WHAT'S NEW THIS WEEK?
About 1 in 314 people in Canada is currently infected (111,000-185,000 infections/week).
The most recent estimate for the United States (May 18) is 1 in 275 infected (www.pmc19.com/data/index.php).
Expected excess mortality due to COVID-19 in Canada is MODERATE (4%, Forecast score 4).
Infections in Canada this week are expected to result in 500 hospitalizations, 110 premature deaths (people who die at least 1 year earlier than they would without COVID) and 4,200 new long COVID cases serious enough to limit daily life activities.
About 2.1% of people in Canada are infected and/or experiencing life activity-limiting long COVID this week.
The estimated cost of hospitalizations from this week's infections in Canada is $10.5M.
Hospitalizations are expected to require 0.8% of Canada's staffed hospital beds for three weeks (CIHI: average duration of COVID hospitalizations).

CONFIDENCE OF ESTIMATES
The average confidence interval since Dec 5/21 is 6.6%.
Average annual infection prevalence, infection fatality and hospitalization rates for Canada from 2022-2024 are similar to UK data from ONS and Ward et al 2024 (prevalence 1.01X UK, IFR 1.01X UK, IHR 1.01X UK; p>0.05).

The real-time infection hospitalisation and fatality risk across the COVID-19 pandemic in England - Nature Communications
The severity of SARS-CoV-2 infection varied over the course of the pandemic due to factors such as changes in variant characteristics and population immunity from previous infection or vaccination. Here, the authors estimate infection hospitalisation and infection fatality rates in England over time from the start of the pandemic until March 2023.
Based on population age structure and health, and hospital capacity, Canada's population IFR is expected to be 1.01-1.05X the UK population IFR.

COVID outbreak risk remains in #ONhealth hospitals without layers of protection.
Universal masking in ALL areas of #Ontario hospitals is essential for safe healthcare access.
Let regional decision-makers know this is a priority.
