives on - new sequence from South Africa, EPI_ISL_20075682: 11-year-old girl, sample taken June 12, 2025, under pneumonia surveillance. #COVID19 #VariantWatch #BA32
- Concerning⚠️Mutated H3N2 influenza heads to northern hemisphere, prepare for worst seasonal flu epidemic in decades. ✴️7 mutations appeared in a strain of H3N2 seasonal flu in June 2025. These partially evade prior immunity, and are not fully covered by the current flu jab. ✴️Linked to
- Continued surveillance and variant analysis is important, as highlighted by the emergence and spread of BA.3.2. Lack of data sharing by GISAID is bad news.On Oct 1, 2025, @GISAID informed us that they had ended updates to the flat file of SARS-CoV-2 genomic sequences and associated metadata that we had used to update Nextstrain analyses since Feb 2020. GISAID's stated rationale was that their "resources are limited". 1/5
- Yesterday I was wondering why no new BA.3.2 sequences were showing up. Well, here’s a fresh one: EPI_ISL_20094964 from Western Australia. The variant is making its rounds globally — just as we feared. #BA32 #SARSCoV2 #VariantTracking
- A new BA.3.2 sequence. This time from the Netherlands, collected October 25. BA.3.2.1, EPI_ISL_20237246 🎃🎃🎃
- BA.3.2 still showing strong activity in Australia - 5 new BA.3.2 sequences added to GISAID today, the newest collected October 3. One sequence labeled BA.3 appears to be BA.3.2. #BA32 #GISAID #VariantTracking
- Here we go - BA.3.2 on the rise in Perth, Australia
- BA.3.2, the great pumpkin, is touring Europe. 🎃🎃BA.3.2 has arrived in the UK. One BA.3.2.2, collected October 5, was uploaded from Scotland today. Same branch as recent BA.3.2.2 from Germany & Slovenia. It has a few errors (ins214:ASDT misread & ORF1a:E4388K artifact). Ignoring those, the 1 notable new mutation is N:N126K.
- The Great Pumpkin, BA.3.2, is back. Two new BA.3.2.2 sequences from Western Australia, collected on October 17: EPI_ISL_20236455 and EPI_ISL_20236456.
- Two new BA.3.2.2 sequences from Sydney. EPI_ISL_20226642 and EPI_ISL_20226646 @LongDesertTrain, your call.
- 4% of new sequences reported from Germany today are BA.3.2.2 (n = 4), while 40% of the sequences from Western Australia belong to the same sublineage. An unexpected comeback in Germany - and BA.3.2.2 might be on the road to dominance in Western Australia (WA).
- Here we go - BA.3.2 on the rise in Perth, AustraliaReplying to @BigBadDenisBA.3.2.* variant making a solid debut in this week's wastewater for Perth - looks to be at around 15%. Quite impressive for a debutant.
- And a new BA.3.2.2 sequence from Slovenia (EPI_ISL_20236520, collected on November 2) - a first for the country. The Great Pumpkin remains active in different parts of the world...🎃
