Excellent new guide on healthy #school buildings. Should be mandatory reading & discussion by all #K12 school boards, districts, school leadership.

Short, easily readable, w/ practical recommendations & support - for COVID & well beyond.

2/ Summarized interventions for airborne infectious disease prevention:
1⃣ Commission buildings and examine existing systems
2⃣ Ventilate with clean outdoor air
3⃣ Improve the building’s air cleaning efficiency through evidence-based air cleaning treatment such as filtration
3/ Interventions, cont'd:
4⃣ If the ability to upgrade ventilation and air cleaning is limited, use portable air cleaners with high efficiency particulate air (HEPA) filtration
5⃣ Consider other evidence-based air cleaning approaches in the context of existing strategies
4/ "Health co-benefits go beyond disease transmission"

Improving indoor air quality of schools is SO much more than just prevention of disease! Opportunity is now for long-term value.

⬇️ Less asthma
⬇️ Less missed school days
⬇️ Fewer respiratory symptoms
⬆️ Higher test scores
5/ Fabulous job on the report by another all-star team:
@CorsIAQ, @ShellyMBoulder, @MarissaVanry, @linseymarr, Leslie Cadet, @NiraPollock, @drdavidmichaels, Emily Jones, @meiralevinson, Yuguo Li, Lidia Morawska, @j_g_allen

6/ A similar take on needing to make #K12 schools safer wrt COVID and all indoor air quality issues (and for all other schools & workplaces) -- see also the recent Op-Ed that @ChemDelphine, @marinavance, and I wrote.
coloradosun.com/2021/04/23/saf…
7/ Also see this open letter by @marwa_zaatari & @MarcelHarmon1 (supported by 12 other #IAQ experts) focusing especially on the use of electronic air cleaning equipment in buildings (i.e. use evidence-based strategies instead).
medium.com/open-letter-to…
8/ One goal for our Op-Ed on healthy air in schools was to motivate grass-roots advocacy by constituents.

Read @TheLancet #school report & then engage w/ your district to make sure they take it seriously.

"We urgently need safer air in schools"

Last month Profs. @ChemDelphine at CU, @marinavance at CSU, & I wrote an #OpEd published today by @ColoradoSun. We wanted to bring a team of #Colorado experts to call for action & advocacy wrt #K12 schools. (1/x)
coloradosun.com/2021/04/23/saf…
2/ "We encourage school districts to use stimulus funds to improve the indoor air quality of their schools. Use evidence-based strategies. Avoid technologies that have not been proven by peer-reviewed scientific research."
3/ "We encourage students, teachers, and the community to engage with district administrators and encourage them to leverage funds to support both the immediate and long-term health of students and staff."

I respectfully disagree that the recent (& important) editorial/review in @TheLancet "omits or dismisses crucial observations." A statement that "close contact" spread cannot be driven largely via aerosol inhalation is a mischaracterization of the inhalation route. (1/x)
2/ You can be infected by a respiratory virus by:

(1) touching something/someone infected & transferring to yourself
(2) receiving a direct spray of large droplets that hit e.g. mucous membranes
(3) inhaling virus in aerosols at either close or long range
onlinelibrary.wiley.com/doi/10.1111/in…
3/ All three pathways can happen at close-range. Direct observational evidence for any one of the three is nearly impossible for individual cases.

Article outlines clear reasoning why aerosol inhalation should be treated as an important (not only) driver.

This dude is just wild. If he weren't so influential, best just to ignore his theories about the mysterious, undiscovered properties of air to kill viruses.

Interesting interview by @EJBourke, w/ sanity checks by Drs. Morawska, @jljcolorado, @drajm. (1/x)
abc.net.au/radio/programs…
2/ What gets me is that by invoking the idea of an undiscovered force in outdoor air that is killing airborne viruses, he is somehow trying to change the narrative & ignore his constant opposition to airborne transmission and that EVERYONE agrees that outdoor air is safer.
3/ Enclosed indoor spaces trap exhaled aerosols from diluting into bigger outdoor spaces. Bringing magical anti-virus outdoor air inside is NOT the point. Pushing viral aerosol out IS the point.

This basic principle has been daily news coverage for months.theatlantic.com/health/archive…

Ten scientific reasons in support of airborne transmission of SARS-CoV-2

By all-stars: @trishgreenhalgh @jljcolorado @kprather88 @zeynep @DFisman & Robert Schooley 👏 (Summary below; 1/x)
thelancet.com/journals/lance…
#1 "superspreading events account for substantial SARS-CoV-2 transmission"

#2 "long-range transmission of SARS-CoV-2 between people in adjacent rooms but never in each other's presence has been documented in quarantine hotels."
#3: "asymptomatic or presymptomatic transmission of SARS-CoV-2 from people who are not coughing or sneezing is likely to account for at least a third, and perhaps up to 59%, of all transmission globally and is a key way SARS-CoV-2 has spread around the world"

Stronger prevention against the aerosol component of COVID spread is absolutely crucial for public health, especially healthcare. Major pushback against this has cost many lives. Please listen (2 min) to the best reasons why this WHO leader says they are not worth it. 1/
2/ In relation to the comments by Dr. Conly about N95 risks to pregnant women - this is a nice thread by @caruzycki showing major errors in how that study was designed. Authors modified an N95 mask until it was very to breathe through first.
3/ In contrast, there are lots of legitimate & very important reasons to use upgraded masks (N95s, elastomeric respirators) - because they protect lives.

A really nice story from Kim Tingley about the Skagit Valley chorale outbreak from last year.

Walks through the personal side of the tragedy, how the outbreak provided crucial clues about the airborne spread of COVID. [+ choir song link] HT @jljcolorado
nytimes.com/interactive/20…
2/ “'We proved how you get this thing,' Comstock told me. 'And it’s so damn frustrating to watch the news and see that they’re ignoring it.'”

Link to the important paper by @ShellyMBoulder @jljcolorado @linseymarr @CathNoakes et al.:
onlinelibrary.wiley.com/doi/10.1111/in…
3/ "But the notion that [sitting close, sharing snacks, stacking chairs] caused so many infections, as @jljcolorado characterized it to me, is 'absurd.' He says that that emphasis helped enable the W.H.O. and the C.D.C. to maintain and defend their guidelines."
