1/ This is why we need to #AlertTheClass, and the lack of mandatory #COVID19 #testing for all in place before opening #schools here may be a big mistake.
The #DeltaVariant is surging in #Arlington County, but the people who spread it "feel just fine."

2/ #Delta's #KillerAdvantage:
Infected folks spread 🦠 for 1.8 days before they ever get first symptom.
Symptoms show up 5.8 days AFTER infection, on average, says Hong Kong research team.
Spreaders also have far higher viral load.
74% infections from presymptomatic spread

3/ One bit of good news in this: Vaccinated individuals were 65% less likely to infect someone, but the estimate is based on a very small sample size.
4/ Our contact tracing/quarantine policies are never going to keep up with #DeltaVariant.
If someone is infectious in class, they'll have TWO days to spread virus.
The masks APS gave kids may leak 40-50% of particles; virus will float for >hour in rooms w/o better air cleaning.

5/ Hypothetical: The first infected kid feels sick on weekend, gets tested (MAYBE).
APS hopefully finds out, then decides to only quarantine 1 kid who they remember got w/i 3 feet.
The rest of the class is not told ANYTHING, because APS policy is NOT to #AlertTheClass.

6/ Oops! Looks like +2 kids got infected.
Now the 2 new infected kids are spreading for 2 days before they ever show a symptom — if they ever show a symptom.
At this point, a good policy ought to trigger an intervention to test and identify cases from ALL those who shared air.

4a/ Side Not: There won't be #equity when it comes to who's getting sick the most.
It's likely to gonna be the kids with the worst masks, who didn't have $1 per KF94.
Families gotta work, gotta put kids in school. School must be safer! PLEASE consider giving #BetterMasks, APS!
