Ooh look at that, CO2 display monitors at the #ESCMIDGlobal2024 conference poster areas. Not packed but a fair few folks in here 👍

@JeremyFarrar It is bizarre that we are bracing for something that we know is going to happen rather than acting to prevent it.

But the scientists who remain puzzled are not those who work on transmission. Yes we still have questions on the frequency, variability and control of long range airborne transmission, but there’s no question that it happens. Ventilate, wear a mask.

Top scientists remain puzzled over how and why Covid spreads

The world may have multiple vaccines and drugs to fight coronavirus but we’re still not really sure about how it transmits or how to stop it

This was unexpected but a really nice surprise and I’m honoured to have been awarded the Gabor medal by the @royalsociety . But it should really belong to the huge number of people in the UK and worldwide who have worked so hard to understand the complexity of virus transmission.

Interesting study that associates using HEPA air cleaners with better cognitive performance in a set of standard tests. Some more useful evidence for the benefits of clean air

Indoors + lots of people + low ventilation + new variant = perfect recipe for new cases. Get vaccinated, use testing, stay home if you have symptoms, ventilate and keep your fingers crossed for the next few weeks.

A virus that’s 50% more transmissible could need 50% more ventilation to help control. The risk in a well ventilated building probably remains low, but if your ventilation is lower, chances are it’s no longer enough. Places that were “getting away with it” now need to act.

If your school, work, library, community centre is naturally ventilated, seriously consider investing in air cleaners for this autumn and winter. Even with higher elec prices they’re likely to be cheaper to run than opening windows and also trying to heat the place. 1/

Very pleased to see this finally happen. It’s been a long haul and is just the start of the ventilation journey we need to take

Schools in England are to be given CO2 monitors to as part of plans to limit the spread of Covid.

We have a choice over the next few weeks. We can either be cautious and get vaccinated to get cases lower, and fix schools and workplaces to be in a good place for September, or we can party the summer away and be in dire straits just in time for the mass return to work & school

Everyone ready for the next wave yet? Let’s just hope that summer ventilation and reduced contacts through outdoor interactions manages to suppress things…

@dgurdasani1 Airborne transmission is possible outdoors when people are close together. It’s a reminder that outdoors is safer but not zero risk when you’re interacting closely.

Today it’s #CleanAirDay so here’s a reminder that your indoor air is as important (if not more so) than outdoor air. We spend up to 90% of time indoors so most air pollution exposure happens inside buildings. But there’s lots you can do to reduce this 🧵 1/

Me and @DrSDFitzgerald in a new @guardian piece on school ventilation. Basically: Co2 meters ✅ Windows- get them open ✅ Mech vent ✅ Air cleaners - as long as it’s the right type in the right space ✅ Ozone decontam units ❌ Recirc air con ❌

This is a really good explanation of how an N95 mask works. It’s not just a sieve. And a lot of this also applies to 3 layer cloth and well fitting surgical masks too

As everyone gets excited about low cases, opening up and reducing measures, can we remember we’ve been here before? Low cases last summer became a massive wave by Christmas. Yes vaccines will reduce it, but there’s still a way to go. Please keep doing #HandsFaceSpaceFreshAir
