Five ways to reduce and evaluate risk in a potential sixth wave of COVID-19

Published

 on

As most provinces and territories lift COVID-19 public health measures, Canadians are left to assess their own risk level amid signs of a sixth wave.

Dr. Theresa Tam, Canada’s chief public health officer, said last month it’s important to look at the amount of COVID-19 in your community and what activity you are undertaking.

“Is it outside? Is it inside? Is it crowded? Who am I going to be with?”

Tam said it’s also important to take into account your personal health situation and whether you are around people who are at greater risk, such as elderly parents or unvaccinated children.

Here are five ways to reduce your risk:

Masks

Quebec and Prince Edward Island are the only two provinces extending their mask mandates until the end of the month.

“Masks do matter,” P.E.I.’s public health officer, Dr. Heather Morrison, said Tuesday. “Masks will be one of the last measures lifted.”

Other provinces have resisted calls to reimpose public health restrictions, including mask mandates.

Tam noted it’s now a personal choice in most provinces.

“Think about who you’re with and maybe they’re at higher risk — so, having that consideration for others.”

Vaccination

Vaccination rates vary across the country, but research has shown the shots can help reduce severe outcomes.

Some experts said this week they worry government messaging about the current state of the pandemic could affect uptake of additional doses.

Eligibility for fourth doses is expanding in some provinces after the National Advisory Committee on Immunization recommended people 70 and older get a second booster.

“It’s hard to motivate people to get boosters when they want to believe this is done,” said Dr. Kelly Grindrod, an associate professor at the University of Waterloo’s School of Pharmacy.

“And the question is, do we have to keep living through disaster levels for people to stay engaged enough that they want to protect themselves?”

Online tools

More than a million people have turned to an online calculator that was created to help Canadians manage their COVID-19 risk.

My COVID-19 Visit Risk Decision Aid, which is free online, was first created during the second wave of COVID-19 in fall 2020.

“People were starting to ask these questions,” said Dr. Samir Sinha, director of health policy research at the National Institute on Ageing. “Is it safe to visit with others? Are there safer ways to visit with others?”

Sinha said the institute turned it into a three-minute risk calculator in spring 2021.

The tool, he said, can be a valuable resource as people navigate what appears to be a sixth wave with few restrictions.

“We’re not guaranteeing anybody a safe, in-person visit,” said Sinha. “We’re just giving people an opportunity to understand how they can visit more safely with others.

“It’s about providing people with education and the tools.”

Wastewater data

Many cities have been collecting and distributing information about COVID-19 in wastewater.

Kevin Frankowski, executive director of Advancing Canadian Water Assets at the University of Calgary, said it’s one piece of information for people to consider.

“There are significant advantages to wastewater monitoring,” he said. “It’s inclusive. Every single person who uses the bathroom contributes to that signal, it doesn’t require the right testing policy or the willingness to go get tested.

“It’s also unbiased. Wastewater doesn’t lie.”

But he said it’s important to be careful with the data. As an example, he noted wastewater numbers were going up as hospitalizations dropped in Alberta.

“Both of those statements are correct,” he explained. “One possible interpretation is that the severity of the disease continues to decline. Infection is still there, but it’s not resulting in symptoms that make you go to the hospital.”

Frankowski said the data should be used as one source for people to incorporate into their decision making.

“One of our project co-leads, Dr. Casey Hubert … makes the analogy between the COVID (wastewater) tracker and the weather forecast app,” he said, explaining you can check both before you head out.

“Do I need an umbrella? Do I need a mask?”

Stay home when sick

Most jurisdictions recommend staying home when sick.

In Alberta, for example, officials note that someone with COVID-19 can spread the virus to others for up to 10 days.

“The risk of spread in fully vaccinated people is lower after five days, but it still exists,” the province’s website says.

The website adds that isolation helps prevent spread by reducing the number of people you could infect by staying home and avoiding others.

Measles cases stabilize in Montreal – CityNews Montreal

Published

 on


The number of measles cases has stabilized, according to the Montreal Public Health.

Since March 25, there have been no contaminations reported within the community.

“Our teams have identified all contact cases of measles,” said media relations advisor Geneviève Paradis. “It’s a laborious task: each measles case produces hundreds of contacts.”

300x250x1

All community transmission cases since February 2024 have been caused by returning travelers who were either unvaccinated or partially vaccinated.

Currently, there are 18 measles cases in Montreal – with 46 total in Quebec. This according to the April 18 figures from the provincial government.

“With the summer vacations approaching, if you’re travelling, it is essential to check if you are protected against measles,” explained Paradis.

According to Montreal Public Health, a person needs to have received two doses after the age of 12 months to be immunized against the virus.

They’ve launched a vaccination campaign throughout the region, and currently, 11,341 people have been vaccinated against measles in Montreal between March 19 and April 15.

Vaccination is also being provided in schools and at local service points.

“The vaccination operation is under the responsibility of the five CIUSSS of the territory,” concluded Paradis.

Risk of bird flu spreading to humans is ‘enormous concern’, says WHO – The Guardian

Published

 on


The World Health Organization has raised concerns about the spread of H5N1 bird flu, which has an “extraordinarily high” mortality rate in humans.

An outbreak that began in 2020 has led to the deaths or killing of tens of millions of poultry. Most recently, the spread of the virus within several mammal species, including in domestic cattle in the US, has increased the risk of spillover to humans, the WHO said.

“This remains I think an enormous concern,” the UN health agency’s chief scientist, Jeremy Farrar, told reporters in Geneva.

300x250x1

Cows and goats joined the list of species affected last month – a surprising development for experts because they were not thought susceptible to this type of influenza. US authorities reported this month that a person in Texas was recovering from bird flu after being exposed to dairy cattle, with 16 herds across six states infected apparently after exposure to wild birds.

The A(H5N1) variant has become “a global zoonotic animal pandemic”, Farrar said.

“The great concern of course is that in … infecting ducks and chickens and then increasingly mammals, that virus now evolves and develops the ability to infect humans and then critically the ability to go from human to human,” he added.

So far, there is no evidence that H5N1 is spreading between humans. But in the hundreds of cases where humans have been infected through contact with animals over the past 20 years, “the mortality rate is extraordinarily high”, Farrar said, because humans have no natural immunity to the virus.

From 2003 to 2024, 889 cases and 463 deaths caused by H5N1 have been reported worldwide from 23 countries, according to the WHO, putting the case fatality rate at 52%.

The recent US case of human infection after contact with an infected mammal highlights the increased risk. When “you come into the mammalian population, then you’re getting closer to humans”, Farrar said, warning that “this virus is just looking for new, novel hosts”.

Farrar called for increased monitoring, saying it was “very important understanding how many human infections are happening … because that’s where adaptation [of the virus] will happen”.

“It’s a tragic thing to say, but if I get infected with H5N1 and I die, that’s the end of it,” he said. “If I go around the community and I spread it to somebody else then you start the cycle.”

He said efforts were under way towards the development of vaccines and therapeutics for H5N1, and stressed the need to ensure that regional and national health authorities around the world had the capacity to diagnose the virus.

This was being done so that “if H5N1 did come across to humans, with human-to-human transmission”, the world would be “in a position to immediately respond”, Farrar said, calling for equitable access to vaccines, therapeutics and diagnostics.

Navigating the world of degenerative illness: Conference focuses on helping patients and caregivers – Ottawa Citizen

Published

“I’m not saying it’s society’s problem, but there should be recognition of the load that caregivers are taking.”

When former CEO Bruce Wood was diagnosed with young onset Alzheimer’s disease in 2016, he made a point of talking publicly about the illness to help others. When he could no longer do so, that duty fell to his wife, Lisa Raitt.

The former senior federal cabinet minister, lawyer and mother has made speaking about her husband’s illness part of her busy life, even when it is difficult, which it often is. She sees it as a duty to help people better understand the disease and to support caregivers like her.

“I always accept these invitations.”

Raitt will be keynote speaker at an Ottawa conference this weekend aimed at helping patients and their caregivers navigate the often complex systems of care once they are diagnosed with neurological illnesses such as Alzheimer’s.

The Enhancing Access to Care conference, sponsored by the University of Ottawa’s Brain and Mind Research Institute, will include sessions on barriers to accessing care for rural residents, the latest research for neurodegenerative illnesses, including Parkinson’s disease and dementia, information on the regional geriatric program and Raitt’s talk on the challenges of care for young-onset Alzheimer’s.

The conference is a recognition of the difficulties patients and their caregivers can have accessing the help they need.

Wood was diagnosed when he was 56 and Raitt was 47. It was a shock. Raitt said she wanted people to think about the fact that “sometimes it’s Alzheimer’s” — meaning possible symptoms shouldn’t be dismissed just because of a person’s age.

In the early days after his diagnoses, Wood’s disease seemed to move slowly, she said, and they were able to travel and “do all of our bucket-list things.” But then it progressed and life became increasingly difficult.

“We had a very specific set of circumstances where Bruce was becoming very combative, not just aggressive, but aggressive that was threatening to our lives in the house. When you are in it, you can’t negotiate because you are drowning and just trying to keep your head up.”

Raitt said she thought it was important that people hear the realities of the disease “because I am not the only one who is going through this or went through this. I believe there’s an obligation for me to at least give some kind of colour to the reality so that others can recognize it.”

Wood is now in a long-term care home, something Raitt says she fought “with every fibre.” She acknowledges he is receiving better care than he could receive at home and that she probably waited too long to do so.

“I think what could have helped me is somebody saying they are better off in a long-term care facility because he gets better care than I could have provided.”

Raitt said she also hoped members of the medical community heard her story to start to think about the possibility of young onset Alzheimer’s when a patient had symptoms that might include increasing problems with planning, problem solving, attention and emotions.

She also noted that the vast majority of caregivers, like her, are women. Raitt, a lawyer, belonged to a support group of caregivers in similar circumstances and says almost all of them decided to retire early because of the pressures of caring on top of their work.

“I didn’t have the choice to retire. I’ve got two kids in university and a husband with special needs. That takes extra cash — and I continue to work for my own sanity, too” she said. “But the reality is caregivers are the ones taking a load off society and society couldn’t function without us. I’m not saying it’s society’s problem, but there should be recognition of the load that caregivers are taking.”

The conference, which will be held Saturday at the RA Centre, is aimed at people with neurological conditions and their care partners. In addition to presentations, organizations will be on-site to offer information about other services available in the community, including from traditionally marginalized group “who might not know there are services specific to their needs,” said Dr. Lisa Walker, a clinical neuropsychologist who is co-lead of the uOttawa Brain and Mind Research Institute’s neurodegeneration pillar.

It is the first event of its kind for the University of Ottawa Brain and Mind Research Institute. Typically, events are geared toward research, Walker said.

It is difficult living with neurodegenerative conditions, she said, and can be a daunting task to access care. Sometimes, it is available, but people don’t know how to find it.

She said the shortage of family doctors was an added burden for people to understand the supports available in the community. “There are many excellent services that people can access, but they don’t know they exist and can’t access them.”

Among them are services through the regional geriatric program and the Dementia Society of Ottawa and Renfrew County. One of the speakers will talk about Ontario 211, a help line to help people access social services, programs and community supports.

Walker said the conference would also address the burden on informal caregivers, as family members and friends who care for loved ones are called.

“It is a huge burden of care, both from a practical standpoint and an emotional standpoint.”

The conference runs from 9 a.m. to 5 p.m. on Saturday. The conference, including lunch, is free and the venue is accessible. More information is available online: https://www.uottawa.ca/research-innovation/brain/events/enhancing-access-care
