1/Our back-to-school guidance for schools in Ontario is out!
This framework reflects a year’s worth of evidence, lived experience, and tremendous stakeholder engagement. covid19-sciencetable.ca/sciencebrief/s…
2/Here’s what the brief touches on:
3/Our group came at this with the shared perspective:
School is the “essential work” of children. Educators + school staff are critical to students’ work.
We have heard from educators, administrators, clinicians and child health advocates how turbulent this year has been.
4/ When we treat schools as “essential" places, we no longer use school closures as primary measures of pandemic control.
And we afford protective measures to keep schools healthier for students, staff and their families.
5/Arguably a familiar visual - the Hierarchy of Hazard Controls, applied to school-based measures
Note:
Paid sick days (and flexibility to work from home) helps to keep infections out of school, so it's included as a key measure
6/Also – no blanket, province-wide strategy for school-based measures.
We are calling for a regional approach by PHUs. This includes rural, remote and Indigenous communities.
We need to consider both disease burden and community transmission rates.
7/ What’s not in the brief (and needs its own space):
- educational recovery
- curricular reforms
- MH supports
- access to school-based rehab supports (e.g. PT, OT, SLP) as some kids have fallen behind/regressed in abilities/health status.
These are urgent and important
8/ There are recs for activities (music, sports, clubs) in different risk scenarios. We've heard these are a lifeline for kids and youth.
And a Ventilation road map for school boards - for both long-term changes that they can make, as well as short term temporary solutions
9/With schools around the corner, it's so important that we enable a healthy return to school in the Fall.
Let's take stock of how far we've come this past year:
- PH capacity
- VACCINES
- more evidence
1/As we close a 2nd abysmal school year, this comprehensive report explores challenges in ON schools.
Fundamentally, in high-epi context, more introductions into school
= increased risk of spread in school and into community without additional measures thestar.com/news/investiga…
2/Testing + symptom screening act as red light
= prevent introductions
BUT an individual in school during their infectious period will still lead to cohort dismissal
👆🏾 why #COVIDZero in community + health/safety measures in school needed for stable in-person instruction
3/QC kept schools open + shut down gatherings elsewhere for months; still saw cohort dismissals in high-epi settings ~GTA
Screening is a vertical strategy that seeks out 1 specific pestilence. It's hard to find cases that cannot afford to be found.
Let's see where #OutdoorLearning falls within the hierarchy of [infectious] hazard controls
Ventilation is usually considered an engineering control
But outdoor learning changes the way students and staff work, so one could argue it's an administrative control too #twofer 2/
BENEFITS of #OutdoorLearning include: 1) higher ventilation 2) improved air quality
= better mental/physical health outcomes AND reduced infection risk
Evidence in table 👇🏾
(from a useful paper in @DavidElfstrom's useful🧵- suggest reading both!):
This approach does NOT necessarily detect large # asymptomatic/symptomatic individuals (see serology studies) esp if insufficient resources to follow-up cases and trace contacts.
What can asymptomatic screening (with rapid Ag or PCR test) ADD?
3/
1/It's the eve of provincial announcements on schools reopening for in-person instruction.
Households are under stress and experts are divided on whether schools are unicorns or infernos.
Everyone wants to do right by kids, who have borne so much throughout this pandemic.
2/As @AmyGreerKalisz, @AshTuite and I wrote in July, the most effective strategy in schools is to decrease community transmission.
In that context, superspreader events in schools rarely occurred in the Fall, and PH measures seemed to be effective. theglobeandmail.com/opinion/articl…
3/But local and global data are conflicted re: the role kids play in #SARSCoV2 transmission, with few studies involving comprehensive testing of asymptomatic high-risk contacts.
(recall: up to 50% of kids with COVID are asymptomatic, so symptom-based testing will miss cases).
