Still about the paper (royalsocietypublishing.org/d…).
Some didn't manage to listen to the audio summary.
Here it is, embedded in the post.
I am still amazed what AI can do with a simple PDF an a prompt "Give me and audio summary, podcast style." 🤯😀

Our latest paper is finally out:
“An integrated airborne transmission risk assessment model for respiratory viruses: short- and long-range contributions” in the

It’s with great pleasure that I’m invited to talk at this official event of the French #G7 Presidency and side event of the World Health Assembly on the importance of clean indoor air.
We have clean water, clean food and yet clean air seems to be lagging behind... Even though the air that surrounds us is what keeps us here, in this pale blue dot, one breath at a time!
Thank you Geneva Health Forum , Air Club , Irène Kostenas for the invitation - looking forward.

The High-Level WHA Side Conference on Indoor Air Quality is now an official event of the French G7 Presidency.
This recognition means that the event is acknowledged as contributing to the priorities and international outreach of the G7 Summit.

Something I touch on repeatedly in my Airborne Infection course is that “close contact” is not a good way to describe how a virus is transmitted. It can be communicated as a risk factor for infection, but it does not say what the actual biological mechanism of transmission is.
May 9
Earlier today I spoke with the doctor on the ship and he confirmed something. CDC messaging continues to say "prolonged, close contact" but that contradicts: 1) what's in the literature, and 2) what's happening on this ship.
--> the doc told me a few who got infected/died DID have direct contact w/ very sick patient while treating them, but 3 who tested positive did NOT have direct physical or close contact - only shared time in a few spaces on the ship where people congregate (dining, lecture area)

Today, Switzerland observes a National Day of Mourning in memory of the victims of the tragic fire that occurred on 1 January in #CransMontana.
Our thoughts are with all those impacted, in Switzerland and beyond.

Previously, it was widely assumed that close contact was the most important factor in the transmission of respiratory infections (such as Covid, influenza, etc.). However, this longitudinal study in Swiss schools demonstrates that this assumption is incorrect. Instead, prolonged

Since 2020, we’ve learned a tremendous amount about the airborne transmission of disease. Yet, in many ways we’ve just begun to scratch the surface.
This document came out of the WIAC conference held this summer. In it, many of the fundamental questions before us are proposed.

🇪🇺🤝🇨🇭 Switzerland is officially in the European research game.
Today, it joins Horizon Europe and the Euratom Research and Training Programme.
Think CERN-level breakthroughs… but across health, energy, and digital tech.
Here’s why it matters ↓

Politics, science, associations, civil society – we can all do more for healthy indoor air. @Genevaforum & partners are working on a WHO resolution for indoor air. At the 16th Climate Day of FGK, I had the opportunity to present this project and more in Marburg. #TheAirWeBreathe

Gestern hat @IKostenas in Marburg auf dem Klima-Tag etwas sehr Kluges gesagt.
Sie hofft, dass es Gelder geben wird, um die Bevölkerung über die Schadstoffe in der Luft und über #Lufthygiene zu informieren, damit aus der Bevölkerung der Wunsch nach Lufthygiene wächst.

Here's another great video from @ukhadds this time on airborne transmission models. Check it out and subscribe to his channel, a lot of interesting science explained 👇
P.s. gotta love his t shirt 🍁

When scientists say things like, "opening a window lowers the risk of transmission by 38%", where do they get these numbers? Well, they use airborne transmission models.
In my latest explainer video I walk through the history of these models, what they do, and what the don't.
