Finally dug into the details of the California teacher who was a Typhoid Mary to her students...

I'll just quote from the CDC report (cdc.gov/mmwr/volumes/7…)

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.
