Wednesday was the 10th straight day fewer than 100 cases of COVID-19 were reported in Alberta. New, active, and serious cases of the novel coronavirus continue on the decline across the province as Alberta moves to lift nearly all pandemic restrictions on July 1.

Alberta’s active cases dropped to 1,055 by Wednesday, down 77 from the previous day. Of these, 158 were in the Edmonton region while 565 were in Calgary area. Hospitalizations dropped by five to 165 provincewide, including 34 people in ICU. Variant cases of COVID-19 make up about 68 per cent of Alberta’s active cases — 66 more variant cases were found.

During her final regularly-scheduled COVID-19 update on Tuesday, Alberta’s chief medical officer of health Dr. Deena Hinshaw said the worst of the pandemic is behind us, though she cautioned Albertans COVID-19 is still here, and to remember to take reasonable precautions.

Cases down, vaccines up

Declining cases come as more Albertans are protected from the disease by vaccines.

More than 4.3 million COVID-19 jabs have been given out in Alberta. Provincewide, 72.8 per cent of Albertans 12 and older have had one jab while 42.4 per cent of this age group are fully immunized.

Moderna and Pfizer’s vaccines have been shown to be very effective in protecting Albertans from both the wild and variant strains of COVID-19, according to provincial data. No information on AstraZeneca was available.

Moderna’s vaccines have been found to be about 82 per cent effective in preventing COVID-19 after a single jab while Pfizer’s has been about 73 per cent effective after just one dose. After two shots, this increases to 93 per cent for Moderna and about 90 per cent for Pfizer.

After just one dose, vaccines have been about 73 per cent effective against the Alpha variant, first identified in the U.K., and about 91 per cent effective after two doses. Similarly, one shot is about 75 per cent effective against the Gamma variant, first found in Brazil, and about 89 per cent effective after two.

Since January, the vast majority of new cases, severe disease, and deaths from COVID-19 have been in unvaccinated people.

Quebec's test positivity rate highest since May as COVID-19 infections climb – CBC.ca

Published

 on


While the number of new COVID-19 cases in Quebec remains low when compared to the peak of the third wave, the test positivity rate hit 1.4 per cent on Sunday.

That’s the highest it’s been since late May, and new public health data shows infections are on the rise.

Quebec has reported an average of 139 new cases a day over the past seven days, up from an average of 57 a week prior.

Quebec Public Health reported 154 new cases of COVID-19 on Monday and 347 new infections were identified on Friday and Saturday.

There have been no new deaths attributed to the disease since Thursday but there are 61 COVID-19 patients in hospital — of those, 17 are in intensive care.

Dr. Donald Vinh, an infectious diseases specialist at the McGill University Health Centre, told The Canadian Press that the current trends are concerning as they show “there is still ongoing community transmission.”

The increased rate is based on fewer tests, he said.

On May 31, Quebec recorded a test-positivity rate of 1.5 per cent based on 15,783 tests. While on Sunday, Quebec analyzed only 11,202 tests.

With that data in mind, Vinh said the concern lies in the future, as schools and university classes resume in late August  and September.

“If it’s already increased when we are in the ‘safe’ outdoors,” he said, “what’s going to happen when we’re in the indoors?”

Quebec’s public health institute reported that 84.6 per cent of residents 12 and up have received at least one dose of vaccine while 68 per cent are adequately vaccinated.

Delta variant stirs worldwide worry

Meanwhile, health officials in the United States are sounding the alarm over the rapid spread of the delta variant which is described as extremely contagious, even among vaccinated people. It may also cause more serious disease than earlier coronavirus strains.

“High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with delta can transmit the virus,” said Rochelle Walensky, head of the U.S. Centers for Disease Control (CDC) in a statement last week.

On Friday, the CDC released data from a study of an outbreak in Massachusetts in which it said three-quarters of those infected had been fully vaccinated.

The CDC recommends that Americans wear masks in areas with substantial transmission “regardless of vaccination status.”

The highly contagious variant, which was first discovered in India in late 2020, has spread around the world and now accounts for the majority of cases in Canada and various other countries. 

As of late July, the delta variant accounted for about five per cent of new cases in Quebec, compared to nearly 90 per cent of new cases in Ontario. 

For now, Quebec is continuing to scale back restrictions. For example, bars and restaurants are now officially allowed to serve alcohol until 1 a.m.— one hour longer than what was previously allowed. 

Stadiums, venues and festivals can welcome 15,000 spectators outdoors, up from 5,000.

U.S. vaccination rate hits the highest pace in weeks – CTV News

Published

 on


The rate of COVID-19 vaccinations in the United States continues to rise, a positive sign amid skyrocketing cases and hospitalizations after weeks of lagging inoculations.

The U.S. Centers for Disease Control and Prevention reported Sunday that 816,203 additional doses were administered, the fifth straight day the agency recorded more than 700,000 shots in arms. That brings the total number of doses administered to 346,456,669, according to the CDC numbers released Sunday.

The seven-day average of administered doses is now 662,529 per day, the highest average since July 7.

Additionally, Sunday was the third day in a row that the seven-day average of people getting their first shots topped 400,000. The last time that metric was over 400,000 was the July Fourth weekend.

That’s still less than a quarter of the peak in mid-April, when nearly 2 million people were getting their first shot each day.

If the U.S. picked up vaccinations to the April pace, it would take only a month and a half to reach all eligible people.

Per CDC data released Sunday, 168.4 million people are fully vaccinated, or 49.6% of the U.S. population. Among vaccine-eligible Americans — meaning those who are 12 and older — 58.1% are fully vaccinated.

Dr. Francis Collins, director of the National Institutes of Health, hopes the recent surge in cases driven by the Delta variant is changing the minds of the vaccine hesitant, he told CNN’s Jake Tapper Sunday. Collins noted that in the last two weeks, vaccination rates have increased 56% nationally.

“This may be a tipping point for those who have been hesitant to say, ‘OK, it’s time,'” Collins said. “I hope that’s what’s happening. That’s what desperately needs to happen if we’re going to get this Delta variant put back in its place.”

Overall, the seven-day average of people becoming fully vaccinated each day is at 247,385 people per day.

Twenty states have now fully vaccinated more than half of their residents, including Colorado, Connecticut, Hawaii, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New Mexico, New York, Oregon, Rhode Island, Vermont, Virginia and Washington state, as well as Washington, DC.

On the other hand, the states with the lowest percentage of their population vaccinated are Alabama and Mississippi, which have 34% and 35% of their residents vaccinated, respectively.

Correction: An earlier version of this story and headline gave the wrong timing for when the doses were administered. The Centers for Disease Control and Prevention reported the additional doses Sunday, but it’s not clear when they were all administered.

Delta spreads 'like wildfire' as doctors study whether it makes patients sicker – CTV News

Published

 on


LOS ANGELES —
With a new wave of COVID-19 infections fuelled by the Delta variant striking countries worldwide, disease experts are scrambling to learn whether the latest version of coronavirus is making people – mainly the unvaccinated – sicker than before.

The U.S. Centers for Disease Control and Prevention warned that Delta, first identified in India and now dominant worldwide, is “likely more severe” than earlier versions of the virus, according to an internal report made public on Friday.

The agency cited research in Canada, Singapore and Scotland showing that people infected with the Delta variant were more likely to be hospitalized than patients earlier in the pandemic.

In interviews with Reuters, disease experts said the three papers suggest a greater risk from the variant, but the study populations are limited and the findings have not yet been reviewed by outside experts. Doctors treating patients infected with Delta described a more rapid onset of COVID-19 symptoms, and in many regions an overall increase serious cases.

But the experts said more work is needed to compare outcomes among larger numbers of individuals in epidemiologic studies to sort out whether one variant causes more severe disease than another.

“It’s difficult to pin down increase in severity and population bias,” said Lawrence Young, a virologist at the UK’s Warwick Medical School.

In addition, it is likely that the extraordinary rate of Delta transmission is also contributing to a greater number of severe cases arriving at hospitals, the experts said.

Delta is as contagious as chickenpox and far more contagious than the common cold or flu, according to the CDC report.

Shane Crotty, a virologist at the La Jolla Institute for Immunology in San Diego, said the clearest indication that the variant may cause more severe disease comes from the Scotland study, which found that Delta roughly doubled the risk of hospitalization compared to an earlier version.

The majority of hospitalizations and deaths from coronavirus in the United States are occurring in people who have not been vaccinated. But there is evidence that the shots are less effective in people with compromised immune systems, including the elderly.

For vaccinated, otherwise healthy individuals, the odds are that if they contract COVID-19 they will only experience asymptomatic or mild disease, said Dr. Gregory Poland, infectious disease expert at the Mayo Clinic.

“But they can pass it on to family members and others who may not be so lucky,” Poland said. “We have to be vaccinated and masked or we will, for the fourth time now, endure another surge and out of that will come worse variants.”

‘FULL-ON FLAMES’

The rate of severe illness, especially in regions where vaccination rates are low, is again straining healthcare workers on the front lines of the pandemic.

“This is like a wildfire, this is not a smouldering campfire. It is full-on flames right now,” said Dr. Michelle Barron, senior medical director of infection prevention and control at Colorado’s UCHealth.

Research from China suggesting that the Delta variant replicates much faster and generates 1,000 times more virus in the body compared to the original strain highlights the biggest danger of this new wave, Barron said.

“It is hard to tell if they are more sick because of the Delta variant or if they would have been more sick anyway,” she said.

Other doctors said patients infected with Delta appear to become ill more quickly, and in some cases with more severe symptoms, than those they treated earlier in the pandemic.

“We are seeing more patients requiring oxygen sooner,” said Dr. Benjamin Barlow, chief medical officer at American Family Care, a 28-state chain of urgent care clinics.

At his clinic in Birmingham, Alabama, Barlow said that around 20 per cent of patients are testing positive for COVID-19, compared with two to three per cent a few weeks ago. Patients are assessed at that time for potential hospital admission and oxygen support.

David Montefiori, director of the Laboratory for AIDS Vaccine Research and Development at Duke University Medical Center, said the Delta variant is more infectious and leads to faster onset of illness – particularly for the unvaccinated.

“Frankly there’s a severity that comes from this variant that is a little more severe,” Montefiori said on a webcast last week. “It’s not just easier to transmit, it makes you sicker.”
