This is quite late but our lab has a preprint out about a SARS-CoV-2 situation we had in mink in Lithuania back in 2021. It's a doozy with re-emergence of extinct lineages, a country-wide test of all mink farms in Lithuania & some interesting dynamics in mink. www.medrxiv.org/content/10.1... 1/5🧡

Metatranscriptomic detection of rabbit hemorrhagic disease virus 2 in karoro (southern black-backed gulls) | Journal of Virology Rabbit hemorrhagic disease virus 2 (RHDV2; species Lagovirus europaeus) is a highly pathogenic lagovirus (Caliciviridae) responsible for a lethal disease in rabbits and hares (1). First identified in ...

We found RHDV2 in gulls! While the virus is likely to be dietary in origin, this suggests that birds may act as mechanical vectors for virus spread. Work by Steph Waller, @dwinter.bsky.social @eddieholmes.bsky.social @mongoosekiwi.bsky.social et al. journals.asm.org/doi/10.1128/...

Rhys and I found some weird influenza B viruses in fish a few years ago. For 2, the HA's bind a2,3 sialic acid ("bird type receptor"). The Siamese algae eater virus NA has a highly conserved structure and active site. No cross-reactive antibodies in human sera.

The next pandemic is coming. NZ isn't ready Special report: The island nation is less prepared for a pandemic than it was five years ago, even as new threats emerge overseas.

I spent about 30 hours over four weeks reading all 716 pages of the report of the Royal Commission into the Covid-19 response, then wrote two articles detailing its findings and recommendations.

With the paywall now lifted on both of those pieces, here's what I found. 🧡

Bird Flu Is a National Embarrassment America should have more aggressively intervened almost a year ago.

Essential reading from @katherinejwu.com @theatlantic.com.

For months, we've passively watched H5N1 tear through animals. A year into the cattle outbreak & it remains out of control. H5N1 is everywhere.

If H5N1 causes a pandemic, it will be because we let it.
