Simple truths... Suppression of Bias will always be helpful in determining Truth. Suppression of Airborne particles will always be helpful with Covid.

@COVIDSciOntario

COVIDScienceOntario try and "Quote Tweet"
"this" particular tweet This. Is. Different. 1/7. Yes, we’ve been at this for a year; we’re exhausted; “we’ve heard it all before”…. Today, our news is different. The situation is more serious. We also have options. Pls read these 7 tweets & share. #COVID19Ontario covid19-sciencetable.ca/sciencebrief/c…

Trying to understand CO2 as a control.

I understand this is a simplification. Q1

If: (background CO2) = (x)ppm "15 Students 1 Teacher"

If: control for infection risk is = +750ppm CO2

Room after 3 hours use =
CO2 meter reading rises to (x)+750 ppm

It is at this point:
CO2 meter reading =>"equal to or greater than"
(x)+750ppm that it becomes unsafe.

Catchphrase:

HEPA plus Ventilation "IS" the Facemask of the Classroom!

"Everyone needs to find a way to understand this" This is a simplified version obviously:

*=Relative Effect of

"(Volume of Area)+(*Masks)+(*HEPA)+(*Ventilation)+(*Distancing)=(Room Time)"

(Distancing=(calculation of *Masks+*HEPA+*Ventilation)

Would it be possible for a theoretical mathematician an expert in aerosole transmission and or ventillation to collaberate on the realtime effects of varying degrees of Ventilation vs Space Vs Children within a good safety margin in respect to classroom sizes and no. of students. Some other parameters:
Air Changes and co2 monitoring.
Standard room sizes and cohort pupil sizes.
Volume of air in room (not all ceiling heights same.)
Movement to from classrooms. Length of lessons. etc.

The current

"GOLD STANDARD" for Schools and Education !

America leads by example.

Operational Strategy for K-12 Schools through Phased Mitigation

cdc.gov/coronavirus/20… 1. Consistent implementation of layered mitigation strategies to reduce transmission of SARS-CoV2 in schools
2. Indicators of community transmission to reflect level of community risk
3. Phased mitigation and learning modes based on levels of community transmission

A glimmer of hope:

FINALLY FULL RECOGNITION !!!
#COVIDisAirborne

Fiona Bruce:
"I`m a Doctor in Melbourne vaccinations alone are not going to be enough"

"we need input from occupational hygienists, aerosol experts and ventilation engineers"
