If you’re wondering why so many people are sick right now, here’s your answer👇🏻 People infected with Covid exhale high amounts of virus during the first 8 days after symptoms start, as high as 1,000 copies per minute - even those with only mild symptoms. news.northwestern.edu/stories/2023/0…

Henry Burridge Prof Cath Noakes #Ventilate 😷 💙 SAMHE Project Henry, I know you are heavily involved in the SAMHE project. I’m a huge fan of this project & think it has enormous potential to drive change. However, I have concerns about the way the data is currently presented as averages of averages, as I explain in my thread below ⬇️

Henry Burridge SAMHE Project Hi Henry, please could you help clarify what this chart is telling me to ensure I’m not misinterpreting the data? Is this telling me that, when the temperature is 5°C or below, it would be expected that at least 20% of classrooms would have a mean daily CO2 exceeding 1500ppm?

Henry Burridge SAMHE Project Hi Henry, given that you were showcasing your new model for assessing ventilation rates in classrooms, would a better headline conclusion for this paper be: ➡️ Whenever mean daily outdoor temp dropped below ~12°C, ventilation in classrooms fell BELOW the recommended minimum.

Henry Burridge SAMHE Project Hi Henry, sorry I have another question… Please can you explain the difference in the data between the two charts here? I believe both charts illustrate the full data set. I’ve added the colour bands to help illustrate the large differences in the values on the y-axis.

Henry Burridge SAMHE Project Hi Henry, I’m struggling to reconcile this finding… ▪️A QUARTER of schools (48/190) had daily mean CO2 readings exceeding 1500ppm for >25% of days of the term. …with this reassuring statement: ▪️ “Most schools-days of exceedance come from just a few schools”.

Maarten De Cock Henry Burridge SAMHE Project Henry, I just want to return to this point below… ⬇️ If you genuinely agree that a mean daily average of 1500ppm (which includes all the times when classrooms are unoccupied) is *NOT* an acceptable target to aim for, why does your paper focus so heavily on this single metric?

Last month #ThereForME sent a letter to Wes Streeting MP signed by 2,600 #ME #LongCovid patients & carers. On Friday we received a response. We’re disappointed he did not respond to us in person or commit to a meeting. We think patients deserve better. thereforme.uk/p/campaign-upd…

Our govt should be legislating for safe hospitals. Unions should be pushing for it. Grassroots staff should be calling on their unions and large charities involved with health should be too. Protecting staff and patients should not be a fringe concern!

Karen Hargrave Wes Streeting MP The letter from Andrew Gwynne MP says the Government are working to change the NHS into an organisation that not only treats illness, but prevents it. How can that be true when the Government is making no effort to reduce Covid infections? Clean air in schools would be an easy win.

Snippets from Module 3 Opening Statement, by J Carey KC, Counsel to the Inquiry “..if one pauses to think about an old hospital ward with multiple beds and windows that don’t open and aging ventilation systems, one can see how important ventilation is in healthcare settings..”

SAMHE Project DAERA Education Business Explorify Association for Science and Discovery Centres Secondary Students’ Union NI WeLearnNI STEMHubNI University of York Outreach Children & Young People's Mental Health Coalition Donna Hanley I’d like to raise a query about Q8 on p22 of the Teacher Activity Guide. My son is clinically vulnerable. If the CO2 is 2,000ppm in his class of 30 kids, some of whom have Covid symptoms but been told it’s ok to still attend school, would you really consider it “safe” for him?

Crikey, the guide says a CO2 reading of 2000ppm is "not necessarily harmful". necessarily doing a lot of heavy lifting there in an ongoing, institutionally denied pandemic 🧐

I'm so happy to be able to share this! It's SLIGHTLY dominated life over the summer - my house is a tip, the kids were abandoned & had to work on holiday.. but it's out. Just trying hard to achieve better air quality for kids in school. #CleanAirNow safeairschools.org

A UK government-sponsored guide is telling teachers it is safe “if the CO2 level in your room is 2000 ppm” (!) 🤷‍♂️ Do you agree with this Henry Burridge? SAMHE Project HT: Cat in the Hat 🐈‍⬛ 🎩 🇬🇧

So about once a minute, they fill their lungs with air straight from another kid's lungs. Humans emit 1000 viral copies per breath in the first 8 days of Covid infection.😩youtu.be/nLHdbGZtkj8?si…

LONG COVID 💥 Healthcare workers WITH COVID-19 had 7 TIMES MORE SEVERE ILLNESS than NON-COVID-19 respiratory illnesses, and 8.8% of COVID cases had LONG-LASTING SYMPTOMS vs. 3.7% in NON-COVID cases. Great thanks for this study to thetranscendedman journalofinfection.com/article/S0163-…
