#NursingHomes important to know #Covid19 builds up & spreads like cigarette smoke; so closed windows in cold weather is making conditions high-risk for super spread- it can be easily mitigated by airing rooms (ventilation), air purefier fans (filtration) & checks with CO2 monitor

#Nursinghomes -use air filtration fan units to ‘clean’ virus from a room for <€100 (& diy options also work)

[Thread] Last night the Chief Medical Officer finally said #covid19 is spread “indoors in poor ventilation”

This is HUGELY SIGNIFICANT, & here’s why.. 1/ #Covid19 Image
..Ireland’s public health message is not in step with international scientific community & has not kept pace with 9 months of research.. so no warnings have been given about ~airborne~ virus spread that happens ~beyond 2m~
2/ ImageImageImage
..it’s now known this respiratory virus is caught from inhaling when breathing; risks from surfaces were over-stared so perspex screens & deep cleaning have distracted people from the most important prevention- ‘clean air’ (take 5 mins this is worth it) 3/

[Thread] Will #Level5 work?

Contacts between people are not all high-risk, & research says that most people with #COVID19 only transmit to 1 other person or fewer.. ‘It’s often not very contagious’ 1/

[ @jljcolorado cires1.colorado.edu/jimenez/COVID/… ]
..but a small number of people with covid (less than 20%) are likely infecting more than 80% of new cases... ‘preventing superspreader events could go a long way toward stopping COVID-19’ 2/

[ @svscarpino scientificamerican.com/article/how-su… ]
..Germany’s top doctor
‘Most people only pass it to one other.. occasionally, someone spreads more widely, creating a cluster of infections that drives the pandemic. To avoid another lockdown Germany must focus on identifying & preventing clusters’ bloomberg.com/news/features/… 3/

‘If you need to be right before you move you will never win’ @who Dr Mike Ryan
HPSC acknowledges airborne spread of #Covid19 virus beyond 2m in poor ventilation, but give no public health warning because its ‘still uncertain..no conclusive proof.. further research needed’

.. so no preventative action in homes, cars, nursing homes
hpsc.ie/a-z/respirator…
meanwhile high risk sectors have inconsistent, unsafe & out of date ‘rules of thumb’ & no warnings at all for homes, shops, cars & public transport

#Covid19 prevention: CO2 monitors used as proxy for inadequate #ventilation in #schools #nursinghomes etc, it’s cheap & effective way of preventing high-risk super-spread #Covid19Ireland #Level5 @NormaFoleyTD1 @DonnellyStephen @CMOIreland @paulreiddublin @ronan_glynn @CcoHse
High-risk #covid19 indoor air conditions are ~immediately~ preventable with public health advice about clean air, #ventilation & free/low cost solutions, it’s basic environmental science cires1.colorado.edu/jimenez/COVID/…
Autumn conditions in Ireland (10-15° & high relative humidity) are high-risk (yellow zone)
If #Covid19 surge is the weather, not bad behaviour, then policing, road blocks & fines won’t be effective at #Level5

[Thread] Clean air & Ireland’s inconsistent #Covid19 rules 1/

‘possibility of airborne transmission of SARS-CoV-2 through aerosols is still uncertain..no conclusive proof..further research needed’ HPSC, 22 Sept

^known very high risk & there’s evidence hpsc.ie/a-z/respirator…
..but ‘crowded indoor spaces have been shown to be associated with increased transmission.. determining what is due to proximity & poor hygiene practices, & what is ~due to poor ventilation~ though, is difficult’

^so, risk of spread due to poor ventilation is accepted by HPSC 2/
..but, no rules from HSPC, just ‘suggestions, specifically for commercial & public buildings’ ..& only for mech ventilation, which is small % of all buildings ..but ‘residential & healthcare settings fall outside the scope of HPSC document’ ..& very limited advice for schools 3/

#Covid19 High risk (yellow) zone at temperatures 5-11°C (spring & autumn)

An urgent public health message about clean indoor air & #ventilation (not fines & roadblocks) can have immediate impact on virus spread & prevent cases Image
WHO: ‘we are very concerned about rise in cases in Europe as it heads into winter’

‘Colder weather leads to behaviours that favour transmission of a respiratory virus- people tend to crowd indoors to stay warm, more often in poorly ventilated spaces’ smh.com.au/politics/feder…
‘overwhelming evidence that *inhalation* represents a major transmission route’

‘we urge public health officials to add clear guidance about importance of moving activities outdoors, improving indoor air & improving protection for high-risk workers’ science.sciencemag.org/content/early/…
