2/ Here's the breakdown of COVID-19 exposures and positive cases by school community as of the start of the week.
3/ The trend on youth cases in Arlington... via VDH data.
4/ Looking at cases by school by week... The first is all events (exposures and positives); the second is just positive and likely COVID-19 cases. Disturbing trend in transportation (4 cases), given that so many bus drivers have died according to @LostToCovid.
5/ New data being released by APS showing density of occupancy in school buildings and breakdowns by race on benefits of being inside a school building.
6/ As older people in @ArlingtonVA are getting vaccinated (Good work @Matt4Arlington!) and more kids are indoors together in schools, more kids cases are showing up as a higher percentage of overall cases, mirroring the national trend that COVID-19 is becoming a young person's 🦠
7/ After kids returned to a lower occupancy hybrid model, our *detected* COVID-19 cases in Arlington leveled off at a higher rate than mid-fall/early winter so far.
8/ VDH data shows that kids cases are increasing, FYI @GovernorVA. This is what we expected with putting this age group back inside without better, detailed, evidence-based guidance on the settings in school where the virus can breakthrough and continue to jump to new hosts.
9/ Updated list of our Northern Virginia school outbreaks. @GeneralsPride and another APS school that hasn't been revealed will soon be joining @YorktownHS here with confirmed school outbreaks. New investigations are in red. More outbreaks now than last fall.
10/ More data on kids and cases in Arlington...
11/ APS data totally omits some cases that ARE in this age bracket in town. Do the schools not know about these? Is the APS data list missing some cases? (We think that's probable.)
Remember, just added a thread today that shows how known cases are big undercount, for 0-19 age.
12/ A note on APS data — it changes CONSTANTLY. @APSReady says they're deleting duplicate cases.
For instance, @WMS_WolfPack deleted 11 cases, many of them staff +, in the past week. @APS_ATS has deleted 17 cases.
Our list is a snapshot of what was online when we made it.
13/ Data on rising COVID-19 cases in children is being tracked by the American Academy of Pediatrics. April is breaking records for cases in kids, and now we have 3.6-million children who have had this disease (confirmed by tests) in USA.
Sharp opinion by two pediatricians on why mitigation matters, esp. for the next year: usatoday.com/story/opinion/…
Michigan has had a good bit of coverage because when you have a lot of spread... kcra.com/article/increa…
16/ Sharp breakdowns by race/ethnicity are very apparent in the APS data released in the past week about choices on mode of schooling this spring. Kudos to @SuptDuran for wanting things to be more transparent, posting info like this online:
P.1 is spreading in VA, confirmed, but not listed here yet. VA's numbers in screenshot, steady growth of VOCs, estimated 45% of VA cases.
18/ That's the data roundup this week. We're heading outside and taking a few days' Twitter break. Stay safe, mask up, schedule your vaccine, and choose a True HEPA air cleaner over other air cleaning technologies. We could reduce 95% risk indoors, but take shared meals outside.
1/ ASHRAE (professional engineering org for HVAC professionals) has a technical committee on the design of educational facilities that has released new guidance on how schools can achieve “advanced indoor air quality.” @SuptDuran@jmayo443@APSFacilities
2/ The complete report can be found here, but a 🧵 to sum up some of the ideas. APS falls very short on most of this, but its our hope that new buildings will be built with some basis of best practice and health — optimal conditions for learning. ashrae.org/file%20library…
3/ First, verify, test, and balance HVAC systems, including direct measurements from at least 10% of classrooms, at a minimum.
MINIMAL testing should include CO2 levels are being maintained at <750 ppm over outdoor air. Also levels for PM2.5 and toxic volatile organic compounds.
Covid can cause damage to the heart on a cellular level that can lead to lasting problems, including irregular heartbeats & heart failure, new research suggests.
And the plan is? 5-10 infections for every kid in their school years? Brilliant, @SuptDuran.
Today, APS has 9,862 cases of COVID on dashboard, @SuptDuran. We counted at least 115 cases pre-dashboard. Looks like +23 more and APS hits the 10,000 mark. Massive waves happened when masks came off. APS lacks impactful air cleaning to prevent damage to health of kids/staff.
Saying you did something, and checking a box, is not the same thing as actually doing it well, @SuptDuran. Times have changed. Masks are off a lot of kids. You need more clean air. Take off the blindfold and do something about it.
1/ Finally got the full pandemic data file via a FOIA request from #Arlington Public Schools. What follows is a historic account of how the pandemic went in the smallest "self-governing" county in the USA; also one of the wealthiest (7th) and most densely populated (12th).
2/ COVID continues to be a significant, systemic challenge that impacts schools, teachers, kids and their families — as well as education. Data can inform policies to implement for the long run to disrupt COVID & other airborne illnesses.
3/ Data that follows is from APS. Notes: APS stats lack cases from fall 2020, before the Qualtrics system (+100 cases?) Also, APS continuously updates/deletes double records. (Likely +/- 20 records out of more than 9,000 cases in our file.)
@sri_srikrishna@RanuDhillon@AbraarKaran We’re re-running our spreadsheet of all classrooms in Arlington, where staff accepted 4 ACH and we had 7,000+ cases of COVID. They remind everyone how Dr. Allen blessed their 4 ACH when we ask for better. Nothing has been more detrimental to our efforts to get more clean air.
@sri_srikrishna@RanuDhillon@AbraarKaran We do want to see how many classrooms have 10 L/s/person of clean air, based on last year’s enrollment, and what the size of the gap is, if measured that way, especially with more crowded schools. The Italian study suggested up to 14 L/s/person.
@sri_srikrishna@RanuDhillon@AbraarKaran Sadly, these are numbers on paper. Systems ARE NOT functioning like building plans promised as long ago as 2002!!! We don’t don’t really trust these numbers. There’s no budget to measure or track real world performance. Now we have ionizers in rooms, generating who knows what.
1/ Falls Church has the least amount of poverty of all VA localities. Wealthier suburban families with access to healthcare are weathering #COVID19 better than others. From a glance, #SOL slump seems to have struck hard at poorest counties with highest per capita rates of COVID.
2/ We would like to see this state invest a lot more in correcting decades of deferred maintenance that make our schools an ideal setting to spread COVID-19 (and a less than ideal setting for learning and health). Our schools facilities should be a lot more pandemic resilient.
3/ The pandemic is THE problem. More kids miss more days of school in districts with less health protections. More sickness and and cognitive impairment is not good. Youngkin ordered schools to let #COVID rip in spring, now blames schools for damage HE CAUSED through SOL season.
1/ A CDC reorganization will not fix this, if the CDC does not base its guidance on science.
CDC failed early to communicate #COVIDIsAirborne and discouraged mask use — to date the most effective & cheap strategy. (Different from other countries w/better response.)
