[Thread] 🇮🇳 #India Prevention

#Covid19 is mostly caught by breathing infected air, not from hands

😷 Wear well-fitting masks everywhere indoors

🍽 Eat & drink outside & at a distance

🪟💨 ventilate rooms/vehicles, keep airflow moving at all times, open doors & windows 1/
🌀turn off or limit use of air-con units that recirculate cool, dry air

💦 avoid low humidity in air-con rooms (showers & cooking add moisture)

🛏 avoid shared bedrooms, partly open windows & doors for night airflow

🚙 🚌 open windows, turn fans to full fresh air & mask 2/
Why is air-conditioning higher risk for #Covid19?

🥶 virus survives longer in cool, dry air
🐪 nose mucus dries out & people are less protected
💨 less fresh air is brought in (to save energy)
📦 rooms/cars are sealed, & so virus is trapped & builds up like invisible smoke 3/
🌳 Breath outdoor air & at a distance from others where possible

🏠 🚎 Avoid shared air, limit time in shared spaces, wear well-fitting mask inside

😷 😷 Double mask (cloth mask on surgical mask) where possible for filter & fit. Use respirator N95/FFP masks if available /4
⚙️ Buy or DIY portable filtration fans (HEPA/MERV13) to remove virus & pollution from indoor air

📟 Use CO2 (carbon dioxide) monitors to measure & prevent unsafe indoor air conditions (avoid CO2 above 800ppm, &/or low humidity) 5/

🇮🇪 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)
