As contagious as chicken pox.
Far fewer pediatric beds - provide specialized care.
27k pediatric beds
5400 PICU
In the US
Usually 80% full

Asymptomatic spread is an issue!
Aerosols that float and can fill a room. Like infectious cigarette smoke.
Some droplets, droplets drop, aerosols float.
Aerosols drive disease.

Need to clean where the virus is.
#DeltaSchoolsAirborne
It's very contagious - 1000x the viral load.
If you believe 15 minutes from original COVID you could inhale the same amount of virus in one second.
BUT we can clean the air.

Indoors far higher risk that outdoors.
Not wearing masks is a bad idea.
If you have to be indoors without masks, no talking. Worse exerting, singing, talking loudly.
Not just in the classroom. The person that's infectious doesn't have to be in the same room as you. Aerosols

Linsey Marr #DeltaSchoolsAirborne masks for kids!
Not sieves.
Use filtration!
They do work - it's physics.

Delta requires better masks!
Comfort
Fit
Filtration
Double masking does help - surgical mask under a tight fitting cloth masks.
N95s don't fit well for kids.
KN95 and KN94 some are made in children's sizes.
Cloth masks that include high filtration if they fit well!

Dr. Corsi - effective measures by fall?
Some yes, some no.
Children spend about 20% of their time in school - more than anywhere other than home.
Indoor air quality is important

Even before the pandemic air quality in schools not good.
Goal should be reducing risk by reducing inhaled dose.
- Time
- Breathing rate
- Concentration of particles in air
Reduce that last thing -
- Masks
- Increase ventilation
- Increase filtration

Outdoors helps (but isn't magic)
Filtration - clean air delivery rate
People did drag their feet on some of these systemic changes in buildings
Can still be done
Portable HEPA - with a formula to calculate it - see video
Approximately 33 minutes in

All of this could be done for far less money than what people think.

We need to be going in to check ventilation when there's an outbreak. We need to measure air.

Using C02 as a ventilation clue from @Poppendieck
Can use it to figure out how much of others people exhalations we are breathing in.
Yuck.

Measurements need to be done throughout the day!
Most classes are not at the level they need to be at. Pre-pandemic!
But low C02 levels do not mean it's safe.
It's just one layer.

How many air changes for Delta? Is a question I have!

Prioritize the air cleaners to classrooms with less existing filtration.

MERV-13 is recommended.
More are available this year
Low relative cost
Schools should be spending their money on these
Costs can be covered under American Rescue Plan

Vaccines, vaccines, vaccines, vacccciiiiiines. Dr. Schooley (great name for this presentation)
Two goals for vaccines!
Plus vaccines lower viral loads.
Less viral load, less COVID in the air as it is exhaled.

Schools need to be transparent!
Kids like to watch the C02 monitor.
Work with the public.
Don't turn your air filters down due to noise.

Masks: get the smoke at the source with masks.
Less pressure on other layers of protection with that.
Doctor mask exemptions? Get a doctor's note but then they worked with the school team - until that process occurred no exemption. Confirm!

"Eating lunch indoors in school is similar to having a pool full of children who hold their bladders all morning then put them all in a hot tub and let them relieve themselves all at once."
Not sure if I got that @HuffmanLabDU quote exact but what a wonderful analogy!
