|We updated and reposted this story almost every day for 582 days during the early days of the COVID-19 pandemic in Alberta and subsequent waves and want to thank you, our audience, for the enthusiastic feedback over those many months: we’re so glad you found it useful. We will no longer be updating it as of Nov. 2, 2021, but you can find all the latest important developments on COVID-19 in Alberta on our CBC Calgary and CBC Edmonton websites.|
|Keep an eye on the numbers|
As the COVID-19 pandemic continues, there are so many numbers flying around, it’s hard to keep track. Here, we’ll do our best to keep track for you.
Below you’ll find a series of curated charts, which will be updated as new information becomes available.
You’ll also find brief descriptions of how the data is measured, what it shows — and what it doesn’t show. This context is important to make sense of the numbers.
We’ll start with new cases.
These are the figures that tend to be front and centre in the daily updates about COVID-19.
There are some issues with relying on new-case data, alone, as the number of cases you detect is related to the amount testing you do and who you’re testing, (more on that in a moment).
But the advantage of looking at new cases is that they tend to be a leading indicator of how the virus is spreading, where it’s spreading, and whether the spread is speeding up or slowing down.
This first chart shows us the number of new cases identified each day since mid-March 2020, and a seven-day average of daily new cases.

|Alberta reported more COVID-19 cases in September than any month prior, data shows Oct 4, 2021|
|COVID’s R-value (or ability to spread) is once again rising in Alberta Jul 14, 2021|
|Alberta records lowest number of new COVID-19 cases in more than 10 months Jun 21, 2021|
|Alberta surpasses 25,000 active COVID-19 cases, reports 2,042 new cases May 8, 2021|
|Alberta once again shatters COVID-19 record with 1,854 new cases Dec 3, 2020|
A common question about these case numbers is why they don’t always match the numbers cited by Alberta’s chief medical officer of health, Dr. Deena Hinshaw, when she gives her public updates.
That’s because Alberta Health actually reports two sets of case numbers: a simplified net count and a regularly updated detailed count.
These two counts can vary slightly on some days because there is always a little uncertainty in the latest daily numbers.
Sometimes Alberta Health learns, days after counting a “probable” case of COVID-19, that it actually wasn’t a true case of the disease. In that event, the case is subtracted from the count. Other times, new information comes in late about a case that wasn’t initially included in a day’s tally. In that event, the case is added to that day’s count.
These fluctuations mean that Alberta Health is constantly adjusting its data, and it does so in two ways.
In the simplified numbers (which Dr. Hinshaw cites and are also posted on this section of the Alberta Health website), these fluctuations are netted out, so that the numbers reported each day add up to the total number of cases.
In the detailed data (which are posted on this other section of the Alberta Health website), the case counts are retroactively adjusted as new information comes in.
The data in the charts presented here come from the detailed data, not the simplified numbers, and thus are retroactively updated in the same way.

Vaccinations continue to roll out to more and more Albertans, but the pace of immunization has ebbed and flowed along with the supply of vaccine arriving from manufacturers to the federal government, which then distributes them to Alberta.
This next chart shows vaccination progress in terms of the total number of doses distributed to Alberta (the dotted line) and the total number of shots administered to Albertans (the solid line).

Health-care workers and residents of long-term care homes were among the first to receive the vaccines in Alberta, and many were given the full two doses on (or near) the manufacturers’ originally recommended schedules.
But as time went on, Alberta and other jurisdictions (both in Canada and around the world) changed strategy and opted to give single doses to more people as soon as possible, deferring the second doses until later on.
Vaccines were then largely rolled out by age, meaning older Albertans had earlier opportunities to be vaccinated.
In this next chart, you can see how the number of people who have received at least one dose compares with the number of unvaccinated people in each age range.

And finally, it’s helpful to look at the proportion of people who have been vaccinated.
This next chart shows the percentage of Albertans, by age, who have received at least one dose of vaccine, two doses, or no vaccination.

In mid-May 2021, Alberta Health also started publishing detailed geographic breakdowns of vaccination rates, by age.
This next interactive shows the percentage of population in each of 132 “local geographic areas” defined by Alberta Health.

The timing of your next COVID-19 vaccine may be more important than ever, as highly contagious Omicron subvariants are on the rise in Canada and waning immunity from previous vaccination and infection threatens to fuel another surge.
Canada is once again a hotbed for variants, with BA.2.12.1 now making up more than 40 per cent of COVID cases, while BA.4 and BA.5 are quickly gaining ground at more than 10 per cent combined in late May — a major jump from less than one per cent weeks earlier.
But the latest available federal data is weeks out of date and modelling experts CBC News spoke to estimate the true proportion of BA.4 and BA.5 cases is more than 20 per cent — and could be as high as 50 — with one of them likely to become dominant in the coming weeks.

In early 2021, Alberta Health started reporting more data on new variants of the virus that causes COVID-19.
Two variants of particular concern are known as B117 (which originated in the United Kingdom) and B1351 (which originated in South Africa). A variant known as P1 (which originated in Brazil) was later added to this list, and after that came the first confirmed cases of the B1617 variant, first identified in India.
These variants have numerous genetic mutations compared with the dominant type of virus that circulated in Alberta in 2020. They are of concern to public health officials because they are believed to transmit more easily from person to person.
The first case of alpha variant in Alberta was reported on Dec. 28, 2020, although it was actually detected earlier in December in a retrospective analysis of a sample that had been taken from a COVID-positive patient.
It takes additional time for a COVID-positive specimen to then be screened for variants of concern, and the tests for some variants can take longer than others. So, it’s often days later that a confirmed case is identified as a particular variant.
By February 2021, Alberta Health was testing all positive specimens for variants of concern. Prior to that, it was selectively testing specimens retrospectively, focusing on returning travellers who had tested positive for COVID-19.
Not all specimens can be screened, however. Due to limited genetic material or other technical issues, Alberta Health Services said in March 2021 that roughly 80 to 85 per cent of samples were being successfully screened.
As of May 1, 2021, Alberta Health announced it will stop screening all positive specimens for variants of concern.
The province said the move was necessary in order to maintain turnaround times and capacity in laboratories, which had been falling behind in the wake of the third wave that pushed case counts higher than they had ever been before.
Full screening resumed as of June 1, 2021, as case counts dropped and labs were no longer overwhelmed.
Then in September 2021, amid the surging case counts of the fourth wave, labs scaled back their variant screening again.
As a result of these changes, this next chart offers as complete of a picture as possible of variant spread, but the numbers prior to February 2021, throughout the month of May 2021, and from Sept. 10, 2021 onward are not directly comparable to the rest.
|New daily cases of variants of concern in Alberta. Each column represents the number of new cases of a variant of COVID-19 in Alberta on a given day.

The chart above shows total cases of each variant, by the date they were reported to Alberta Health, and reported as a seven-day moving average.
It can also be helpful to look at each variant relative to the other variants, to understand which versions of the virus are out-competing the others.
The alpha variant became dominant in Alberta in the spring, but later on the delta variant started to gain more and more of a foothold in the province.
This next chart shows each variant of concern, as a percentage of all new variant cases on a given day.
|Proportion of new variant COVID-19 cases in Alberta. Cases reported as a 7-day moving average. Due to the time it takes for a positive specimen to then be screened for variants, the most recent 2 days are excluded from this chart.

|The lambda COVID-19 variant is now spreading in Canada — here’s what you need to know Jul 8, 2021|
The original “wild type” of the virus (which contains no major mutations) still circulates in small numbers, Alberta Health said in June 2021, but variants make up the overwhelming majority of cases.
Alberta Health also breaks down where the variants have been detected, by health zone.
You can see the latest breakdown in this next table. Again, the totals will not reflect the total number of actual variant cases, due to the fact that not all samples are being screened.

Of course, Alberta is a big province, and outbreaks of the novel coronavirus often happen in localized areas.
At different times throughout the pandemic, different parts of the province have seen different degrees of virus spread.
So it’s useful to look at where new cases, in general, have happened, too.
|New cases by health zone|
Alberta Health breaks the province down into five broad health zones: South, Calgary, Central, Edmonton and North. (The names are pretty self-explanatory but if you want to see the precise boundaries of each zones, here’s a link to a PDF map).
This next chart shows new cases, by day, broken down by health zone.
|New cases reported by day and by health zone. At various times throughout the pandemic, different parts of the province have seen different degrees of spread. So it’s also useful to look at the where the new cases are happening, too. CBC. Source: Alberta Health. Click for a full screen view.|
Each column in this chart is a “stack” of cases, colour-coded by zone. Each “stack” adds up to the total number of new cases identified that day.
You can see how cases really started ramping up in mid-April 2020 in the Calgary Zone, in particular. This was largely related to the major outbreak at the Cargill slaughterhouse in High River, which is part of the Calgary Zone.
Later that month, you can see a large number of new cases in the South Zone. This was related to the outbreak at the JBS slaughterhouse and the wider outbreak in Brooks, at that time.
In early June 2020, you can see how new cases started growing in the Edmonton Zone again, after very few cases in and around the city for many weeks. The beginning of this trend was initially linked to several family gatherings in the city.
And then in October 2020 onward you can see the late-year surge in cases, which includes all health zones but has been most heavily concentrated in the Edmonton and Calgary areas.
That was followed by the “third wave” in early 2021, which saw the highest daily case counts of the entire pandemic.
So that’s the big picture, but the chart above can be a little hard to read if you’re mainly interested in recent cases.
This next chart shows the same information, but is limited to just the past three weeks, making it easier to see where new cases have been popping up. Tap on the bars or scroll your mouse over them to see specific numbers.

Some of these new cases will require hospitalization, which leads us to the next metric.
While much of the COVID-19 reporting focuses on the number of cases, experts are also closely tracking the number of hospitalizations.
Hospitalization data is more of a lagging indicator, as it typically takes longer for someone who gets sick with COVID-19 to end up in hospital than it does for them to test positive for the virus. There can also be delays in reporting from the hospitals, themselves, further adding to the lag in the aggregated data.
Still, tracking hospitalizations is useful because it not only helps gauge how much the disease has spread but also helps keep track of how much strain is being put on the health-care system. Hospital resources, of course, are finite and, in other parts of the world, COVID-19 cases have pushed those resources to — or beyond — their capacity.
|COVID-19 patients in Alberta hospitals. This next chart shows the number of patients in hospital — both those in intensive care and those outside of an ICU — each day since mid-March. Robson Fletcher CBC. Source: Alberta Health. Click for a full screen view.|
Prior to the second wave that hit Alberta in late 2020, hospitalizations had not reached a level anywhere near the capacity of Alberta’s critical-care system.
In November 2020, Hinshaw said the province had about 70 ICU beds set aside for COVID-19 patients and, as the number of patients approached that level, she said additional ICU beds could and would be devoted to people suffering from severe effects of the disease.
Alberta Health Services has said it monitors ICU capacity internally and is able to move patients, staff or equipment to match the need. It is also able to expand the overall ICU capacity, if need be, but there would be trade-offs to be made in other areas of the health-care system if that were to happen.
Specialized units — such as those intended for cardiac or neurological patients — can be repurposed for COVID-19 patients, but that would mean they won’t be available for people suffering from heart or brain conditions.
In May 2021, Alberta Health started publishing data on ICU capacity.
Alberta typically has 173 general, adult ICU beds across all its hospitals but, during the pandemic, that capacity has been expanded. The exact capacity on a given day can vary depending on the availability of trained staff.
This next chart shows the typical capacity, the day-to-day expanded capacity, and the number of COVID-19 patients and total patients in ICU.
|ICU occupancy and capacity in Alberta. Alberta Health says this data is collected at a “lagged interval” and numbers for a particular date may not match exactly with those reported elsewhere. Robson Fletcher CBC. Source: Alberta Health. Click for a full screen view.|
|More Albertans are in ICU with COVID-19 than ever — and it’s expected to get worse Sep 13, 2021|
|Albertans in their 20s, 30s, 40s and 50s are ending up in ICU with COVID-19 faster than ever before Apr 27, 2021|
ICU occupancy peaked in May 2021 and then started to decline, as more and more Albertans were vaccinated against COVID-19.
This next chart shows the number of patients in ICU, by their vaccination status:
- no vaccination.
- having had a single dose within 14 days of their diagnosis.
- having had a single dose more than 14 days before their diagnosis.
- having had a second dose within 14 days of their diagnosis.
- having had a second more than 14 days before their diagnosis (i.e. being fully vaccinated).
The chart is also annotated to show when one quarter and one half of the total population had received at least one dose, and when half of the population had received two doses.

Hundreds of Albertans have now died of COVID-19 but the rate of deaths has fluctuated throughout the pandemic.
This next chart shows the average number of deaths, by day.
There is often a lag between when a person dies and when it is reported to Alberta Health, so the number of deaths for the most recent few days tends to be under-reported.

For a more detailed, age-based breakdown of disease outcomes scroll down to the chart below labelled COVID-19 cases in Alberta, by age and status.
|Active and recovered cases|
Another term you often hear in discussion of COVID-19 is the number of “active” and “recovered” cases.
In general, Alberta Health says a recovered case is defined as:
- Anyone who is healthy after 14 days have passed, if they did not experience severe symptoms requiring hospitalization.
- Anyone who has gone 10 days from their date of discharge from hospital, if they did require hospitalization.
- Anyone who has received two negative tests, at least 24 hours apart.
This next chart depicts the total number of cases, broken down by the status of the patients: recovered, not-yet-recovered (but not in hospital), hospitalized or deceased.
|COVID-19 cases in Alberta by status. Each colour in a column represents the number of recovered, not-yet-recovered, hospitalized and deceased patients.

|Active COVID-19 cases in Alberta. *Daily case counts are based on PCR testing done by Alberta Health Services, but those testing protocols shifted in late December 2021 so that most people with symptoms are instead being asked to use at-home rapid test kits that aren’t included in official counts. So the true figure is thought to be far higher. Click for a full screen view.|
Again, this chart is a “big picture” look at the impact of the disease, provincewide.
But the number of active cases can vary quite a bit from place to place and from time to time.
So this next chart focuses on just the past three weeks, and breaks down the active caseload by health zone.
|Active cases by health zone, over the past 3 weeks. This next chart focuses on just the past three weeks, and breaks down the active caseload by health zone.

Beyond these five broad zones, Alberta Health breaks down the geography of the province even further.
It also subdivides those zones in 132 “local geographic areas” or LGAs. You can find more information about these areas here.
The right-hand column in the table below shows the latest active caseload for each of those local areas. The mini line charts in the adjacent column show the caseload history for each area. (Note the scale of vertical axis is not the same for each line chart; it’s specific to each local area’s case history).

|With 2,271 new cases, Alberta tops 200,000 cases of COVID-19 since start of the pandemic May 5, 2021|
|Alberta tops 100,000 total cases since start of COVID-19 pandemic Dec 30, 2020|
When talking about COVID-19 cases, it’s important to bear in mind that the number of confirmed cases doesn’t represent the number of actual cases — a figure we simply don’t know.
Many cases may have gone undetected because people didn’t have symptoms or didn’t seek testing for other reasons. People who have wanted a test haven’t always been able to get them, especially early in the outbreak.
Alberta’s testing protocols have changed significantly over time, leading to changes in which cases of COVID-19 are being caught and included in the provincial data — and those which go uncounted.
|How testing has changed over time|
In the earliest stages of the outbreak, testing focused on international travellers returning to Alberta and their close contacts.
On March 23, 2020 the province imposed stricter limits on who could get tested, giving a higher priority to those most at risk from COVID-19 and to health-care workers. Given that testing capacity was limited at that time, there were some important reasons for doing this, in order to get the maximum benefit out of the tests that were available. As testing capacity increased again, however, the criteria began to expand.
On April 7, 2020 the province started opening up tests to more symptomatic people, including a wider range of front-line workers such as firefighters, police and public-health inspectors, as well as anyone over the age of 65.
On April 8, 2020 the criteria were further expanded to include anyone with symptoms living in the Calgary health zone, which has seen the majority of cases so far in the province.
On April 14, 2020 the criteria were expanded again to include all Albertans showing symptoms.
|Coronavirus tracker: The cases, hospitalizations and vaccinations in your area|
On April 17, 2020 Alberta Health said it would further expand testing to include asymptomatic residents and staff in continuing care facilities experiencing outbreaks.
On May 11, 2020 asymptomatic testing was extended to people in the Calgary health zone, due to the high number of cases in the area. Similar asymptomatic testing was later offered in Brooks, as well, after the major outbreak in that city.
On May 29, 2020 asymptomatic testing was expanded to the entire province, meaning any Albertan wanting a test could seek one, even without symptoms of COVID-19.
On Sept. 17, 2020 asymptomatic testing for Albertans with no known exposure was scaled back to include “priority groups” only, such as residents and staff in congregate settings, health-care workers, teachers and other school staff, and people experiencing homelessness.
On Oct. 20, 2020, Dr. Hinshaw said the province would be “pressing pause on all asymptomatic testing in those who have no known exposure.” At that point, she said Alberta had completed more than 659,000 tests, in total, on asymptomatic people with no known exposure and, of those, only 0.11 per cent came back positive.
All these changes have led to major fluctuations in the number of tests being performed and who was being tested.
It’s important to bear these changes in mind when considering another measure health officials track: the positivity rate. This is simply the percentage of tests that come back positive.
This next chart depicts the positivity rate in Alberta over time.
|Positivity rate for COVID-19 tests in Alberta. Each dot depicts the percentage of positive tests on a given day. The line shows the average positivity rate over the previous seven days.

|Age of patients|
The age of Albertans who are diagnosed with COVID-19 has varied over the course of the pandemic.
At different times, the disease was being found more often in younger people, older people or middle-aged people due to a variety of factors.
This next chart shows the case rates in five broad age groups.
Because the number of Albertans in each age group varies widely, the rates are expressed in terms of new daily cases per 100,000 people in a given age range, to account for these population differences.
|New daily COVID-19 cases per 100,000 Albertans by age range. Expressed as a 7-day average. Robson Fletcher CBC. Source: Alberta Health. Cilck for a full screen view.|
You’ll notice the case rates among Albertans aged 80+ start to diverge from the other age groups in early 2021, especially in March. At this time, even as case rates rose sharply in the general population, the rate in this age group declined. Alberta Health attributes this difference to the fact that seniors were the first to get widely vaccinated.
We’ve heard that COVID-19 tends to hit older people harder than younger people, and this is true to a large extent but it doesn’t mean young people are immune.
This next chart shows the age ranges of patients who have been hospitalized in Alberta with the disease.

|Albertans diagnosed with COVID-19 are younger and end up in hospital less often. This is likely why April 28, 2020|
|Age breakdown for confirmed cases in Alberta hospitals shows not just seniors at risk March 30, 2020|
The number of people to have died from the disease is much more heavily weighted toward older adults, with most of the deaths among people aged 80 or over. Many of these people have died in long-term care homes.

|What you need to know about COVID-19 in Alberta on Monday, June 1, 2020|
Federal government to fast-track $2.2B to help municipalities.
- Alberta reported 34 new cases of COVID-19 on Monday, nearly double the number of new cases reported Sunday, bringing the total active cases to 400.
- Dr. Deena Hinshaw, Alberta’s chief medical officer of health, said the increase is a reminder that the pandemic is not over and that precautionary measures will be with us for some time.
- Two household gatherings in Edmonton are linked to at least 10 cases, which prompted a reminder from Hinshaw that people should not be sharing food or utensils and that it’s best to hold gatherings outdoors where distancing can be easily maintained.

|Self-assessment and support|
Alberta Health Services has an online self-assessment tool that you can use to determine if you have symptoms of COVID-19.
The province says Albertans who have returned to Canada from other countries must self-isolate. Unless your situation is critical and requires a call to 911, Albertans are advised to call Health Link at 811 before visiting a physician, hospital or other health-care facility.
If you have symptoms, even mild, you are to self-isolate for 10 days from the onset of symptoms.
Online resources are available for advice on handling stressful situations and ways to talk with children.
There is a 24-hour family violence information line at 310-1818 to get anonymous help in more than 170 languages, and Alberta’s One Line for Sexual Violence is available at 1-866-403-8000 from 9 am to 9 pm.

Everything from a new email destination for your questions to a dedicated page tracking coronavirus cases
We are all involved in a remarkable story.
As we move forward into the next few weeks and what most experts agree will be the most perilous part of the COVID-19 pandemic in Canada, we must not lose sight of the human face of this crisis.
Canadians are ill and some have died; we will tell their stories.
Canadians are fighting; we will showcase the first responders and health care workers working flat-out to save lives and the challenges they face.
Canadians are worrying; we will get answers, aggregate the best advice and hold our officials to account.
Canadians are helping; we will find the stories of hope and civic generosity that bring communities together.
We are seeing millions of Canadians turn to CBC News daily on TV, radio, digital and social media. Every word we publish, post and broadcast matters in the face of this voracious appetite for trusted news, context and the latest developments.
We cannot afford a misstep, and I’m grateful for the care and diligence that our staff bring to our reporting every day.
This is what public service journalism is all about.
- To manage the thousands of questions we’re getting from Canadians, we have set up a new email destination and will endeavour to answer as many as possible on all of our programs and platforms. Write to COVID@cbc.ca
- We launched a COVID-19 fact checking unit to expose falsehoods and disinformation around the global pandemic. See some of their early work here and here.
- We made CBC News Network (NN) freely available on cable and digital to all Canadians, here and abroad.
- We launched a COVID-19 newsletter. It’s already at 48,000 subscribers, our fastest-growing newsletter. A remarkable 70 per cent of users open this daily email. Sign up here.
- On CBC Radio One, we have extended the Current with Matt Galloway until noon in most time zones in order to provide you with the latest information and updates.
- Our coronavirus tracker is live. It will give you the latest data on the number of confirmed cases of COVID-19 as we know them, here and around the world.
- Our CBC News app will launch an update soon that will contain a COVID-19 guide to help our local audiences access resources, local stories and key video about their community.
- We’ve compiled local resources and updates for communities across Canada here.
- We have partnered with Canada’s private broadcasters to pool video coverage of official press briefings across the country in order to space out the number of crews present at any one event.
As I noted in an earlier blog, we temporarily paused our local 6 p.m. newscasts last week and moved quickly to shore up our ability to offer local and national programming on CBC TV and CBC News Network.
That decision was the result of us broadcasting more live events, press conferences and daily video than ever in the history of CBC News, which caused a logjam at our centralized resource desk in Toronto at the exact same time staffing levels there had dropped on account of COVID-19.
We also wanted to get ahead of the staffing crunch we anticipate in the next several weeks as more of our staff in newsrooms across the country are forced to self-isolate, work from home and potentially fall ill.
We are working in new ways with far fewer people available to do the resource-intensive work of television production.
We promised to assess the situation daily and bring the supper hour newscasts back as soon as possible — a commitment we took seriously.
Since last week, we’ve stabilized demands on our resources desk and can now channel some of our social media live streams through new software. We also created redundant systems for our television control rooms and resource work areas.
While it’s certainly not business as usual in these times, we will begin a gradual, staggered return to local news on CBC TV at 6 pm. We started today with the return of a half-hour newscast in Newfoundland and Labrador.
Beginning tomorrow, we will broadcast a half-hour of Compass from P.E.I. and a half-hour Atlantic newscast from Halifax covering Nova Scotia and New Brunswick.
We will take it one day at a time, continually adding back where we can while ensuring that nothing jeopardizes the essential services we intend to provide Canadians through to the very end of this crisis.
It’s important to remember that our commitment to local journalism on radio, TV, digital and social remains unchanged.
As always, thank you for your patience and continued support of CBC News at this unprecedented time.
