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.
📌 Lots of asymptomatic COVID-19; testing caught cases MUCH higher than typical school reporting (self-reports and symptomatic).
📌 Staff: 2.5x more COVID
📌 Students: 6x more
📌 10x more 🦠 at school than in community stats
3/ Turns out schools may have missed up to 9 of 10 student cases and 7 of 10 staff cases — before better testing to detect and #StopTheSpread of COVID-19.
📌 District also mitigated risks:
✔️ hybrid
✔️ ¼ occupancy
✔️ 😷
✔️ 6 ft distancing
2/ Tracked COVID-19 cases Dec 11, 2020, to Jan 22, 2021, in an Atlanta district that included 8 elementary schools, 2 middle schools, and a high school. Students were in-person 4 days per week and wore masks, with desks spaced 3 to 6 feet apart. More kids in ES rooms than MS/HS.
3/ All cases confirmed by PCR testing. Secondary attack rate (SAR) — % of contacts who become infected— was calculated by setting (classroom, bus, indoor sports); student or staff; symptomatic or asymptomatic, and time of exposure.
1/ Really tired of reasonable, critical, school safety mitigations being mired in politics. Local "open schools/COVID just flu" groups are funded by GOP hardliners w/extreme views on masks, vaccines and need for public health regs.
2/ And yet, we may have a lot of room actually for common ground and a return to reason, a return to a common set of working facts — sensible precautions to keep school buildings open.
2/ A recent study in Boston found no significant differences in the # of infections in school districts in Massachusetts that adopted a 3-foot rule, when compared with those that required 6 feet of distance.
