The teacher became symptomatic on May 19, but continued to work for 2 days before receiving a test on May 21.
"during this time <of active COVID symptoms>, the <unvaccinated> teacher read aloud unmasked to the class despite school requirements to mask while indoors."
Also note, all of her students were too young to be vaccinated.
Now, the 24 kids in the class were wearing their masks & "all classrooms had portable high-efficiency particulate air filters and doors and windows were left open" but...
N=24 students exposed, N=22 students tested for SARS-CoV-2, N=12 tested positive.
"The attack rate in the two rows seated closest to the teacher’s desk was 80% (8of 10) & was 28% (4 of 14) in the three back rows."
"six of 18 students in a separate grade at the school, all also too young for vaccination, received positive SARS-CoV-2 test results. Eight additional cases were also identified, all in parents and siblings of students in these two grades."
"In addition to the documented infections in the two initial grades, cases were identified in one student each from four other grades. These four students were siblings of three students with cases in the index patient’s (stage whisper: TEACHER'S) class.
In this teacher-student-family-friend network, a sleepover with three students from the 2nd class, they all tested positive.
Three of the adults who caught the virus in the outbreak had been vaccinated.
DELTA IS A BEAST (as my brilliant colleague @JehnML says).
To protect yourself & others:
Get vaccinated
AND
Wear masks
AND
Keep distant indoors
AND
Don't be in social settings when symptomatic
AND
most of all
recognize that this pandemic is still raging.

Let's talk about the ways that humans socially learn, bc without that context it may be hard to understand how we got to the "folks taking livestock medication & shitting themselves in public" situation (🧵)
As humans, our adaptive cognitive architecture for social learning is <chef's kiss>
(also, y'all should go ahead & follow Prof @MichelleAKline bc she is really in the know about all this)
From an individual perspective, learning things through "trial & error" or "guess & check" is fraught with pitfalls. At BEST it can take a LOT of time, limiting how much a person can learn in lifetime...
And now time for an #2021MMM Intermission

Art is at the heart of teaching about nature. These rock drawings are in a Yankunytjatjara and Pitjantjatjara children’s “classroom” at the base of Uluru, a place used for thousands of years to pass on key knowledge of the world & how all living things are connected. #2021MMM
Every year March Mammal Madness Art Team creates vibrant & compelling imagery of all combatants. #2021MMM saw an incredible #LevelUp in the team's artwork. You can bring this art into your own space in while simultaneously supporting the Art Team! society6.com/mammalmadness
ONLY THREE MORE BATTLES in #2021MMM
[gif is Homer Simpson ringing bell & wearing a sandwich board that says the end is near]
TONIGHT THE FINAL ROAR!!!
Kangaroo vs. Mountain Tapir
Saber-Toothed Anchovy vs. Harpy Eagle #2021MMM
The encounters will occur in randomly selected habitats from 4 possibilities: freshwater swamp forest, dwarf forest, semi-arid desert, & seagrass meadow... and will be announced at the start of the battle! #2021MMM
FIRST UP from the Sea Beasties Division: No. 1 seed #1 Saber-Toothed Anchovy (Monosmilus chureloides) vs No. 2 seed Midgardia Seastar (Midgardia xandaros) #2021MMM
Tonight's Battle is a collaboration with @je_light, and I frantically double-checked some things with @DrewLab an hour ago. #2021MMM [gif is rabbit running late]
Saber-Toothed Anchovy has had a pretty uneventful tournament so far. Round 1 was easy, with a swish of the tail sending Copepod out of the field of battle & Rounds 2 & 3 ended with Pink Vent Fish & Vampire Squid meals #NomNomNom#2021MMM
