1/ TRANMISIÓN DE VIRUS RESPIRATORIOS POR EL AIRE: DIVULGACIÓN CON COMICS

Nuestro artículo reciente en @ScienceMagazine, presentado de forma comprensible a través de comics.

Artículo: science.org/doi/10.1126/sc…

Comics creados por @ChiaWang8, y traducidos al español por @nanoprofe
2/ El elenco de actores: las gotículas (grandes, caen rápidamente al suelo) y los aerosoles (pequeños, flotan en al aire como el humo)
3/ ¿Qué son los aerosoles?
4/ ¿Cómo se dispersa un virus en la transmisión por aerosoles?
5/ ¿Cual es la principal diferencia entre aerosoles y gotículas?
6/ ¿Cuánto tiempo permanecen los aerosoles en el aire?
7/ Los aerosoles con virus (= "virosoles") son afectados por los flujos de aire y la ventilación
8/ Los virosoles luchan contra el reloj!
9/ Los aerosoles pueden ser filtrados de forma efectiva por limpiadores de aire portátiles (HEPA, o más baratos con un ventilador y un filtro, ver bit.ly/FAQ-A):
10/ La luz solar y las lámparas de ultravioleta inactivan al virus al dañar su material genético.

[Pero mejor ventilar, y si es necesario, filtrar, y solo usar lámparas UV en situaciones más difíciles]
11/ Los aerosoles pueden entrar y depositarse en la región bronquial y alveolar de los pulmones

[Aunque también se depositan en la nariz, traquea etc.]
12/ ACE2 es el receptor celular de entrada que enlaza con el SARS-CoV-2, y le ayuda a invadir las células
13/ Las aglomeraciones con un factor clave en los eventos de supercontagio
14/ Las mascarillas reducen el contagio. Pero ¿por qué hay gente que se infecta a pesar de usar mascarilla?
15/ La desinfección de superficies NO detiene la transmisión del virus por el aire

[Y es un desperdicio de tiempo y dinero en casi todas las situaciones. Pero hay que seguir lavándose las manos]
16/ Las barreras físicas (mamparas) pueden atrapar mayores concentraciones de aerosoles, y AUMENTAR los contagios

[Sólo son útiles en situación de "cajero", pero no laterales en oficinas o escuelas, donde aumentan los contagios: dx.doi.org/10.1126/scienc…]
17/ ¿Cómo detener la transmisión aérea?

Hacen falta una serie de capas de protección, pero muchas medidas son gratis o de bajo costo. El aire libre es de las más eficaces.
18/ Estos comics se pueden reproducir (sin necesidad de permiso] para fines educativos, con referencia al artículo de Science.

[No se pueden reproducir sin permiso para fines comerciales]

1/ Survey of CO2 indoors during trip

CO2 (above ~400 ppm outdoors) indicates the amount of exhaled air (& virus) trapped in a space

Also per recent scientific results by @ukhadds, CO2 helps SARS-CoV stay infectious in air much longer

@united flight boarding, pretty terrible! Image
2/ This is the trip so far:

-Low outdoors
-Pretty high ~2000 in @RideRTD bus to airport
- ok ~800 at @DENAirport, except restroom ~1500. Not sure why restrooms at this airport are so often poorly ventilated
- Then boarding on @united, ventilation OFF, so huge increase till ON Image
3/ For details of the recent results on how and why CO2 makes SARS-CoV-2 stay infectious much longer in the air, see this recent thread by @ukhadds

1/ "After four years of fighting about it, @WHO has finally proclaimed that viruses, including the SARS-CoV-2 virus that causes COVID, can be spread through the air"



By @maggiemfoxscientificamerican.com/article/a-figh…
2/ "It took four years to get here because some leaders in public health, medicine and science clung too tightly to precision and semantics"

"One particular moment of shame came on March 28, 2020, when WHO tweeted: “FACT: #COVID19 is NOT airborne.”

3/ "Words matter. When people heard that COVID might spread on surfaces, they wasted time wiping down groceries. People who misunderstood airborne spread needlessly wore masks on outdoor walks and veered off sidewalks to avoid their neighbors."

1/ @WHO has published a report on updated terminology for disease transmission

I've seen some debate about it. My take:

- Terminology itself is ok. Big progress
- But no recommendations of how to protect!

Report:

Press release: who.int/publications/m…
who.int/news/item/18-0…
2/ The report was likely the result of intense pressure on @WHO during the pandemic:

- They denied that #COVIDIsAirborne on March 2020
- They finally accepted it 2 years later

nature.com/articles/d4158…
@WHO 3/ To their credit, @WHO did invite some of their critics to be part of the committee.

What was the terminology before. In medical circles:

- droplet transmission: if it happened in close proximity, or if particles were > 5 microns

- airborne transmission: if it happened far

1/ New paper in @ScienceMagazine: "Mandating Indoor Air Quality for Public Buildings"

Explaining current status of indoor air quality standards (in short: bad or non-existent), the huge health benefits that would arise from them & proposing a path forward
science.org/doi/10.1126/sc…
Image
2/ "People living in urban & industrialized societies, which are expanding globally, spend more than 90% of time indoors, breathing indoor air (IA)."

"Most countries do NOT have legislated indoor air quality (IAQ) performance standards for public spaces"

science.org/doi/10.1126/sc…
3/ "Few building codes address operation, maintenance, and retrofitting, and most do NOT focus on airborne disease transmission."

"We propose that Indoor Air Quality (IAQ) standards be mandatory for public spaces"

1/ Checking the ventilation by measuring CO2 as I travel to the #AAAR2023 conference

@RideRTD bus to Denver airport. Bus route had started 3 min before I got in, already 1500 ppm

Typical of these @RideRTD buses, poor ventilation Image
2/ Not getting any better as time passes in the @rideRTD bus to the airport...

7% of the air is being re-breathed, it has already been in someone else lungs when each of us breathe it. Image
@RideRTD 3/ Given the often poor-to-mediocre ventilation in US transportation systems, I wear N95 masks (not KN95, less good)

In this case @3M VFlex, which I tested at 99.99% filtration for myself

It also stays sealed when I talk, doesn't distort my speech (& add to my Spanish accent) Image
