thread with Google Translate, HT @DzungLeVN for link) 1/

‘Hospitals use ventilation one-way to avoid cross infection’ 2/ Image
‘This is considered one of most modern facilities in Vietnam to treat #Covid19 patients. The hospital is in 3 zones
🟩 Green area- administration
🟨 Yellow area- dormitory, canteen, testing & equipment
🟥 Red area- treatment’ 3/ Image
‘Treatment area consists of 500 beds... 9 VIP (single rooms?), 20-bed blocks for severe & critical patients, 38-bed blocks for patients with mild symptoms’ 4/ Image
‘all project units (bed spaces) are ready to install medical equipment.. partitions, oxygen supply, monitoring camera, ventilator, AIR PURIFIER & other machines’ 5/ Image
‘all wards are equipped with a camera system to promptly monitor patients progress. The hospital will be operated, monitored & consulted remotely’ ( to reduce risk to staff?) 6/ Image
‘leading hospital for air conditioning to treatment rooms..one-way VENTILATION SYSTEM to limit spread of virus & prevent cross-infection

At head of bed there will be system to suck exhaust gas from patient.. specialised FILTER at air intake.. ULTRAVIOLET LIGHT to treat virus’ 6/ Image
‘system of 360 specialised AIR PURIFIERS to decompose, inhibit mould & neutralise viruses by 99%’ 7/ Image
‘roads around hospital marked “clean” & “unclean” lanes (low & high risk areas).. BUFFER ZONE of 69 disinfecting bathrooms & green spaces. People entering & leaving treatment area must undergo disinfection steps (again, protection of staff?) 8/ Image
‘Liquid oxygen storage tower with capacity of 16m3 ensuring supply for all patients.. each of these towers will be sufficient for 2 days’ 9/ Image
‘construction work 3 consecutive shifts.. “one route, two destinations” to ensure limited contact & avoid risk of infection’ 10/ Image
‘When operational (in coming weeks) there will be 1,000 medical staff.. nearly 300 doctors & 700 nurses’ 11/ Image
[aside: yes, the construction company really is called Delta deltacorp.vn/en/general-con… ] 12/ ImageImage
‘hospital is isolated from residential areas to ensure safety’ /13 Image
‘by 29 August (yesterday), the project had completed 95% of construction..it is expected to be inaugurated 31 August & after 3 days will start accepting #Covid19 patients’ /14 Image
foundations of the 500-bed hospital that will have patients this week were completed on 31 July 2021 (yes, 1 month ago) /15 Image

🇮🇪 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/

“Sick of your kids being sick? Clean air in schools may be the answer”

Co-written with @j_corey02 in @irishexaminer today

🧵of links to research mentioned & more information for parents & teachers #Schools #EdChat #EdChatIE 1/
(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/ Image
..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/ Image
..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/ Image

#Covid19 Schools, what to do?

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)

Outdoor air is ≈420ppm (very low risk unless close)
