In Ireland half of the people who died from #Covid19 were infected in fewer than 400 buildings
Ireland has >2,500,000 buildings
Risk is about buildings, not behaviour
Spread is about clusters, not contacts
Control is about eliminating the hot spots (pic: @mdc_martinus )

this blew up, so a🧵of info
#1 almost all #COVID19 transmission is due to infected air trapped indoors/in vehicles
#2 the air conditions are known, measurable & preventable
#3 managing the air & the people can make ALL buildings low risk
CLEAN AIR can (& has) stopped pandemic

..some history
Indoor air quality/ventilation in buildings has been regulated since at least 1631 (390 years!) for public health & disease control
Florence Nightingale used ventilation to stop infection
Chicago used ventilation to suppress Spanish Flu pandemic in *6 weeks*

..some clues
Here are 50 #covid19 super-spread events (Feb-Dec 2020) pre-Delta
Super-spread events are investigated... but super-spread conditions (trapped infected air) can happen anywhere, even in empty rooms
Airing rooms prevents risk of infection

.. so why aren’t we doing this already?
Many Western & English-speaking countries are following advice of @who (“wash your hands”).. but not in Asia, where #Covid19 has been controlled more effectively with airborne precautions
