Interesting SarsCoV2 variant report update by @CorneliusRoemer ( May 21st ,2025) 🔥Your attention for XFG and NB.1.8.1, a double variant worldwide NH summer/SH winter surge? 1. Global overview: Based on sequences collected in 2025 and shared until 2025-05-18, - XEC continues declining and is no longer dominant in almost all countries, except for Japan where it is still dominant and growing. - LP.8.1 is dominant in North America, parts of South America (Brazil), much of Europe and South Africa (the only continental African country with more than 10 sequences from 2025). It is still growing in Australia. - LF.7 appears to have peaked. In Russia and Peru it was was dominant in Q1 2025 and at around 40% in Singapore and Chile. - NB.1.8.1 is growing globally. It is dominant in Hong Kong and China and at 5-30% in most other countries with sequences collected end of April 2025. - XFG (described below) is most common in North America and Europe where it is growing around as fast as NB.1.8.1 and at similar frequencies. 2. Comparison of XFG and NB.1.8.1 with interesting global insights!👇 github.com/neherlab/SARS-…
