These graphics show just how deeply COVID-19 has infiltrated Alberta

It was inevitable, the premier said.

Though there were only dozens of cases of thecoronavirus SARS-CoV-2 reported in Canada, health officials were resigned that the pandemic would eventually spread into Alberta.

A news bulletin went out in the late afternoon March 5, with few details aside from confirmation that a presumptive case had been confirmed.

Less than an hour later, the province's chief medical officer of health took to the podium.

"Uh, you all know, my name is Dr. Deena Hinshaw," she said. "I'm here, as you know, to provide an update on COVID-19 in Alberta."

Hinshaw went on to provide more details: the presumptive case was a woman in her 50s who had been on board the Grand Princess cruise ship,which was quarantined off the coast of California.

The provincial government sent word to travellers returning from outside Canada: monitor your symptoms. The next day, Alberta Premier Jason Kenney commented on the first case.

"Obviously, we are concerned about this initial presumptive case," he said."Given the breadth of this virus around the world, [it was] likely inevitable that we would see some manifestation of it here in Alberta."

Nearly a year later, Hinshawneeded to introduce herself to Albertans no longer she had become a fixture when it came to herdaily updates on cases, hospitalizations, outbreaks and deaths.

But the province she delivered her messages to had changed.

Since that first case a year ago,133,202 other Albertans have tested positive for the virus. Nearly 2,000 Albertans have died.

"It is important to remember that every part of this province, at every sector of society, has been touched by this virus," Hinshaw said recently.

Active COVID-19 case rates in Alberta

Active COVID-19 cases, per 100,000 people, from April 2020 to February 2021. Map is divided into 132 'local geographic areas,' as defined by Alberta Health.

A crisis in long-term care

Allan Pasutto, 86, of Penhold, received hisfirst dose of the COVID-19 vaccination in late February of this year.

"I'm very happy to be alive," Pasutto said.

But during the darkest early days of the pandemic, a vaccine seemed a world away. Whispers of promising research trials still cautioned developments were months, if not years, away.

In the early months of the pandemic, the virus devastated multiple long-term care homes across Alberta. At the McKenzie Towne Continuing Care Centre in Calgary, more than 100 residents and staff tested positive, and 20 people died.

"It was absolutely horrifying," Renee Laboucanesaid in December, reflecting on the outbreak that claimed the life of her mother.

As the pandemic grew,outbreaks at long-term care homes became typical while remaining terrifying realities for the families involved.

Cases at some long-term care centres approached 100, while one Edmontonlong-term care centre became the deadliest in the province, with 55 deaths.

In mid-February, the premier announcedthat all residents in long-term careand designated supportive living had received their second shot of the vaccine.

Butthe grim reality remains that two of every three deaths linked to COVID-19 in Alberta came within these facilities.

Slaughterhouses become front lines

In mid-April, cases at a Cargill slaughterhouse in High River skyrocketed, with at least 950 staff nearly half its workforce testingpositive for COVID-19. The outbreak remains thelargest workplace outbreakin Canada.

It was illustrative of the cold working environments within which experts say COVID-19 thrives.

And it wasn't just Cargill. In late April, the small community ofBrooks went from just a few cases of COVID-19 to one of the province's biggest hotspots.

Three employees of the JBS Foods meat-processing plant were diagnosed with COVID-19 in mid-April, and by the end of the month more than 300 workers had been diagnosed and nearly 900 total cases were recorded throughout the city.

It meant that Brooks which has 0.3 per cent of the province's population represented 26 per cent of its active cases.

Similar rapid spreadwas felt this yearat the Olymelslaughterhouse in Red Deer, Alta., which has been linked to at least 500 cases of COVID-19 and four deaths.

That slaughterhouse temporarily shut down Feb. 15, but not before it drew a warning from Alberta Health Services that cautioned that one in five of its1,850 workers was believed to be infected.

Sixty per cent, AHS said, held at least one job outside the slaughterhouse.

For those who have felt loss as outbreaks proliferate among workforces, the grief remains longafter case counts go down.

Ariana Quesada, 16, filed a formal complaint against Cargillin early January, asking police to investigate potential criminal negligence in the death of her father.

"We have filed a complaint ... to finally bring justice to my dad ... to finally hold Cargill accountable for what they did," Quesada said at the time, fighting back tears.

From large complexes to small gatherings

Earlier this year, total cases at Alberta's oilsands sites crept past 1,000. Correctional centres in communities like Peace River popped up on Alberta's outbreak list, while hamlets like Gunnsaw cases flare up too.

Though Calgary and Edmonton frequently were found atop Alberta's list of active cases last fall, rural Alberta saw the highest active rates of COVID-19 in late January.

Of course, the spread of the virus wasn't concentrated to certain facilities or communities. It spread in churches, hospitals, small businesses, fitness studios and within households.

It devastated families and it shut down businesses, and the economic impacts and the lasting griefof the past year will continue to be felt long after the province has enough vaccines to go around.

Alberta's chief medical officer of health says the patient is a woman in her 50s who lives in the Calgary zone. She was on board the Grand Princess cruise ship before it was quarantined off the coast of California, returning to Alberta on Feb. 21 and self-isolating at home on Feb. 28.

On March 6, 2020, one day after Hinshaw announced the first presumptive case of COVID-19 in the province,she took to the podium again,reading from a page of prepared remarks.

"I want to let you know of news that I learned in this past hour. We have a second presumptive case of COVID-19 in Alberta," she said, adding public health would be following up with close contacts.

"I want to stress that the riskof getting sick from COVID-19 remains low at this time in Alberta.However, with these recent developments, we are anticipating this risk may increase in the weeks to come."
