Last yr, I called a manufacturer of school CO2 monitors to ask how hard it'd be for schools/ @CADeptEd to show classroom CO2 levels on a public website. There are robust APIs, so it'd be easy. Why don't we have a public CO2 dashboard for all schools that got CalSHAPE $?🧵⏬ Many California schools have connected CO2 monitors installed through CalSHAPE. Is school CO2 already aggregated somewhere by @CalEnergy, @ChairHochschild @Patty_CEC? If so, does @CAPublicHealth @AirResources @CADeptEd @CAgovernor have access to the data /could they get it?🧵⏬

Last week, I sent a letter to @CAPublicHealth expressing concerns & asking❓s about CA's reduction in isolation to 24 hrs for asymptomatic cases (see 🧵below). Yesterday, I got an unexpected (but welcomed) call from a senior official at CDPH

I wish I could tell you the call was reassuring. It wasn't. While I appreciated the call, I was left with the impression that pushing "urgency of normal" is more important than preventing the spread of COVID & other pathogens & protecting long term health 🧵⏩

Please RT & share this important science & ?s 🧵on @CAPublicHealth's new SARS2 isolation guidance w/ @GavinNewsom @CAgovernor @CHHSdatanews @CA_DIR @OSHA_DOL @USDOL @RepDeSaulnier @POTUS @SecBecerra @CDCDirector @HouseDemocrats @HouseGOP @SenateDems @SenateGOP & your reps. 🧵⏩ ~60% of people catch SARS2 from someone asymptomatic. Instead of encouraging increased vigilance, testing & staying home when positive, on 1/9 @CAPublicHealth ⏬ its SARS2 isolation guidance to 24hrs for asymptomatic but + people, asking them to 😷 🧵⏩

On Jan 16, I phoned @CAPublicHealth & asked to speak with someone about the "COVID-19 Disease Control & Prevention Memo" &  "COVID-19 Isolation Guidance" of Jan 9. The rep asked me to email my questions & concerns & promised to escalate them to the ID team, which I did. /1 I followed-up on Jan 17 to make sure @CAPublicHealth got my email & forwarded it as promised. They did & I was promised a timely reply. 4 days later, I've not heard back, so I guessed Dr. Tomas Aragon's (head of CDPH) address & emailed him this am. /2

What is your justification for sending covid positive kids into school while contagious, @CAPublicHealth @OUSDNews? This runs against @cdc & @who isolation guidance. What are you doing?! @GavinNewsom @SecBecerra @Cal_HHS @CDCDirector @POTUS @CAgovernor /1kron4.com/news/bay-area/… Just last week in an interview with @ChrisCuomo, @realDrBirx said pointed out the mistake of ignoring asymptomatic spread, and yet this is exactly what @CAPublicHealth's new policy of requiring just 24 hours of asymptomatic isolation does. /2

This is a next gen DIY air filter I built for #California #wildfire season, leveraging a design from @AbraarKaran & @sri_srikrishna. I used foam core instead of cardboard for the shroud, which makes it look pretty. Big size improvement on #CorsiRosenthalBox & air smells great! /1 Here's the side view. I sliced a 7" circle in the center of 30" foam core (@DollarTree via @Instacart) & duct taped a 16" pizza screen (@Walmart) inside to protect toddler fingers. I sliced a straight cut half way through the foam core at 4.5" from each side w/ an Xacto knife. /2
