"With no vaccine to protect against #flu infection and no antibiotics to treat 2ndary bacterial infections that can be associated with influenza infections, control efforts worldwide were limited to NPIs ..." 1/
" ...isolation, quarantine, good personal hygiene, use of disinfectants, and limitations of public gatherings" That's very odd, there is no mention of the widespread use of #ventilation during the #SpanishFlu era
This is a curious omission since ...cdc.gov/flu/pandemic-r… 2/
....During & after the #Spanishflu , extraordinary efforts were made to design excellent ventilation in all public spaces including vaudeville halls 3/
...& people were reminded constantly to keep windows open in the home . So on a CDC page on NPIs for the #SpanishFlu , why is historical #ventilation efforts not even mentioned? We need to learn from the past to move forward into the future 6/

#bced Pro-D. The chair gave me time to explain what this thing was , humming in the middle of our circle of 27 mostly unmasked teachers. I said it was a #science project. We had #wildfires which gave us choking smoke....1/ #covid19bc#CorsiRosenthalBox
...It was built by the #science class. I shared that the #CorsiRosenthalBox can breath in >1000x more air than our lungs so any wildfire smoke, pollution or airborne diseases like flu, or covid is more likely to be caught here before we breathe it in! #bced After I presented 2/
after I presented, a teacher took a pic of it & asked me how to make it. I promised her a link to how to make a #CorsiRosenthalBox so she could make one with her child. Next, the humanities teacher borrowed the #science dept CO2 monitor , &the math teacher borrowed my monitor 3/

I had a chance to go to this @VSOrchestra Orpheum Theatre built after the Spanish Flu to be *pandemic proof* and WOW. This ventilating system is FULLY OPERATIONAL. Huge crowd 1/n
@VSOrchestra And under the seats there were these mushroom shaped objects...Fresh air from pipes provided a very gentle stream of air & note these air intakes were protected by the mushroom design. the stem emitted air, the umbrella part protected it 2/n
@VSOrchestra The air rose above the seats to the porous false ceiling above to vent all that air out! This was built in 1927 & it has better ventilation than most modern buildings #PandemicProof architecture 3/n
The @VSOrchestra Orpheum was built in 1927, shortly after the last worldwide pandemic ...."One of the most up-to-date ventilating systems on the continent was installed...Air was brought from the outside and blown through a series of water sprays or screens...1/2 #covid19bc
@VSOrchestra ..."heated to any desired degree, then forced through a system of ducts which distributed it to every part of the building hrough hundreds of small pipes which opened beneath the seats...2/n
@VSOrchestra ..."A complete change of air took place every three minutes, and with the aid of these huge air-washers, clean, dust-free air of even temperature was ensured at all times.” 3/n #orpheum#covid19bc
