1H/ The new #COVIDHallofHumor

As many of your know we have started 2 ongoing threads of good and bad practices worldwide against COVID transmission

- #COVIDHallofShame:

- #COVIDBestPractices:
2H/ The good examples are much more fun to compile, but unfortunately there seem to be many more bad examples everywhere.

So inspired by tweet by @microlabdoc, I thought it may be good (at least for our mental health) to start a #COVIDHallofHumor

Pls submit by adding that tag
3H/ UK 🇬🇧: Here we see @microlabdoc demonstrating a new method to clean the air of viruses

Cheap and easy. Only need pins, a scarf, disinfectant wipes, and work that you really want to avoid for the next 30 min!



#COVIDHallofHumor
4H/ CANADA🇨🇦: in response to the news on the image below from TODAY about more investment in disinfection for COVID-19 (news.ontario.ca/en/release/100…), @DadEducator had a great response:



#COVIDHallofHumor
5H/ SPAIN🇪🇸: upon news about useless transparent fishnet masks (pic on the left), @eljoserc quipped that those are just as good as needlepoint preservatives, provided they have an official certificate (as the masks do have, somehow!!)



#COVIDHallofHumor
6H/ MEXICO🇲🇽: difficult as it may be to believe, this is a real video published by Mexican Gov. @GobiernoMX a few days ago about COVID-19 prevention

So bad it is humorous

- Virus infects outdoors
- COVID Prevention is to eat healthy foods and avoid junk food

#COVIDHallofHumor
7H/ PHILIPPINES🇵🇭: A prominent lawyer taping the mask to the inside of his face shield



#COVIDHallofHumor
8H/ USA🇺🇸(San Francisco): great Halloween decoration for a house

[though now the house needs to upgrade from surgical to N95😉]

1/ Las enfermedades pueden propagarse entre viviendas a través de los sistemas de ventilación compartidos EN ESPANA, según un estudio estadounidense

La nvestigacion analizó un brote de COVID-19 ocurrido en un edificio residencial de Santander al empezar la pandemia
2/ El articulo de la vanguardia q lo cuenta:

1) Something very clear from this Hantavirus outbreak is that @WHO is still quite confused about airborne transmission

Still confuse "close contact" (a setting) with a mechanism of transmission

Do not understand that ease of transmission in close proximity ==> likely airborne
2) Several colleagues have published this note in @bmj_latest summarizing this problem with @WHO:

bmj.com/content/393/bm…
@bmj_latest @WHO 3) I spent a couple of years of my life trying to make progress on this issue. This is how me and many colleagues felt during the pandemic.

Frustrating that @WHO is still very confused

(1) Veo el lio que se ha montado con el hantavirus en el crucero y queria decir algunas cosas. La mas importante:

**Esto NO va a ser una pandemia**

Estoy de acuerdo con @mvankerkhove e incluso con Fernando Simon. Y nadie me puede acusar de estar siempre de acuerdo con ellos
(2) ¿Por que no vamos a tener una pandemia de hantavirus?

Porque es un virus q se conoce. La variante de los andes se puede transmitir de persona a persona. Casi seguro q se transmite por el aire, por aerosoles.

Pero con dificultad. NO es un virus muy contagioso.
(3) El hantavirus es menos contagioso que la tuberculosis pulmonar, que la causa una bacteria por transmision por el aire exclusivamente. Y que anda suelta por ahi, pero no causa una pandemia rapida como el SARS-CoV-2.

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
