🇮🇪HSE #Covid19 information is unscientific & unsafe. People are at risk of infection due to misleading, contradictory & out-of-date advice 1/
✅Covid19 is MOSTLY spread by aerosols from breathing & talking, NOT droplets from coughs & sneezes
✅Aerosols linger & spread >2m
✅ ‘social distancing’ of 2m is NOT a protection indoors, everyone breaths the same air
✅ virus can fill rooms & linger for hours in EMPTY rooms/lifts/vehicles
✅ risk from touching surfaces/hands/eyes is LOW
✅ respiratory virus are almost always INHALED by infected air 2/
✅ ventilation & filtration are critically important in ALL buildings & vehicles, whether crowded or not
✅ crowded indoor spaces are unsafe BEYOND 2M DISTANCE
✅ wear a mask EVERYWHERE INDOORS that isn’t your home
✅ cough & sneeze INTO YOUR MASK
✅ NORMAL cleaning is fine 3/
✅ clean hands are good for health, & may prevent some #Covid19 transmission.. but hands CANNOT (mathematically) control this pandemic
✅ Clean indoor air, good masks & vaccines CAN control this pandemic
✅COVID IS AIRBORNE (this has been known since Spring 2020) 4/
People at risk (medical conditions/disabilities/older people)
✅ nobody knows their own immune response to a vaccine.
✅everyone should LIMIT EXPOSURE to unsafe conditions
✅ Risk is about places not people
✅ ALL places can be made low risk for EVERYONE www2.hse.ie/conditions/cov…
Nursing homes
✅ Outbreaks can be PREVENTED with airborne precautions
✅ WELL FITTING MASKS should be everywhere indoors.. & ESPECIALLY in close contact/in vehicles with vulnerable people
✅ DON’T TEST IMMUNITY. Vaccines don’t block infection, people may have waning immunity now
[aside: outdoor visits & “window visits” are inhuman & completely unnecessary. I wrote advice for safe visits to nursing homes one year ago. It wasn’t adopted]
People who are infected (& sharing a home)
✅wear well-fitting masks
✅avoid shared rooms/bedrooms & cars (esp mask off to eat)
✅ventilate shared spaces (incl bathrooms/halls)
✅keep trickle of airflow at all times for cross ventilation
✅use plug-in HEPA filter fans if possible
tl;dr
Everyone wants to be safe. Tell them how
Vaccines help fight infection, but nobody knows how well a body works. Avoid exposure
🇮🇪 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)
