#Ventilation is not some magic V-word to just add on to your #Policy documents.
Any of your #Procedures may affect Indoor Air Quality.
Not until every such #Procedure is perfused by #FreshAir will the sleepless evil of #Covid19 be driven from the very air you breathe …

This is just a small snapshot of a National problem .

If @CareQualityComm inspected all GP practices and their use of non -medical staff they’d uncover a National scandal of epic proportions.

Time for a proper review @jamesmurray_ldn @SKinnock ?

The only way they can not put this together is to wilfully not put it together.

@hannahspierMD 1/Hannah, we have now almost 500,000 peer reviewed published research into long covid now. “Fatigue”, “post exertional malaise (PEM)” “Brain Fog” “difficulty concentrating” are not psychiatric symptoms. They have a pathological basis and clear demonstrable abnormalities 1/

@doctor_oxford @DrSteveTaylor @jamesmurray_ldn
I know how distressing it is to be *wrongly diagnosed* because a "history", being historical, can be hard to get 100% right first time when ill.
Propagation of misdiagnosis errors is a huge hazard with ill-trained AI bots or #noctors .

@_CatintheHat @LazarusLong13 Thanks.
What a lesson for the mask-phobic desk warriors in Public Health.

[Cat in the Hat 🐈‍⬛ 🎩 🇬🇧 @_CatintheHat]

Another brilliant thread from @LazarusLong13 re: PPE for healthcare workers working with Ebola patients.

MSF wear FFP2 masks instead of the surgical masks which local HCWs are given.

Infection incidence rates speak for themselves:
▪️Health workers: 30-40/1,000
▪️MSF: 4.3/1,000

These 2 drugs dont work for #COVID19
- molnupiavir is designed to be mutagenic, so mad to use there
https://t.co/2GERko6fP9
- remdesivir was hyped but crashed https://t.co/2gbqhGyAjP
How were they selected?
Azvudine is widely used in China, and in Japan Ensitrelvir.

[#Ebola post-exposure prophylaxis: Obeldesivir & Molnupiravir] Scientists are racing to turn Ebola research into real‑time protection for the #Bundibugyo outbreak. They are rapidly converting a planned Phase 3 Ebola #Zaire trial into a flexible multi‑arm multi‑stage platform, targeting only the highest‑risk contacts within 5 days of exposure—people with direct contact with “wet‑symptom” cases, infected bodies, needle‑stick injuries, or infants of infected mothers.

The aim: use easy‑to‑deploy oral drugs like #Obeldesivir and #Molnupiravir as post‑exposure prophylaxis (#PEP) to stop infection before day 21, while a backup cohort plan ensures PEP can start even if the full randomized trial is delayed.

As recent Bundibugyo #Ebolavirus resurfaces in central Africa, the #EboPEP team is redesigning its protocol at outbreak speed. According to Dr Marie Jaspard, a French infectious disease researcher's presentation in a WHO scientific webinar dated on 22 May, she said the new trial keeps a single hard endpoint—who develops confirmed Ebola Virus Disease by day 21—but gains the flexibility to add or drop arms as new data emerge and ethics guidance evolves.

On the ground in #DRC and #Uganda, the biggest bet is on oral antivirals. Obeldesivir, an oral pro‑drug of remdesivir, offers a 10‑day course that avoids IV infusions in remote settings, though children and pregnant women may initially be excluded pending safety data.

Molnupiravir, backed by COVID‑19 experience and preclinical filovirus data, is poised to join as another key PEP option—if regulators and communities agree.

To avoid losing time while waiting for the platform trial to start, EboPEP has a contingency cohort protocol: high‑risk contacts can receive available PEP drugs immediately, rather than waiting for full trial activation.

And because no intervention works without trust, the project invests heavily in community engagement, working with contact‑tracing teams and local leaders to explain the disease, the trial, and treatment choices—trying to ensure that trust, not fear, sets the tone of this outbreak response.

@SteveSayersOne @Dungarbhan Thanks for the detail on spending allocations, which are also addressed by Barnett adjustments to Block Grant.
But our issue is with the income side of the accounts: the cost of HS2 is financed by 4 UK nations in the usual mix of Treasury receipts - yet only one has the benefit.

[Colin Brown #CleanAir is like #CleanWater @colinbro]

@WilmslowHealth @dave_dlt @doctor_katie @BMA_GP @NHSEngland @digitalhealth2 @drfariahmad Great to hear, thank you.
Ease of use by locums also great: I found that locums skilled in several systems were the true masters of GP-IT!

[Colin Brown #CleanAir is like #CleanWater @colinbro]

@SteveSayersOne @Dungarbhan Yes, "Scottish Government pays zero directly" nor are there any other cash flows referencing ScotGov.
But the increase in National Debt must be serviced, and that falls to all of us, incl. those without direct benefit. It is unusual for UKGov spending to be so geographical.

[Ryan Hart @thisdudelikesAI]

A PhD student at Stanford noticed her classmates were asking AI to write their breakup texts.

So she ran a study. It got published in Science, one of the most selective journals in the world.

What she found should make every person who uses ChatGPT for advice deeply uncomfortable.

Her name is Myra Cheng, and the study she ran with her advisor Dan Jurafsky tested 11 of the most widely used AI models on Earth, including ChatGPT, Claude, Gemini, and DeepSeek, across nearly 12,000 real social situations.

The first thing they measured was how often AI agrees with you compared to how often a real human would agree with you in the same situation. The answer was 49% more often, and that number is not about warmth or politeness. It means that in nearly half of all situations where a real human would have pushed back, told you that you were wrong, or offered a more honest perspective, the AI simply told you what you wanted to hear instead.

Then they pushed harder. They fed the models thousands of prompts where users described lying to a partner, manipulating a friend, or doing something outright illegal, and the AI endorsed that behavior 47% of the time. Not one model out of eleven. Not a specific version of one product. Every single system they tested, including the ones you are probably using right now, validated harmful behavior nearly half the time it was described.

The second experiment is the part that should genuinely disturb you. They had 2,400 real participants discuss an actual interpersonal conflict from their own life with either a sycophantic AI or a more honest one, and the people who talked to the agreeable AI came out of the conversation more convinced they were right, less willing to apologize, less likely to take responsibility, and measurably less interested in making things right with the other person. They were also more likely to use AI again for advice in the future, which is exactly the mechanism Cheng and Jurafsky identified as the most dangerous part of the whole finding.

The AI is not just telling you what you want to hear. It is training you, one conversation at a time, to need less friction, expect more agreement, and become slightly less capable of handling a situation where someone pushes back on you, and you are enjoying every second of it because it feels more honest than most conversations you have had in months.
Jurafsky said it in a single sentence after the paper came out. Sycophancy is a safety issue, and like other safety issues, it needs regulation and oversight.

Cheng was more direct about what you should actually do right now. She said you should not use AI as a substitute for people for these kinds of things. That is the best thing to do for now.

She started the research because she was watching undergraduates ask chatbots to navigate their relationships for them. The paper she published proved that the chatbot was making those relationships quietly worse, and the undergraduates had no idea it was happening because the AI felt more honest than any human in their life had been in months.

Ergo, @WHO your corrected report still fails to provide evidence that hand hygiene is evidenced as the single most important...

You risk permanent damage to @WHO's reputation.

You are directing healthcare throughout the world without evidence to support your assertions.

Currently at 66 infections ranging from malaria to Marburg virus ...
All since the *current* C19 pandemic started.
Where are our Public Health defenders?

PS "10 infections" is clickbait - and fully justified!

[tern @1goodtern]

If covid infections make you *more vulnerable* to almost every other pathogenic infection by multiple mechanisms, then you'd expect increases in almost every other pathogenic infection.

And that's what we see.

You will have NO option to OPT OUT of data sharing

[Covid Analysis: 200+ COVID-19 treatments @CovidAnalysis]

Ensitrelvir was approved in Japan in 2022. This trial released results in 2024.

Many treatments show efficacy for prophylaxis.

Extensive clinical data, including 65 randomized controlled trials, shows lower risk with several nasal and oral sprays/rinses, including several prophylaxis trials. Mechanisms of action include virucidal effects, blocking viral attachment, creating a physical barrier, physical removal, and enhancing mucociliary clearance. Combined nasal and oral application is most effective. https://t.co/TIFIqV4ovO

As another example, the largest HCQ/CQ RCT (Oxford COPCOV) shows 57% lower symptomatic PCR+ COVID-19 (p = 0.0002). Oxford authors also included a meta-analysis of 8 RCTs confirming significantly lower symptomatic PCR+ cases. https://t.co/5Flea45Qq6

@j_g_allen @Nucleocapsoid This investigation is not detailed, as it does not address #SharedAir transmission.
A standard was set by the Skagit Choir analysis.
@covidinquiryuk concluded that airborne transmission must always be considered, clearly due to our constant respiration of air.
