1/10 Today's Omicron briefing . A 5-pt plan to blunt Omicron (slide 16): (1) Cut contacts by 50%; (2) acc boosters to HCW & vulnerable; (3) masking, distancing & ventilation (4) put treatments where they are most needed; (5) act now. #COVID19ON covid19-sciencetable.ca/sciencebrief/u…
2/10 Slide 4 & 5: Cases are rising across Ontario & Omicron will be dominant this week. #COVID19ON covid19-sciencetable.ca/sciencebrief/u…
3/10 Slide 6 & 7: South Africa itself – sometimes cited as evidence of O’s slower severity -- is now seeing hospitalizations rise with Omicron. But the rise in death there is less steep than in previous waves. #COVID19ON covid19-sciencetable.ca/sciencebrief/u…
4/10 Slide 8: Early data from Denmark are also showing rising hospital rates with Omicron. As with earlier strains. #COVID19ON covid19-sciencetable.ca/sciencebrief/u…
5/10 Slide 9: UK data show why we need boosters. Vaccine effectiveness against symptomatic disease drops to 35% with two doses of Pfizer, but is around 75% with three doses. #COVID19ON covid19-sciencetable.ca/sciencebrief/u…
6/10 Slide 10: One slide that lists all the key ways that we model Omicron differently than earlier strains. Worth reading to understand what we're facing. #COVID19ON covid19-sciencetable.ca/sciencebrief/u…
7/10 Slide 11: We model a “circuit breaker”: cutting contacts by 50% through public health measures, while rolling out boosters quickly. That could blunt the force of the Omicron wave. #COVID19ON covid19-sciencetable.ca/sciencebrief/u…
8/10 Slides 12-14: Hospitalizations are already rising on Ontario and are likely to rise substantially even if Omicron is 25% less severe than Delta. . #COVID19ON covid19-sciencetable.ca/sciencebrief/u…
9/10 Slide 15: Vulnerable Ontarians need third doses quickly. #COVID19ON covid19-sciencetable.ca/sciencebrief/u…

[1/20]: The Science Table completes its work this week. As our final work we are releasing our largest brief, a focus on the core of all health systems: primary care.
[2/20] This three-part series looks at primary care during the pandemic and outlines challenges and lessons learned: covid19-sciencetable.ca/science-briefs/
[3/20] Primary care offers a critical entry point into the health care system. More than 2 years of ongoing COVID-19 response has challenged the practice and capacity of primary care in Ontario, which have important implications that impact ongoing pandemic response and recovery.

We have likely entered a wave driven by the Omicron BA.5 subvariant.

Key Messages:
- The rise in hospitalizations will likely be smaller than earlier waves, but our hospitals are already very strained.
(1/17)
Key Messages (Cont'd):
- You can be re-infected by BA.5 even if you have recently been infected with an earlier strain.
- Non severe infections can still be disruptive to your life and increase long COVID risk.
(2/17)
Key Messages (Cont'd):
- The 3rd vaccine dose is critical to protect against severe disease.
- Going back to wearing a mask again in crowded indoor public spaces is a good way to protect yourself until the wave is done.

(1/11) We released new COVID-19 modelling for Ontario today. Key findings: we are well into wave 6 driven by highly transmissible BA.2 subvariant, waning immunity and lifting of public health measures. Follow this thread for more results covid19-sciencetable.ca/sciencebrief/u… Image
(2/11) There is significant uncertainty around the impact of case growth on our health system and deaths.
(3/11) Ontario’s COVID-19 wastewater signal increased, but growth has slowed down, suggesting that community transmission may have peaked. Image

1/5 New @COVIDSciOntario brief released today ‘Increased Screen Time for Children
and Youth During the COVID-19  Pandemic’ led by the Mental Health Working Group covid19-sciencetable.ca/sciencebrief/i… Image
2/5 The brief includes global & Ontario data gathered during the pandemic showing sharp increases in screen time for children & youth, especially during the closures of in-person learning and recreation.
3/5 Too much screen time has physical, mental and cognitive health harms. While this varies based on many factors, what is constant is that todays’ children and youth are exceeding screen time recommendations.
