Until Friday, Australia was the only continent free from HPAI H5N1. Sadly, this is not the case - a 2344b confirmation in a Brown Skua, and a suspected case in a Northern Giant Petrel which turned up in WA. 👉 www.abc.net.au/news/2026-06... (1/x)

These 2 new #H5N1 #birdflu infected herds in Texas & Utah have made it to #USDA 's official count. total now 1,109 herds in 19 states. www.aphis.usda.gov/livestock-po...

There’s a LOT going on as researchers and public health experts race to respond to the Ebola Bundibugyo outbreak in DRC and Uganda before it grows bigger. Some really important questions still open, but also a few answers coming into view🧪 My overview in @science.org is here (and thread coming):

Initial genomic characterization of the Bundibugyo virus outbreak in Eastern DRC with cases in Uganda. Join work between INRB in DRC and CPHL in Uganda plus many partners. virological.org/t/initial-ge...

With the news that a French woman and someone from the US, both of whom had been on board the MV Hondius, have tested positive for #hantavirus, the Andes virus outbreak is now up to 10 cases: That's eight confirmed and two probable. Given the long incubation period, there may still be more cases.

🚨New paper!🚨 Our study showing that H5N1 influenza viruses can remain infectious in unpasteurised milk for, basically, as long as you are likely to encounter that milk has now been published: www.microbiologyresearch.org/content/jour...

We are incredibly excited to see our most recent story out @nature.com today:HIV triggers CD4-signaling to remodel nuclear pores and license infection!A heroic effort led by our very own @d-mesner.bsky.social & @mattvxwhelan.bsky.social! @blizardinstitute.bsky.social Link: tinyurl.com/HIVNup 1/11

Still time to apply for one of three joint virology PhDs @cvrinfo.bsky.social and @pirbrightinst.bsky.social, including one with myself and the fantastic @peacockflu.bsky.social! Informal enquiries welcome by e-mail (including re the primary location of ours, which is negotiable), deadline 8th May

Excited to advertise a fully funded PhD with @socialinfluenza.bsky.social investigating how influenza virus evolution differs between different avian hosts (and how this impacts pandemic potential). Joint between @pirbrightinst.bsky.social + @cvrinfo.bsky.social www.findaphd.com/phds/project...

As foot-and-mouth disease explodes in South Africa, experts warn of threats in other countries www.science.org/content/arti...

Took a long time to get this done, 2-3 years on Figure 1 alone but glad it's finally out!! www.nature.com/articles/s41...

We did a thing: Scientists find a new way coronaviruses can get into human cells www.cam.ac.uk/research/new...

🚨New pre-print!🚨 Using a panel of different H5N1 clade 2.3.4.4b viruses and human seasonal influenza, and mammary explants from common beef and dairy cattle breeds, we add to the growing data showing that H5N1 spillovers into cattle should be seen as an ongoing risk www.biorxiv.org/content/10.6...

🚨New pre-print!🚨 Because influenza virions are highly variable in form no single method can show their molecular architecture in detail. Here, we integrate multiple structural and compositional approaches to identify new features of these beautiful virus particles www.biorxiv.org/content/10.6...

Excited to advertise a fully funded PhD with @socialinfluenza.bsky.social investigating how influenza virus evolution differs between different avian hosts (and how this impacts pandemic potential). Joint between @pirbrightinst.bsky.social + @cvrinfo.bsky.social www.findaphd.com/phds/project...

Our paper describing the #cryoEM structures of unusual spike proteins from marine mammal–infecting gammacoronaviruses is now published in PLOS Pathogens! 🐬 journals.plos.org/plospathogen...

Really excited to be able to share our latest preprint, describing how during its evolution in cattle, H5N1 has got better at using a type of alternative receptor that's abundant in cows, but not found in humans and birds. www.biorxiv.org/content/10.6...

Are you excited by virology? Would you like to do a PhD? Three fantastic opportunities are available to do joint PhDs between @cvrinfo.bsky.social and @pirbrightinst.bsky.social Details in the thread below - please share! Deadline 8th May 2026, fully funded for UK Home students (1/4)

Do you like microscopy? Do you think viruses are cool? Do you want to advance our understanding of one of the world's most important pathogens? Come and do your PhD with myself and the fantastic @peacockflu.bsky.social, at @pirbrightinst.bsky.social and @cvrinfo.bsky.social 🤓🦠🐓

5 more dairy cows tested positive for #H5N1 #birdflu antibodies on the Dutch farm where a previous cow tested positive. No surprise that if 1 was positive, others would be too. This dairy farm is the first outside the US to report H5N1 transmission. www-melkvee-nl.translate.goog/artikel/1450...

🚨New Pre-Print🚨 Although H3N2 subclade K has multiple mutations in HA, neutralisation assays with pre-epidemic human sera show only moderate antigenic drift, and vaccines used in the 2024/2025 flu season induced cross-neutralising immunity www.medrxiv.org/content/10.6...

First evidence in Europe of highly pathogenic avian influenza virus H5N1 infection in a dairy cow. Antibodies against H5N1 detected in a cow with mastitis and respiratory signs on a Dutch dairy farm at the end of December. A cat on that farm had died from H5N1. www.tweedekamer.nl/downloads/do...

Interested in high containment work on viruses? We have an opening at the Pirbright Institute, working on high consequence viruses of livestock and humans in the core CL3 team. isw.changeworknow.co.uk/pirbright/vm...

Really excited our paper about how H5N1 rapidly adapted to cattle (and how these adaptations also increased its ability to infect cells from the human respiratory tract) is now published! www.nature.com/articles/s41...

We find that subclade K viruses are antigenically advanced; however, this year's flu vaccine surprisingly elicited antibodies in many individuals that efficiently recognized these viruses. The implications are clear: go get this year’s vaccine if you haven’t already! www.medrxiv.org/content/10.6...

#H5N1 : An infected herd was recently detected in Wisconsin, and genome sequencing indicates that this is yet another spillover event, making it the fourth detected one. How do these spillovers happen and why are they restricted, so far, to the US? www.aphis.usda.gov/news/agency-...

Our lab's paper describing the North American H5N1 epizootic is out now in Nature! So thrilled to have this out, and congratulations to @lambod50.bsky.social for all the fantastic work on this: www.nature.com/articles/s41...

I want to spell this out in case the implications aren't clear: This means all public tools/webapps of GISAID data (all the ones you've been used to seeing thru the pandemic, as far as we can tell) are prohibited. The file allowed this. Cut that - cut off all tools the public & others were using.

🚨 NEW: The majority holder of the world's genetic sequence data is a bad actor who can cut off access to critics and competing services. We've tolerated this for years, and now it threatens the pandemic treaty. Time for WHO to step in. With @ctrlalttim.com: www.thinkglobalhealth.org/article/to-f...

After years in the making, Joe McKellar @viroscope.bsky.social’s final PhD paper is finally out today in PNAS! 🎉 🎉🎉 www.pnas.org/doi/10.1073/...

And the sister paper from collaborator and good friend Katie Doores ... A deeper dive into how some of these broadly neutralising #sarbecovirus #coronavirus #sars2 #covid antibodies actually work www.biorxiv.org/content/10.1...

Our first post on here and it's a doozy 😍🤩. Our epic piece on #sarbecovirus host range. #virology #sars2 #covid #vaccines. Enjoy and please repost. www.biorxiv.org/content/10.1...

Really excited to have been a small part of this work investigating sarbecovirus host range, receptor usage and antigenicity! www.biorxiv.org/content/10.1101/2025.09.03.673949v1

In new study led by @ckikawa.bsky.social, we provide near real-time data on human neutralizing antibody landscape to influenza by measuring ~26,000 titers to >100 recent viral strains Data can inform vaccine selection & evolutionary/epidemiological modeling www.biorxiv.org/content/10.1...

New preprint! If some merbecoviruses use DPP4 and others use ACE2, what do those hedgehog merbecoviruses use?! As it turns out, neither! In our latest study, we uncover the "missing" receptor for the MERS-related viruses in hedgehogs. [These findings were first shared at ASV this year] (1/6)

The cow udder may be a mixing vessel where different strains of influenza can recombine--"underscoring its potential role in generating novel influenza viruses with pandemic risk." [Preprint] www.biorxiv.org/content/10.1...

Finally!

Really excited to have been a part of this study, lead by @willharv.bsky.social on how reassortment of H5N1 in birds has lead to a 'specialist' genotype that thrives in seabirds and drives summer/spring (rather than winter) waves of poultry outbreaks www.biorxiv.org/content/10.1...

Come work with us👇

Very pleased to have our new work out where we perform a structure/function study on the bornavirus polymerase complex with fantastic coauthors. Have a read www.nature.com/articles/s41... @warwicklifesci.bsky.social @loiccarrique.bsky.social @franziskaguenl.bsky.social

🚨 New paper alert! 🚨 Here we show that stabilized influenza hemagglutinin HPAI H5 immunogens improve the quality of elicited antibody responses. Thank you to @open_phil for funding this work! bit.ly/4lgr0rM

Exciting new work from my @ciddpsu.bsky.social colleagues showing that pandemic H1N1 immunity reduces susceptibility to H5N1 infection and disease in ferrets.

🦇 NEW RESEARCH: Our 3-year study of Australian flying foxes identified six co-circulating coronaviruses, with highest rates of infection and co-infection in young bats, and evidence of circulating recombinants 🧪🌏 🧵 Available open access in @natcomms.nature.com 📄 www.nature.com/articles/s41...

Very happy that our paper on the receptor binding properties of contemporary H3N2 viruses is now published @CellReports # glycotime www.cell.com/cell-reports...
