Alberta reported more COVID-19 cases in September than any month prior data shows

September was arguably Alberta's worst month of the COVID-19 pandemic, provincial data suggests.

More Albertans tested positive for COVID-19 than in any month prior, and records for hospital and ICU admissions were set. Deaths in September also spiked, making it the deadliest month since January 2021.

Driving this situation was the infectious delta variant, insufficient public health measures, delayed government action and low vaccination rates, said Craig Jenne, an associate professor of microbiology, immunology and infectious diseases at the University of Calgary.

"When we backed off restrictions, the virus was able to exploit that and really move quite quickly through the unvaccinated," said Jenne, referring to the lifting of restrictions on indoor and outdoor gatherings, capacity limits and masks.

Alberta reported 45,665 COVID-19 cases last month, accounting for more than 15 per cent of all known cases in the province since the pandemic began.

Hospitalizations peaked at 1,122 on Sept. 27, while the number of patients in intensive care reached 268 on Sept. 28. There were 259 deaths.

The most deaths in a single month were 736 in December, which recorded a similar number of new cases to September.

Jenne said the efficacy of vaccines made the difference in the lower number of deaths.

"In areas without vaccine coverage, this delta variant is really causing havoc. And tragically, we're losing lives at a rate that's extremely disturbing over the last couple of weeks here in Alberta."

Vaccine uptake plateaued last summer, but has spiked since Alberta's proof of vaccination program was announced.

As of Sept. 30, 74.5 per cent of Albertans aged 12 and up have received two doses of vaccine; 83.8 per cent have received one jab.

Alberta delayed putting in restrictions

People were more cautious of the novel coronavirus a year ago, Jenne said.

Data shows Alberta reported 4,213 COVID-19 cases and 37 deaths in September 2020. As the second wave worsened, stricter protocols were implemented, he said.

That didn't happen as quickly this time.

Most COVID-19 restrictions were lifted on July 1, when there were 1,055 active cases. "We finally have the upper hand on the virus," said Premier Jason Kenney as he moved to reopen the economy 

The province began transitioning to its endemic response, with plans to lift nearly all COVID-19 protocols on Aug. 16. Data shows that in the first two weeks of August more than 5,000 people contracted COVID-19.

Public health experts warned against the move, which Alberta had based on data out of the United Kingdom, as the delta variant spread. The specific data behind the province's decision still hasn't been released publicly.

When Alberta paused its plan to lift all restrictions, Dr. Deena Hinshaw, Alberta's chief medical officer of health, cited rising hospitalizations and delta variant cases in pediatric patients.

Alberta Health Services started postponing surgeries in late August.

On Sept. 3, as known active cases reached 13,970, the province reintroduced restrictions: an indoor mask mandate and curfew on alcohol sales. It recommended unvaccinated people limit their close contacts and that employers pause return-to-work plans.

The province also announced it would pay $100 to people for getting vaccinated.

On Sept. 15, as active cases reached 18,641, Kenney declared a public health emergency, introduced multiple public health measures, announced a proof of vaccination program and apologized for the government's handling of the fourth wave.

Tyler Shandro resigned as health minister on Sept. 21, and Jason Copping took over. Copping did not respond to requests for an interview for this story.

Today, officials continue scrambling to create capacity in the health-care system.

Alberta is waiting for medical personnel from the military, Canadian Red Cross and Newfoundland and Labrador to arrive, with the hope they'll help boost ICU capacity. Hospitals may opt to transfer patients out of the province.

The Alberta government has been adamantly opposed to introducing strict new measures, which some have described as a firebreak, despite the calls from many health professionals.

Model predicts 4th wave peak in mid-October

Independent projections by Dean Karlen, a physics professor at the University of Victoria and member of the B.C. COVID-19 Modelling Group, suggests cases in Alberta could crest around mid-October.

Case counts are growing more slowly, likely due to public health measures and rising vaccine uptake, Karlen said.

"If constant behaviour is maintained, then one would expect a turnover in the coming weeks," he said, noting the full impact of restrictions isn't shown in the data yet.

Hospitalizations and ICU admissions will remain high, or rise, for the next week or two, Jenne predicted. They should start dropping as daily cases decrease.

Jenne suggests the key is for more Albertans to get vaccinated. In the short term, he said, they should consider being more cautious than the public health measures require, because those measures "are the bare minimum."
