PRESS RELEASE: We Support APS Keeping Masks for All, in Defiance of the Governor’s Anti-Science Proclamation

We support Superintendent Duran, and the Arlington County School Board, in announcing that under their constitutionally invested authority they will continue to mandate universal masking in our schools. This is an effective health measure that ensures all children have access to in-person education, and in a recent survey of more than 70 studies,...

In the News! Outdoor Lunch Petition Launched

Indoor dining during the pandemic is widely recognized as a high risk activity. The CDC, Dr. Fauci, epidemiologists, experts and the Arlington School Health Advisory Board all recommend that schools hold meals outdoors. Yet, APS has only "encouraged," but not required, outdoor dining in its schools, leaving this critical safety measure to the...

Picking this thread back up! Digging into aerosol tau (whatever the fuck that means..)

Actually aerosol tau is a really HANDY number. It tells us how long it takes (in seconds, mins, or hours) for particles (suspended in the air) to leave a room.

Prior to COVID, my work was on maternal mortality. About 700 birthing people die each year. The federal gov dedicated $100 mill to address this. We have a campaign- chasing zero, with a goal of eliminating maternal death.
When I hear "only 800 kids have died of COVID" or

Here's a great visual of how air cleaners - in this case Corsi/Rosenthal boxes - pull aerosols out of the air.

Once they are on filter they are no longer a threat. 2 decent filers in a classroom should do this every 10-12 minutes. 2 is better than 1 as you have lower noise. ...

A lot in this post by @NCLoralie: CFD air modeling in a classroom to visualize how well a #CorsiRosenthalBox or HEPA air filter cleans. Worth watching the short video at a min. Aerosols that hit filter, no longer an airborne risk.

It's a start.

UPDATE 2: Police have charged Amelia King with making a terroristic threat on school property. She’s been arrested and released on $5000 bond.

This is a good start to accountability. No one should be allowed to get away with such horrific calls to violence.

Covid is looking a little better on Friday nights in the ER #arlingtonva

More than 6000 children were hospitalized with COVID in the US in the past week.

Mask policies, free masks and tests, and equitable vaccine delivery could have reduced the spread.

Now is the time to prepare to implement these during the next surge.

On this, the 73rd day of #ecmo support for Covid, this young #pedsicu patient was decannulated. The work it took by the team & by him to survive these 73 days was inspirational & emotional. We’re so proud of him. His journey below in🧵 Shared w/ permission from his devoted mom 💪🏻

Back to in-person teaching at @UofDenver this week. Omicron still surging, but masks + vax mandatory & frequent, negative PCR test for building access.

I built a new #CorsiRosenthalBox, brought a box of new N95s, & see that #CO2 is consistently <750 ppm for my class. #DUYourPart

Not sure how much tolerance it’s possible to have for the “I expect the pandemic to be over but am unwilling to wear a mask” point of view.

Omicron will not be the last variant nor will SARS-CoV-2 be the last novel pandemic pathogen. The debate shouldn’t be whether xyz is endemic or not but rather about what investments we must mobilize now to build strong public health systems for both immediate & long-term benefit.

If you signed the petition supporting keeping the mask mandate while omicron rages, make sure to send a nice note to your local superintendent and school board member. Otherwise they’re just hearing from the loud minority of anti maskers. 👍

Thrilled to share the #FreshAirClip to detect a person’s exposure to #SARSCoV2 in the air. The small clip can be worn or placed in a room to monitor exposure to droplets or aerosol containing virus. #COVIDisAirborne #NSFfunded
