Some health authorities stopped doing that, or recorded hospital-verified results as confirmed, so they could clear backlogs of tests faster. Health agencies are still figuring out how long it typically takes for a person’s COVID-19 symptoms to go away, and their processes for following up on infected people may vary.Ĭonfirmed versus presumptive: Originally, when Canadian health agencies tested people for COVID-19 and got a positive result, they were considered presumptive until the National Microbiology Laboratory in Winnipeg or a provincial lab confirmed it. Some provinces’ daily reports include their own active caseloads, but not all do. Subtracting recoveries and deaths from the total gives us the “active” cases, which you’ll see plotted in the top chart. Recovered versus active: When Canada’s cumulative cases are shown, they include recovered cases and deaths, though those are also charted separately. Daily tallies of new infections can also be significant because they show whether epidemics are accelerating or in decline.
The key word is “reported.” Some health authorities changed their methods for reporting or testing as the pandemic spread, or adjusted their schedules for releasing data.Ĭumulative versus new: Many of these charts show cumulative cases of COVID-19, or the total number to date, which shows the overall burden populations and health systems have had to deal with so far. What drops and spikes mean, and don’t mean: In the provincial and territorial data, you may see very sudden rises or falls in reported cases from one day to another. When comparing any two charts in this guide at a glance, please check how the scales differ. Putting all charts on the same scale would make smaller numbers, and the trends they show, too hard to see. Population numbers are the latest quarterly projections from Statistics CanadaĬheck the vertical axis: When charts measure populations of very different sizes, the vertical, or Y, axis has to be on a larger or smaller scale to fit the numbers. Unless otherwise specified, international data is from the database of JHU’s Center for Systems Science, based on numbers from national and regional health authorities.

Not all jurisdictions will update data every day, and their death tolls may not include travellers or dual citizens who die abroad. Although data suggests it causes a less severe form of COVID-19 than previous strains, the sheer size of caseloads means hospital systems in many areas are at risk of becoming quickly overwhelmed.Where are these numbers from? The Canadian data here is compiled manually at least once a day from the most recently available sources, including federal, provincial and territorial governments, Johns Hopkins University and COVID-19 Canada Open Data Working Group. Omicron’s rise from an unknown variant just two months ago to the dominant strain in many countries in the world is unprecedented. The region that includes the lower Midwestern states of Kansas, Missouri, Nebraska, and Iowa had the lowest proportion at 77.4%. Department of Health and Human Services now show omicron as dominant, with the South Central and Northeast regions showing the highest proportions at 98.2% and 98%, respectively. This marks a significant change from just two weeks earlier when delta accounted for 61.2% of cases.Īll 10 regions designated by the U.S. (Previous estimates from earlier weeks had been revised downward, for instance.) According to the tool, the once-dominant delta variant now only accounts for an estimated 4.6% of cases. The latest version includes data from the week of January 1, which is subject to change with additional updates. That incredible figure comes from the CDC’s freshly updated Nowcast tool, which uses sequencing data to estimate the proportion of variants within communities.
