Isn't this how we'd hope to handle these situations at work? 👇
2/ Worker 😨, calling boss: Hey, I sat next to someone w/ COVID-19 for 7 hours yesterday, but am vaccinated; can I come into work and wear a mask? Have lunch in the cafeteria?
BOSS: No, work from home. Some vaccinated people have spread COVID-19. Get tested. Then come back.
3/ Worker 😨, calling boss: Has anyone in my work group had COVID-19 recently? I'm off to see my immunocompromised elderly mom, wanted to know.
BOSS: Sure, I'll check, but didn't you get that notice we sent, about case in building? Ought to get a test, in case you crossed paths.
4/ Worker 😨, calling boss: Hey, I sat 37 inches away from Sally all day yesterday, and now I noticed she's out with COVID-19. We were masked, but not sure if I ought to come in today.
BOSS: Hey, to be on the safe side, why don't you use your paid sick leave and go get a test.
5/ Worker 😨, calling boss? Hey, I was masked and sat 37 inches from Danny for hours and he has COVID-19. Am I a close contact who should monitor my health, work from home, get tested?
BOSS: Yes! You're a close contact. The whole team will need a test, work from home for 3 days.
5/ If any of these situations were in schools, the answer would have been to come in.
Schools already miss a huge number of asymptomatic cases without required, frequent testing.
Can we afford not to take extra precautions and notify families for the cases they do spot?
That last one should be 6/. Time for coffee!
7/ Schools will not consider most kids a close contact if they are masked. The standards for close contact definition are totally different (masked adult contacts ARE supposed to be careful.)
Do we think kids wear masks better than adults?
8/ Adults are close contacts within 6 feet. Kids are not. Kids get and spread COVID-19 easily and frequently, so this does not make logical sense.
In fact, many aerosol scientists have argued that EVERYONE in room should be considered a close contact because #COVIDIsAirborne.
2/ There was some inaccurate information being put forth that these machines were not ionizers, because they were not listed by the California @AirResources Board as ionization devices.
But these machines do indeed have an ionizer. 👇
3/ The use of additive and electronic air cleaning devices, often marketed with HEPA in the name although they ARE NOT HEPA cleaners, has come under scrutiny this year.
1/ Thought-provoking 🧵 on how Delta variant may be more dependent on larger clusters of infection (super-spreading!) to surge. The “k” factor or variability could be more. But add a “super emitter” to a low air flow room and 💥, then multiply by how often this is happening…
2/ The obvious applicability is one would reduce the following:
📌Eliminate situations like indoor eating at schools, in community cafeterias, and improve airflow in rooms that are ideal for superspreading. (<1 ACH for sure; close to 2 ACH should be next priority, and so on).
3/ We would also:
📌Try to screen out next super emitter from turning infectious… We’d test kids in classrooms with known case, for instance, and not just assume “had a mask on so can’t have gotten it.” Many private schools have such required pooled testing or rapid testing.
2/☝️This shows about a 1% transmission rate while all kids were wearing masks in this study.
The caveat (in the earlier data we reviewed) was surveillance testing wasn’t utilized to catch many asymptomatic kids. In places where testing was used, like Omaha, they found 6x cases.
3/ Other studies found COVID-19 infected many more kids than known. Serology in MS found >10x COVID-19 cases in kids as known. (Many MS kids getting reinfected; devastating outcomes.)
INOVA/GMU study: HUGE undercount here.
Any known exposure = kid ~3x more likely infected
13,540 babies/preK <4yoa (100%)
20,181 kids (ALL <12 +teens to 19) (38%)
8,957 young adults, age 20-24 (56%)
25,156 age 25-34 (46%)
12,605 age 35-44 (33%)
15,892 age 45-64 (30%)
4,519 age 65-84 (20%)
1,115 of 85+ (35%)
TOTAL: 100,051 unvaxed
There isn't a record of some of the federally distributed shots, so our amount of vaccinated could be greater for some of the adults. Maybe 5% more? 10%?
90,000 unvaccinated is still plenty for a virus to attack.
Unlike our neighbors in DC and Maryland, we have no indoor mask mandate. We are fully open. The bars and restaurants are full. With indoor gatherings and back to school full-time, there is a lot of human fuel for #DeltaVariant to burn through and spread rapidly in our community.
Uh oh… APS Policy: Don’t notify kids/staff if they were near a COVID-19 case, if were wearing a mask? Hmmm…Confusing. An upset parent just sent us this APS note about contact tracing and asked us if we understood it. APS cites CDC…
BUT a 3-minute search of CDC turns up a guide for what to do if you have COVID, which CLEARLY states people you were near while wearing masks ARE CLOSE CONTACTS and must be notified. Is it any wonder why parents are worried ‘bout back to school… especially for unvaxed kids < 12?
WHY would we not err on side of at least notification? If nothing else? How many APS families include multigenerational members, caregivers for elderly, pregnant moms, new babies, or immune-compromised members at more risk from COVID-19?
