During the Covid inquiry, one of the independent expert witnesses was asked: “Is there any scenario or situation where someone could produce a droplet without also generating significant amounts of aerosols?” Professor Clive Beggs clearly replied: “NO”.

Here’s the pupil & teacher illness absence charts side-by-side ⬇️ 🔎 In 2024/25, pupil illness absence was still nearly 30% higher than pre-pandemic norms. 🔎 In 2023/24, teacher illness absence was nearly 40% higher than pre-pandemic norms (2024/25 data won’t be published until this June).

By Cat in the Hat @catinthehat.bsky.social "Health officials are even actively telling people NOT to wear a mask to protect themselves because they can “create the wrong message” and “spread panic”. "If there is even a chance of AEROSOL transmission, this could be extremely dangerous advice."
Screenshot of a social media post by Cat in the Hat (@_CatintheHat) discussing mask guidance. Below is a Kidney Care UK article titled “Should face masks be worn?” with highlighted text stating: “The UKHSA do not advise wearing face masks as they have no role in controlling meningococcal disease outbreaks.” It also quotes that masks can “create the wrong message” and “spread panic,” and concludes that “for the public there is no need to wear a mask,” noting meningococcal disease spreads differently from COVID-19.

This whole thread. It’s criminal that the UK, in the middle of a meningitis outbreak that has killed 2 students, put many in hospital and still a danger, is repeating the same droplet dogma mistake they did with Covid, which has been admitted in a long-drawn out Covid Inquiry was a colossal mistake👇

The Covid Inquiry Module 3 report has ordered that: “In future, guidance should assume that ALL plausible routes of transmission are possible until sufficient evidence proves otherwise.” There are no excuses anymore. The govt MUST NOT make the same mistakes again. We MUST learn from the past.

The Covid Inquiry Module 3 report published just this week made it clear that it is no longer appropriate to rely on the outdated dichotomy between aerosols & droplets. Where there is droplet transmission, there is also a high probability of aerosol transmission.

A key finding from the Covid Inquiry report published this week: “Guidance on preventing the spread of infection was flawed. It assumed the virus was spread by CONTACT transmission, failing properly to consider the extent to which it was also spread by AIRBORNE transmission.”

Instead of telling people *not* to wear masks, public health officials should be educating people about the right types of masks to protect against AEROSOL transmission. 😷 Surgical masks do not protect against aerosols. 😷 Only FFP2/3 masks provide adequate protection. whn.global/a-call-for-t...

…so it seems strange that the authorities are pushing so hard on the narrative that it only spreads by very close & intimate contact eg. living together, kissing, sharing drinks. In their efforts to ‘reassure’, they’re failing to educate people about how to protect themselves.

On this day, 13 March 2020, six years ago, the UK government made a "pragmatic" decision to downgrade Covid from High Consequence Infectious Disease (HCID) due to the shortage of FFP3 masks. This left NHS workers unprotected from Covid since. Thanks to @catinthehat.bsky.social for the reminder & 👇
Letter by Prof. Tom Evans, chair of the Advisory Committee on Dangerous Pathogens (ACDP) to the UK Deputy Chief Medical Officer Jonathan Van Tamm on 13 March 2020 recommending that Covid-19 should NOT be classified as a high consequence infectious disease (HCID). The letter is juxtaposed with an extract from 6 February 2021 article by the BBC science editor David Shukman about the consequences of that decision. The subheader says 'A "pragmatic" decision. Highlighted text reads: 'A member of ACDP, speaking on condition of anonymity, said the decision was indeed "pragmatic", not because of pressure from government but because everyone knew the stockpile of PPE was limited'.

Many countries dealt with Covid 19 very effectively. The UK pursued the wrong strategies and failed miserably, with hundreds of thousands of deaths. Rather than learn the obvious lessons, the plan is to pretend there is no solution, and bestow honours on the architects of our negligent disaster.
