An immunocompromised man, who was chronically infected with BA.1.17 for more then 1,5 years, until unfortunately he died because of his underlying disease, was tested repeatly. 50 nucleotides mutated

Big thanks to this patiënt and to Magda Vergouwe, Marcel Jonges , Matthijs Welkers et al.

📄 📄 Our molnupiravir work is now out after peer-review! We definitively demonstrate that molnupiravir has resulted in viable SARS-CoV-2 viruses with significant numbers of mutations, in some cases with onwards transmission of mutated viruses. nature.com/articles/s4158…

Recently we identified a human swine flu case A(H1N1)v in a respiratory surveillance study among the general population in The Netherlands. No severe disease, and no evidence for any forward transmission.

How important is ORF9b? More important, I think, than almost anyone has realized. ORF9b is often neglected—it is ignored on phylogenetic trees & on GISAID sequences. I see 9 lines of evidence indicating it's a major player. But they require some background. /1

Between May-September 2022, 135 MSM were positive for in Amsterdam. We found that anal and lesional samples🧫 had a higher viral load than throat samples. 👉Showing that in this outbreak, sexual contact was the main transmission route.

Among the 401 samples were

🔸2 positive cases , sampled prior to the first known confirmed case in the 🇳🇱
🔸399 negative samples, dating as far back as February 2022

= suggesting that mpox transmission did not occur before May 2022

1/ Every person who rapidly shares viral genome sequence data should be celebrated & I'm proud to have helped GISAID Initiative grow. I believe in the platform & its cause is noble. Most of all, I believe in the global community that is the true fabric of GISAID. But there's a problem.. 🧵

Following the death of an 11-year-old girl from highly pathogenic avian in Prey Veng province, , Ministry of Health reports 12 more infected people, 4 of whom have begun to show symptoms. Results of diagnosis expected tomorrow.

Very cool to see nature cover our preprint! I agree with Sarah Otto. “Given the large-scale risks of this mutagen producing new variants faster, including variants that are immune evasive, I encourage public-health leaders to call for a global halt to [molnupiravir's] use.” 1/

De groeiende varianten gingen samen in week 4 in Nederland richting de 50%. Het is nu week 6

Amsterdam UMC , inBiome, UMCG en het Erasmus MC hadden gelukkig hun samples voor week 4 snel op GISAID Initiative staan. 🙏

Ondanks het afnemende aantal samples, samen toch nog boven de 100

💥 New preprint out today

We conclusively demonstrate that mutational events caused by molnupiravir treatment can be seen in globally sequenced SARS-CoV-2 genomes, in some cases with onwards transmission.
