💫 New paper out in @nathealth.nature.com 💫 Characterization and forecast of global influenza subtype dynamics www.nature.com/articles/s44... We analyzed the subtype compositions of countries' influenza waves globally to understand their drivers and test predictions of next season's composition.

The Ebola outbreak in the DRC has now crossed 10,000 cases and is getting close to 5,000 deaths. It is a staggeringly large outbreak and it continues to grow rapidly, with 96 new cases in the last 24 hours alone. #IDsky 🧪 insp.cd/sitrep-n164-...

And that's a wrap! We hope you enjoyed #CCS2026, and on behalf of the organizing committee, we wish you a safe and pleasant journey home. See you in Poland for #CCS2027 and in China for #CCS2028!

This summer, the @ecdc.europa.eu has so far counted 1715 locally acquired cases of West Nile virus infection, "the highest number of WNV infections in humans ever reported" in Europe. The disease also spread over a larger are than ever before. 🧪 wnv-monthly.ecdc.europa.eu #IDsky

Twenty years ago we published “Sharp transition towards shared vocabularies in multi-agent systems.” It feels unexpectedly current. New post on AI agents, conventions and what they might enable: baronca.substack.com/p/sharp-tran...

🎉 We’re happy to announce that Complexity72h is coming back to Northeastern University London! After the wonderful experience of last year, we’re excited to return to this beautiful venue for another edition! Save the dates! 📅 21–25 June 2027 ... and stay tuned for the Call for Projects opening!

139 genomes now sequenced from the ongoing 2026 Bundibugyo virus disease outbreak in DRC, spanning 16 Health Zones. Led by INRB with support from the ARTIC network (Wellcome Trust and Gates Foundation). Full analysis: virological.org/t/genomic-ep...

The first Ebola case has been reported today in France. Our rapid risk assessment last month showed that France consistently ranked among the European countries at highest risk of importation if an Ebola case were to arrive in Europe from the ongoing Bundibugyo outbreak.

"I am afraid this manuscript may contribute not so much towards the field's advancement as much as towards its eventual demise."

Looking forward to an exciting week in Paris!! 👇 🥐 🙃

Since we just came out of #netsci2026 it's a good opportunity to find about every network science starter packs out there. Thankfully starterpacks search engines are here to cut down that work. bsky.app/starter-pack... by @nwlandry.bsky.social

1. New #Ebola numbers from DRC's National Institute of Public Health: — 18 new confirmed cases on 6/3; that brings the confirmed case count to 381. Two more deaths puts the death toll among confirmed cases at 64. Seven people have been deemed cured (+1). — 55.5% of case contacts are being followed.

#NetSci2026 2nd keynote of the day Alessia Melegaro argues the importance of considering complex factors (demographics, social structure, and behaviors) for epidemics modeling @netscisociety.bsky.social @netsciconf.bsky.social

New #SocioPatterns study in PNAS: we studied how social behavior and psychological well-being evolve at Concordia Station in Antarctica during the extreme isolation and confinement of a 10-month overwinter mission. Lessons for deep-space crews. www.pnas.org/doi/10.1073/... #NetSci #NetworkScience

The amazing teams around Dav Ebengo & Placide Mbala-Kingebeni, alongside the Institut National de Santé Publique and AfricaCDC have led an effort to improve understanding of the current #Bundibugyo Ebola outbreak. Data: github.com/INRB-UMIE/Eb... Dashboard: inrb-umie.github.io/EBOV2026_Epi...

As discussions on Ebola and border controls intensify, it is important to go back to what available scientific evidence actually shows. In @lefigaro.fr, I discuss what we learned from past Ebola epidemics and travel restrictions. www.lefigaro.fr/sciences/pas...

On May 22 WHO reported 1 more #hantavirus case linked to the MV Hondius, while some high-risk contacts are still being located. We estimated that heterogeneous isolation + uncertainty on pre-sympt transmission leave a non-negligible risk of secondary clusters. Work led by @eugeValdano.

Our recent analyses on the international dissemination risk associated with the current Bundibugyo Ebola outbreak in eastern DRC are discussed in @lemonde.fr today: www.lemonde.fr/planete/arti... #SUMOC @inserm.fr @fac-sante-sorbonne.bsky.social

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):

1/ Yesterday I was more worried about #hantavirus than I am today. Why? Flight attendant who was exposed - Tested negative Viral genome - No concerning mutations Two Singaporean's exposed - Tested negative Data situation - We're tracking at Global.health (h/t @mugkraemer.bsky.social)

The #hantavirus outbreak onboard the MV Hondius is an rapidly evolving situation. Here are some takeaways from the #WHO press conference today. A key one for me: the US and Argentina, both recent WHO dropouts, are cooperating with the WHO-led efforts. www.statnews.com/2026/05/07/h...

It is our great pleasure to announce this year's Erdős-Rényi Prize winner! Laurent Hébert-Dufresne @lhd.bsky.social

Big congratulations to the Euler Awardee of 2026: Albert-László Barabási @barabasi.bsky.social

We are delighted to announce this year's Outstanding Service Award winner: Yamir Moreno @ymoreno.bsky.social

A big round of applause for this year's Fellows: Filippo Radicchi, Tiziana Di Matteo, Stefano Boccaletti, Piet Van Mieghem, Dmitri Krioukov, Lise Getoor, and Danielle Bassett.

Per-contact transmission risk was previously estimated as 3.4% in household (pubmed.ncbi.nlm.nih.gov/17471425/), so below could imply [big assumption] a single case on average infects roughly 20x0.034 = 0.7 others per day infectious on cruise. Can see why cluster can occur.

Since there's taboo around this, suggesting that cases of Andes virus may be caused by human-to-human transmission on a cruise ship is entirely uncontroversial: 1️⃣ We already know it's able to. 2️⃣ Conditions are "optimal". 3️⃣ This doesn't change the fact that a larger outbreak is extremely unlikely.

Joseph Tsui, Ben Reddy and I are recruiting a postdoc @psioxford.bsky.social to work on AI methods for multi-pathogen and multi-country biosurveillance optimisation for epidemic and endemic pathogens. Closing date May 11th my.corehr.com/pls/uoxrecru... www.pnas.org/doi/10.1073/...
