1/ US Nurses, Unions, Allies Urge CDC to Acknowledge Covid-19 Aerosol Transmission to Help Bring Virus Under Control

aft.org/press-release/…

@rweingarten
2/ National Nurses United (NNU) and 44 allied unions and organizations, representing over 13 million members and their communities, are joining in coalition to urge the U.S. Centers for Disease Control and Prevention (CDC) to update its Covid-19 guidance to fully reflect the...
3/ latest scientific evidence regarding SARS-CoV-2 transmission through aerosols that infected people emit when they breathe, speak, cough, sneeze, or sing.
4/ “We have hundreds of thousands of members considered essential workers and risking their lives every day to support us all. They and their employers depend on accurate science from CDC. And the science clearly shows the danger of aerosol transmission"
5/ "For the past year, the CDC guidance on COVID-19 has been ignoring science and health experts."
6/ "The CDC's failure to update their guidelines has life and death consequences. Workers are going into confined spaces every day without sufficient control measures and employers are justifying it by saying they are following CDC guidelines."
7/ "It’s critical that the CDC recognize that COVID-19 can spread via infectious aerosols. For our members, the implications of the CDC not accepting aerosolized COVID-19 transmission poses grave risk as employers rely on the CDC’s guidance to implement appropriate mitigation...
8/ ... measures. We must follow the science and acknowledge how the virus spreads to adequately protect communities, particularly as the virus mutates and potentially more virulent strains spread"
9/ "The continuing workplace outbreaks among workers in such industries as, health care, retail, grocery, food processing, warehousing, among many others, points to the critical need for improved protections based on the latest science about airborne transmission. We urge...
10/ ... the CDC to follow the science, fully recognize aerosol transmission, and update their guidance now"
I couldn't agree more. Time for @cdcgov to update their guidance.

Y importante que se actualize también rápidamente en @CDCespanol, muchos de los trabajadores esenciales son hispanos y han muerto y sufrido desproporcionadamente en esta pandemia

1/ Aranet4 has created a very simple system to display the CO2 measurement in a large screen (smart TV) in public locations. This type of public display of CO2 should be required by law **in all public locations where we share air**. During the pandemic and later too.

2/ Because high CO2 and bad ventilation facilitate the transmission of respiratory diseases such as COVID-19, but also flu, colds (other coronaviruses, rhinovirus). And also e.g. measles, which is an issue again due to lower vaccination rates.

So this should be done permanently
3/ And also for reasons of health related to indoor air quality (air toxics, radon etc.).

@CDCgov: proper ventilation indoors can cut down the spread of COVID-19. But how can you tell if a space is well ventilated?

"One thing that's practical, with limited costs, and that is very useful, is to measure CO2"

1/ La principal fuente de contagio de la COVID es la transmisión por el aire ("por aerosoles")

Es hora de q los distintos gobiernos, así como organismos como la OMS, lo reconozcan y creen guías de sanidad pública que ayuden a la ciudadanía a protegerse mejor

#CovidEstaEnElAire
2/ Una medida muy fácil de aplicar y de explicar es el ajuste de la mascarilla. Tan importante como llevar una mascarilla de buena calidad.

En este video se ven fugas cuando las mascarillas (incluyendo FFP2 orejeras y quirúrgicas) están mal ajustadas.

#CovidEstaEnElAire
3/ Otra medida completamente factible es la ventilación. Abrir las ventanas es gratis, y en muchos sitios es suficiente abrirlas un poco, con el principio CDDM:

- Cruzada
- Continua
- Distribuida
- Medida

Una buena iniciativa de @elcorteingles. Pero no muy bien ejecutada. Esos niveles de CO2 no se han visto ni al aire libre desde 1960!

Ahora al aire libre hay 415 ppm, y en interiores siempre más.

Por favor arreglen estos medidores.
Para ver el registro de CO2 al aire libre (remoto) va. ajo, ver e.g.:

e360.yale.edu/features/how-t…
Imagino que es un error inocente por ser novatos en esto del #covidCO2. Pero importante que lo arreglen deprisa y verifiquen regularmente que funcionan bien. Si no en vez de dar confianza, la quita. E.g. comparando con un medidor portátil calibrado al aire libre como el Aranet4

1/ Seis meses despues de mi Tribuna en el @el_pais (a la vez en inglés en @TIME magazine), es de locos que todavía tengamos que luchar por esto

Es obvio que la COVID se transmite por el aire. Pero la OMS @WHO, @sanidadgob, etc. siguen sin explicarlo claramente, gente confundida
2/ Se sigue desperdiciando gran cantidad de dinero en desinfectar.

Se me cayó el alma a los pies hablando con un Dpto. de educación de gran ciudad. Habían gastado una fortuna en limpiadores y desinfectantes. CERO en ventilación, medir CO2 etc.
3/ Dpt. Educ: "Mucha desinfección para hacer que los padres se sientan seguros llevando a sus hijos a la escuela."

Realidad: teatro de higiene, dando a los padres una FALSA sensación de seguridad, mientras exponen a las familias al contagio de COVID, sin tomar medidas reales.

Six months after my Op-Ed in @TIME Magazine, it is shocking that the are still having to continue to fight this battle.

It is now obvious that #COVIDisAirborne, but @WHO, @CDCgov, & many health ministries continue to drag their feet. Don't say it clearly, ppl not well protected
2/ Many governments continue to waste large amounts of money and time in surface disinfection.

I was really saddened when talking to the Education Dept. of a very large city (in South America, about to start academic year). They had spent a fortune on cleaners and disinfectants.
3/ This city that had spent a fortune on disinfectants, had spent ZERO on ventilation, CO2 monitors, better masks etc.

They were disoriented when I asked them about it. @WHO has done a terrible job, obfuscating and disinforming about transmission.
