In Canada and abroad, COVID-19 super-spreaders could be anywhere – CTV News

Published

 on


TORONTO —
You may have heard of “patient 31” in South Korea, a woman who was thought to be the source of thousands of COVID-19 infections in that country. Or more recently, a man in India who had returned from Europe and reportedly infected people in more than a dozen villages. They are known as “super-spreaders” – individuals who can infect a large number of people easily.

The World Health Organization estimates someone with COVID-19 can infect between 2 and 2.5 individuals, but super-spreaders infect a large number of people, often in a crowded and busy environment like a church or a conference.

“In a weird way, that seems to be the pattern for this disease. It’s not just that it spreads universally across the landscape,” said CTV News’ science and technology specialist Dan Riskin.

“You get these hot spots where a whole bunch of people get infected at once, and when that happens you can call that person a super-spreader.”

In Canada, while no specific individual has yet been identified as super-spreader, there have been clusters, or hot spots, from coast-to-coast involving a significant number of people.

More than 60 cases of the 135 cases identified in Newfoundland and Labrador are tied to two wakes held at a funeral home on March 15. The funeral home has since been closed as the investigation continues.

“Many of our numbers right now are related to this one cluster, either directly or indirectly, and that will have an influence on what we see,” Dr. Janice Fitzerald, the province’s chief medical officer of health told reporters over the weekend, when asked when she might expect to see cases peak in the province.

On the other side of the country, up to 32 people infected with the virus could be tied directly or indirectly to the Pacific Dental Conference held in Vancouver earlier this month, according to the province’s medical health officer, Dr. Bonnie Henry. One of those attendees has since died.

Some of the factors that can make a patient a super spreader may be related to biology – if they produce more of a virus, for example, or if they take longer to recover from an infection and spread the virus over a longer period, according to experts.

Historic research showed that Mary Mallon, a cook in New York City infamously known as “Typhoid Mary”, was the source of a typhoid fever outbreak in the early 1900s that infected thousands, despite never having any symptoms herself. Scientists are researching how much of a role silent carriers of COVID-19 – those who exhibit no symptoms – play in unknowingly spreading the disease.

This is why self-isolation is important, Riskin said.

“It’s a reminder that for Canadians, we all have to take this seriously, because you don’t know if you’re that one person who unknowingly could infect thousands.”

People with diabetes in lower-income areas at higher risk for amputations: report

Published

 on

TORONTO – The Canadian Institute for Health Information says more than 7,000 people with diabetes undergo a leg, foot or toe amputation every year — and the majority of those procedures could have been prevented.

The report issued today says people with diabetes living in the lowest-income neighbourhoods are three times more likely to have an amputation than those living in the highest-income communities.

It also says people with diabetes living in remote communities are at higher risk of leg amputations than those living in urban centres.

Erin Pichora, CIHI’s program lead for population health, says lack of access to a primary-care provider to help people manage diabetes is one likely factor behind the inequalities.

She says disparities are also likely in access to specialists who can treat diabetic wounds on people’s feet — including podiatrists and chiropodists — before they worsen.

Diabetes Canada says the report shows the importance of ensuring people with diabetes have equitable access to the care and resources they need.

“People living with diabetes who undergo amputations face significant emotional and financial distress,” Laura O’Driscoll, senior manager of policy at Diabetes Canada, said in an emailed statement to The Canadian Press.

“We need to ensure that everyone with diabetes has affordable, timely access to the medications, devices, education, and care needed to manage their condition and prevent complications like amputation.”

The CIHI researchers reviewed hospital records from across Canada for fiscal years 2020-2021 and 2022-2023 and found about 7,720 “lower limb” amputations associated with diabetes per year among people 18 and older.

Each year there were about 3,080 hospitalizations for “above-ankle” leg amputations and 4,640 hospitalizations for “ankle-and-below” amputations, including feet and toes.

Evacuation orders near Grand Forks, B.C., downgraded, but U.S. fire is still a threat

Published

 on

 

GRAND FORKS, B.C. – Wildfire officials say an evacuation order for the B.C. southern Interior town of Grand Forks, has been downgraded to an alert, even as an out-of-control wildfire in Washington state surges north and threatens to cross the border.

The Regional District of Kootenay Boundary says residents must be ready to leave at a moment’s notice since the Goosmus wildfire remains a risk to life and safety.

Emergency Info BC says the updated alert, posted late Wednesday, is in place for west of Highway 41 and south of Highway 3, as well as properties west of Highway 3 from Sleepy Hollow Rd to Phoenix Rd.

It is advising everyone under alert to review their emergency plans and stock a grab-and-go bag.

The district says that when necessary, residents should leave via Highway 3, go to the Jack Goddard Memorial Arena in Grand Forks, and wait in their vehicles until the reception centre opens.

The district says if you cannot evacuate at that time, you should call 911.

The BC Wildfire Service dashboard says the fire was discovered Wednesday and is about two square kilometres in size.

Mark Stephens, director of the district’s emergency operations centre, called it “a very fast-moving and developing situation.”

“We ask everyone to stay vigilant and to keep checking the (regional district’s) website for information,” he said in an online statement.

Calgary officers punched, Tasered man at hotel before he died: police watchdog

Published

 on

 

Calgary police fired stun guns at a man and punched him in the head before he was put in restraints and died, investigators with Alberta’s police watchdog said Wednesday.

The Alberta Serious Incident Response Team, or ASIRT, said in a release that police were called on Sept. 17 about a man loitering near the check-in desk of the Carriage House Hotel and Conference Centre.

The agency said the man appeared dazed when he was told to leave by an officer. The man tried to pick up items from the floor that weren’t there.

When the officer pointed a Taser at the man, ordering him again to leave, ASIRT said the man raised his hands and started to walk out. He told police: “I don’t want to die.”

“The lone officer tells the male to stop talking and continues to point the weapon at him,” the agency said.

It said two other officers began walking through the main doors toward the man, and he stopped and repeated that he didn’t want to die. The first officer put away his Taser and tried to grab the man.

“At no point during the interaction had the male been identified, nor was he ever told he was being detained or under arrest,” ASIRT said.

It said the man physically resisted the officer and was tackled to the ground by another officer, who then punched the man in the head. At this point, ASIRT said the three officers fought the man for 3 1/2 minutes with “various uses of force.”

The man was put in handcuffs and leg restraints, and a spit mask was placed on his mouth, said ASIRT.

“The male is noted to be bleeding from the mouth and vomits,” the agency said.

It said seven minutes later, the man was sedated by emergency crews and left lying face down. After three more minutes, he was found to be unresponsive.

“The male was then provided medical care but declared deceased at the scene.”

Calgary police said in a release that same day that officers were called to the hotel for a man “acting erratically” in the lobby who was refusing to leave. They said the man wasn’t co-operating and was still being combative after a Taser was pulled out.

Police said the man was pepper-sprayed and taken into custody and shortly after went into medical distress.

A police spokeswoman said Wednesday the three officers involved have been placed on a standard 30-day leave.

“We know there’s a family and a community grieving this loss and our thoughts are with them during this difficult time,” said a statement.

ASIRT, which looks into serious allegations of police misconduct, said its investigation will examine the use of force by the officers.
