Big @batsgoviral week! In @PNASNews and @ScienceAdvances we test how to prevent zoonotic #spillover by interrupting virus transmission in bat reservoirs. Short story: culls didn’t reduce spillover but altered rabies spatial spread; transmissible vaccines may be a solution. A 🧵. 
First culling. Vampire bats are poisoned throughout Latin America to reduce blood feeding on humans and livestock and in hopes of preventing uniformly lethal rabies infections. Whether culls reduce rabies spillover is still controversial even after ~50 years of use.
We studied a 2 year bat cull in southern Peru where >21,000 bats were treated with a spreadable poison #vampiricide. This region suffered >1000 rabies outbreaks from 2003-2019 making a rare & statistically powerful case study to test whether bat culls reduce viral spillover.

"Trotz einer Flut sensationeller Berichterstattung in den Medien, die darauf hindeutet, dass die #Pandemie als #Laborleck begann, stützen die Beweise mit überwältigender Mehrheit ein zoonotisches Übergreifen."

"Um das Übergreifen von #Viren zu untersuchen, braucht man mehr als nur Virologen. Für diese Arbeit benötigen Sie internationale Kooperationen mit fachübergreifendem Fachwissen."
"Es ist kompliziert. Es ist komplizierter als „Wow, was für ein heikles Problem, es ist genauso wahrscheinlich, dass wir es vielleicht nie erfahren werden🤷🏼♀️.“ Außer, dass wir wissen, was die Beweise darüber zeigen, wie diese #Pandemie begann."
Transition spillover risk means decarbonization in trade partners can negatively shock fiscal and financial stability. When it compounds with physical risk, shocks amplify. We present today results for #Barbados at @AFD_en Strong Sustainability conference bit.ly/3P9xCto
We design and assess scenarios that combine acute and chronic physical risks, building on CLIMADA and NGFS scenarios downscaled to Barbados
we then extend the concept of #transition #spillover #risk as shock from carbon price on international flights and IEA Net Zero scenarios for aviation and we assess transmission channels to econ and finance agents, fiscal and sovereign financial stability, using EIRIN
First, kudos to the Chinese authors doing this work & a shoutout to @edwardcholmes also involved
I already flagged this Wang et al. preprint yesterday but it is worth explaining its significance to both the #origins discussion and the related pandemic #prevention discussion

First: Origins
One thing that goes often down in all the noise surrounding #lableak is the fact that SARS-CoV-2, and actually all CoVs, possess #mosaic genomes.
This is because CoVs evolve not only through mutation but also through exchanging genetic elements with other CoVs

This exchange is called '#recombination'.
One can imagine CoV genomes like colorful Lego brick walls, and recombination as taking one brick from a different virus and putting it in the wall of another; changing the color while keeping roughly the function.

Cominciamo dalla missione dell'#OMS a #Wuhan, all'inizio di quest'anno. Qui trovate il rapporto finale che considera "estremamente improbabile" l'incidente di laboratorio. 2/

One last thread on the origins of #SARSCoV2 before the upcoming publication of the US intelligence report. First of all, there are two things that might be even more important than the origin itself: research ethics and scientific debate. 1/
Since the beginning, some scientists working in Chinese institutions haven't been fully transparent. The history of #RaTG13 and the issues with its sequencing data, the miners pneumonia, the missing database, the pangolin CoV data. Hiding info, playing with words. Bad science. 2/
The second thing that I didn't like was the suppression of an open dialogue between scientists, which lasted for several months. Now it's easier for scientists to freely talk about the different scenarios, but do you remember how difficult it was one year ago? 3/

Se #SARSCoV2 è naturale, esiste un animale portatore, cioè animale in natura infettato da un virus quasi identico a quello umano. Non vale 92,4% del #coronavirus nei pangolini malesi, né 96,2% del virus trovato nei pipistrelli ferro di cavallo. Punto. 2/
Come per le scale in Harry Potter, anche ai virus piace cambiare. Pipistrello e pangolino potrebbero essere “serbatoio” naturale, da cui #SARSCoV2 è arrivato a noi, attraverso varie mutazioni e salti di specie intermedi. Il punto è ricostruire la mappa degli eventi. 3/

Immaginate la vostra palazzina inondata dall’acqua, causa un tubo rotto. Di domenica. Agosto. Prima delle ferie. La frustrazione di quel momento può portare nostro cervello primordiale a cercare e creare una risposta. "Colpa del vicino invidioso, il tubo passa nel suo muro!" 2/
È uno scenario abbastanza improbabile, no? Anche la casa del vicino è inondata! Ecco, credere all’ipotesi del virus creato in laboratorio e volutamente messo in circolazione non è diverso da questa storiella. Aggiungiamo però anche altri aspetti su sequenza di #SARSCoV2 3/
A #thread on our recent paper in @PLOSNTDs examining ecological #evidence-base for #DiseaseControl management practices for #KyasanurForestDisease #AcademicTwitter #Scicomm #OneHealth; paper led by @SarahBurthe from @MonkeyFever_ consortium
#Diseasecontrol strategies originate through endorsements by Governments/academia/authorities; they're often not field-tested robustly; even when they are, evidence is limited to one sector (cf. #OneHealth #Intersectoral approaches);
#publichealth approaches ought to be contextual & their effectiveness ought to be evaluated, yet strategies for disease control often spread through word of mouth and are sometimes untested;

Global shifts in mammalian population trends reveal key predictors of virus spillover risk. Out in Proc Royal Society B @RSocPublishing @CKreuderJohnson @EpiCenterUCD @PREDICTproject @OneHealthUCD @ucdavisvetmed @LairmoreDVMDean @NIH doi.org/10.1098/rspb.2…
Co-authors include @petaleeh @PanditPranav, @SmileyTierra, Julie Rushmore, Cristin Young, and Megan Doyle. The study was supported by @PREDICTproject and @NIH
The study concludes that the exploitation of natural habitats is not only a conservation issue, but an important driver of spillover transmission zoonotic viruses. Here is a thread that discusses three key points highlighted from study.
