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:
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!!)
@ShellyMBoulder @D_Higuera_Ing 3/ @ShellyMBoulder lidero la publicacion de nuestro estudio sobre la superpropagacion de COVID-19 en el coro de EEUU, que demostraba la transmision por el aire
@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.
(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.
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!
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
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"
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."
