*** Ontario Variant Update (to: Aug. 16, 2025) *** Ontario COVID sequence updates have been more frequent over the past month with the XFG.* "Stratus" family of variants now at 74% of sequences, NB.1.8.1.* "Nimbus" at 22% and LP.8.1.* down to 3%. #Variants #COVID #XFG #Stratus 🧪🧵1/
Line graph showing COVID-19 variant frequencies in Ontario, Canada, from May to mid August 2025, based on 1,772 sequenced genomes. The XFG.* Stratus variant rises sharply to dominate over 70% by August. Other variants, including FLiRT and LP.8.1.*, decline over the same period, while NB.1.8.1.* Nimbus remains steady around 20% and several minor variants remain at low levels.

Variant update for Ontario, Canada (October 15, 2023) More than 60% of sequences are from the EG.5.* [Eris] family with the others at or below 10% but there is still quite a mixture of variants circulating with different immune evasion capabilities. 🧪🧵1/ #COVID #Variants #COVID-19

Variants: JN.1 vs KP.2 vs KP.3.1.1 What do the variant designations like KP.3.1.1 mean and how does it compare to JN.1? How important is just 1 mutation? Can 1 mutation potentially affect our immunity and how vaccines are designed? Read on to find out more. 🧪🧵1/ #Variants #COVID #Immunity
Structural alignment of the AF2-predicted RBD conformational ensembles in the complexes with ACE2 for JN.1 (A), KP.2 (B) and KP.3 variants (C). Structural alignment of the AF2-predicted conformations with high pLDDT values > 80.0 and the cryo-EM structure of the BA.2.86 RBD-ACE2 complex (pdb id 8QSQ). The RBD conformations are shown in ribbons. The sites of unique BA.2.86 mutations D339H, K356T, R403K, V445H, G446S, N450D, L452W, N460K, N481K, A484K, F486P, R493Q are shown in blue spheres on panels (A-C). Mutation L455S in JN.1 is shown in red spheres on panel A. The positions of KP.2 mutations R346T, L455S and F456L are shown in red spheres on panel B. The positions of KP.3 mutations L455S, F456L and Q493E are shown in red spheres on panel C. Image from: https://www.biorxiv.org/content/10.1101/2024.07.09.602810v1.full
