Lying-in women (maternity) & the ‘offensively’ sick: 1,200 cubic feet (34m3 ≈ 14m2 floor area)
(source: Healthy Houses, 1876)
& it gets better
..the book was written by William Eassie, “late assistant engineer to Renkioi Hospital during the Crimean War”
Renkioi Hospital (1855) was a prefabricated hospital, designed by Isambard Kingdom Brunel with “the necessities of hygiene: sanitation, ventilation, drainage & temperature controls.. integrated in 1,000-patient hospital layout, using 60 of the unit wards” en.wikipedia.org/wiki/Renkioi_H…
& it happened due to the advocacy of “the splendid spinster” Florence Nightingale who reformed hospital practices & conditions (including ventilation to prevent disease spread) cpb-ca-c1.wpmucdn.com/sites.uoguelph…
who said that “If infection exists it is preventable. If it exists it is the result of carelessness, or of ignorance”
& Florence Nightingale designed windows to ventilate rooms without draughts.. & hospitals with adequate space & ventilation for public health scientificamerican.com/article/what-f…

🇮🇪 Covid Inquiry- my comments didn’t all make it into @Independent_ie today 🧵 1/
“Over 9,600 people have died from Covid-19 in Ireland, including one hundred & forty one in the weeks since Christmas… independent.ie/irish-news/pub…
..involving 31 residents. The pandemic is not over. An estimated 10% of those infected suffer long-term effects, & this burden of illness continues to grow.
Therefore, it is likely too soon to evaluate much of Ireland’s response. Decision-making is in the same hands… 2/
However there are meaningful questions that can be asked to improve current response & future-proof Ireland against repeat of this crisis.
Firstly the scientific failure –then & now– to acknowledge how the disease spreads.
Covid-19 is airborne & no amount of hand-washing.. 3/
(from 2021): “growing body of research on COVID-19 provides abundant evidence for the predominance of airborne transmission. This route dominates under certain environmental conditions, particularly indoor environments that are poorly ventilated” 2/ ncbi.nlm.nih.gov/pmc/articles/P…
“These viruses can be spread by an infected person simply by breathing. And like cigarette smoke, these viruses can linger in the air for hours in poorly ventilated spaces”
[Thread] a short story about pandemic misinformation & biased reporting
On 1 April 2021 I was contacted by a newspaper journalist.. 1/
..the journalist attached the reply received from HSPC (who collect Covid data)
It DID NOT say 1 in 1,000 cases
It gave very limited data about *42 outbreaks* investigated by HSE
It reads as someone being helpful guessing at what might be outdoors (construction, sport etc) 2/
..vast majority of Covid cases are not connected to outbreaks..& capacity to investigate outbreaks is also very limited
The journalist took a guess at *42 outbreaks* (262 cases) ..& erroneously related it to total number of cases at that time (236,600 cases, 1 April 2021) 3/
No two schools are same & conditions vary from room to room & from hour time hour
Statistically there’s an infectious child in EVERY class now, so a classroom has same risk as an isolation ward in a hospital. This is a very high risk to manage 1/
🚦 CO2 (carbon dioxide) monitors are in schools to measure exhaled air. (They don’t measure virus)
..the more people breathing, the more CO2 build up
.. the more exhaled air, the more chance of inhaling virus particles
So more clean air & fewer people reduces the risks 2/
🚦@Education_Ire guidance suggests >1500ppm is ‘poor ventilation’ but in a pandemic this is too high (3% of every breath is not clean air)
Recommended is <800ppm (<1% of every breath is not clean air)
