A recent COVID-19 outbreak at a southern Ontario fitness studio is illustrating how certain indoor settings can provide a perfect storm for superspreading events.
The studio, a downtown Hamilton SPINCO location, has been connected to 69 cases of COVID-19 as of Wednesday, despite screening customers, operating at 50 per cent capacity and keeping the recommended two-metre radius around bikes.
So how did so many cases originate there? And does it raise concern about how the novel coronavirus can spread in a gym setting?
“Certainly this event makes you wonder that,” said Dr. Matthew Oughton, an infectious disease expert at Jewish General Hospital and McGill University in Montreal.
“I can see where this could lead to perhaps gyms having serious restrictions placed on them if they want to avoid similar superspreading events.”
Ontario and Quebec recently reintroduced closures at gyms in virus hotspots, including Toronto, Montreal and Ottawa, for a four-week period to help limit spread.
And Dr. Barbara Yaffe, Ontario’s associate chief medical officer, said Wednesday authorities are reviewing guidelines for fitness studios across the province after the Hamilton outbreak.
Oughton says gyms and fitness studios have a few strikes against them when it comes to tailoring them for the pandemic.
They’re operating almost exclusively indoors, which makes for poorer ventilation, and patrons aren’t usually masked when engaging in strenuous exercise.
High-impact activity also leads to heavier breathing, which means droplets are being expelled from peoples’ mouths at an accelerated rate — and being propelled further distances.
Dr. Andrew Morris, a professor of medicine at the University of Toronto, likens it to throwing a ball. The harder you throw, the further it goes.
“We still don’t have a perfect understanding of this,” he said. “But we do know that when people are exercising vigorously, the volume and distance of what comes out of their mouth and their lungs is dramatically different than when somebody is speaking (in a normal way).”
If people are shouting, cheering or singing — which often happens in a spin class where music is blaring and instructors spew out encouragement to keep participants’ intensity up — that can make things worse.
“And if you mix that in with a space that may not have proper ventilation, there is risk for a lot of spread to occur,” Morris said.
Dr. Ilan Schwartz, an infectious disease expert with the University of Alberta, says spin classes may pose more risk than other group settings because of the bikes themselves. In theory, the rapidly spinning wheels could aerosolize droplets by flinging them further distances.
“I haven’t seen any studies of this, but theoretically it makes sense,” he said.
“I think going to the gym isn’t necessarily high-risk, unless individuals are close together and there’s poor ventilation. But there might be specific circumstances that could make it higher-risk, where something with fast, moving parts (or) a rapidly moving fan can generate aerosols as well.”
But Morris says the real danger comes when people are spewing out droplets in a poorly ventilated space.
The prolonged length of time spent in a spin class, typically one hour, and the number of people in the room will also impact risk.
Not all fitness classes will present the same dangers, he added.
A low-impact yoga class where hearts aren’t racing and breathing is kept under control seems safer than a high-impact spin class, but not if it’s crowded and poorly ventilated.
A dance class, where participants are crisscrossing into airspace previously occupied by others, can be risky as well in the same environment.
“Assuming that room has relatively poor ventilation, that’s the kind of setting where yes, you’d be concerned about the potential for transmission,” Oughton said. “But if you had the exact same room with an excellent HVAC system, or the same room where windows were kept open … those are the kinds of things you could do to reduce the risk.”
Morris says finding ways to make these activities safer is always better than banning them.
Masks, while uncomfortable when working out, can be worn in most instances, he said. Improving ventilation and limiting numbers of people even further can also help.
“If we’re going to be successful, we can’t keep telling people they can’t have these things,” Morris said. “We need to be able to point to something and say ‘this is the better choice.’”
Schwartz says frequent hand-cleaning and the sanitization of equipment should also be kept in mind, even if surface transmission isn’t as concerning as it was earlier in the pandemic.
“And for now I think it’s probably a good idea to avoid spin classes,” he added.
Oughton foresees people taking their workouts outdoors in new ways over the winter if gyms and fitness centres are deemed too risky.
That could mean dusting off the skates or ski boots.
“I think this is going to re-emphasize the safety and the necessity of being able to get some activity and fresh air outside,” he said.
“Hopefully we find new appreciation for outdoor winter sports that we can all enjoy.”

Calgary COVID outbreak of at least 49 active cases linked to recent wedding: officials – National Post
CALGARY — Alberta Health says 49 active COVID-19 cases have been linked to a wedding in Calgary earlier this month.
The health agency says the wedding had a large number of Albertans from different households.
Alberta Health spokesman Tom McMillan says aggressive contact tracing is underway to identify anyone who may have been exposed to make sure they are isolating and getting tested.
He did not say how many people attended the wedding and says specifics about individual cases cannot be disclosed because of patient confidentiality.
COVID-19 restrictions implemented by the province say a maximum of 100 people can attend outdoor and indoor seated events, such as wedding ceremonies, funeral services, movie theatres, indoor arts and culture performances.
McMillan says the city of Calgary has recently seen several outbreaks linked to social gatherings.
“This is a reminder to all Albertans that this virus is still here and any social gathering carries a risk of exposure,” he said in an email Tuesday.
“It is important that nobody attend if they are feeling ill with even mild symptoms, or if they are awaiting test results.”
He says it is also important that organizers do everything possible to comply with the public health guidance in place, including having enough space for physical distancing between cohorts, following gathering size restrictions and avoiding sharing food and utensils.
People with dementia among hardest hit by COVID-19 health restrictions – CBC.ca
Before COVID-19, Lyne Gauthier did her best to keep her husband’s mind from slipping away by organizing activities they had enjoyed together before he was diagnosed with early-onset Alzheimer’s disease.
She would visit the long term facility where Yves Dessureault, 66, has lived for three years and take him on simple outings.
“We’d go grocery shopping, go out for an ice cream cone,” said Gauthier. Sometimes they would just “listen to music and dance.”
But then the coronavirus hit, and there were no more outings.
There were also no more services like pet therapy or music therapy within the facility due to the pandemic.
Gauthier says she has watched her husband deteriorate dramatically in the past six months. He’s now considered to be in the late stages of Alzheimer’s.
“I think COVID has really fast-tracked the progression of his symptoms,” she said.
Gauthier feels the health rules that curtailed their outings and deprived Dessureault of face-to-face contact robbed him of precious time as a husband, father and grandfather.
At his care home, there is little mingling these days and many residents eat their meals in their rooms.
The social isolation has left him more fragile, both physically and emotionally, said Gauthier.
Since the spring, she says, Dessureault appears more upset and anxious. His balance has gotten worse and even the simplest words have lost their meaning.
“If I want to show him where we’d like to sit, I need to tap the seat and do more gestures,” said Gauthier.
“There is a lot he can’t do anymore.”
Worsening symptoms linked to lockdowns
During the pandemic, many residents in long-term care experienced rapid cognitive decline, increased depression and more behavioural symptoms such as wandering and agitation, said Dr. Isabelle Vedel, a public health physician and associate professor in McGill University’s Department of Family Medicine.
There is some preliminary research from the United States and the U.K. suggesting people with dementia were hit the hardest by the virus.
Not only were they at an increased risk of being infected and of dying from COVID-19, but there were thousands of so-called excess deaths — meaning many more people died than the average for the same period in previous years.
Vedel fears the same will be true in Canada.
“People living in long-term care were extremely affected by the pandemic,” said Vedel. “Eighty per cent of the deaths happened in long-term care in Canada, and we know that approximately 80 per cent of people in long-term care have dementia.”
With funding from the Canadian Institutes for Health Research, Vedel is leading a research project in collaboration with Alzheimer’s societies across Canada that will measure the deaths of people with dementia during the pandemic.
It will also examine what impact the disruption of services and access to health care may have had on their lives.
For instance, during the first wave of the pandemic, Quebec feared hospitals would be overrun, so long-term care facilities were asked not to send people to the ER, said Vedel.
“It’s very probable that even though they had acute illnesses, they were not sent to the emergency department, so they didn’t receive the appropriate care they needed.”
Lessons for the 2nd wave
Maintaining services as much as possible during subsequent waves of the virus is paramount, Vedel said.
People with dementia rely on home care, community services, family physicians and caregivers. If there are obstacles to getting these services, people with dementia will decline and fall between the cracks, she said.
“We have to make an extra effort for them and make sure that they can be well cared for during the pandemic,” said Vedel.
She expects the research group will have statistics and recommendations in the spring.
Disruptions, reimposed restrictions
With parts of Canada now firmly in a second wave of the pandemic, all the changing health precautions and disruption can be especially distressing for people with dementia.
In Quebec, for instance, more and more regions are in red zones, where visits are once again limited in long-term care homes and private seniors’ residences. The partial lockdown also means many programs are suspended.
The goal is to limit contacts and keep the virus from sweeping through those facilities as it did in the first wave.
The directive to wear masks or face coverings to slow the spread poses a problem for these patients because it’s harder to read facial expressions, which they rely on to communicate and interact.
Overmedication is another problem: As patients get more agitated, more medication is being prescribed, including anti-psychotic drugs to calm them down, said Nouha Ben Gaied, the director of research and development for the Federation of Quebec Alzheimer Societies.
These drugs, “are inappropriate to use for people with dementia and they can cause more harm than benefits” said Ben Gaied.
Ben Gaied hopes Quebec’s health ministry has learned lessons from the first wave.
A spokesperson for the ministry said it has introduced measures to better protect this population and reduce the number of excess deaths.
That includes better access to a family doctor and improving the transition between primary care and specialized services, said Marie-Louise Harvey.
The government has also recruited nearly 10,000 new patient attendants, about 7,000 of whom are already working in the system. The rest are still in training.
The province has asked long-term care homes to limit the movement of employees between long-term care homes as much as possible.
Infection control and prevention is also being closely watched.
Even so, since September, some of the new outbreaks in long-term care homes or private seniors’ residences in Quebec have been in units for people with a cognitive impairment like Alzheimer’s or dementia.
‘He deserves better’
Gauthier’s greatest fear is her husband getting COVID.
She’s concerned about the high number of cases in Quebec, and what will happen to her husband if the partial lockdown is extended beyond the end of the month.
She’s doing everything she can to help her husband connect, though now that his care home is in a red zone, all she can offer are video chats with family, walks on the grounds or jaunts in the car to listen to music.
One of the activities that still makes Dessureault light up, she says, is a visit with his grandchildren — even if it is through a window or on FaceTime. Dessureault loves children, she says, and seeing them brings out his goofy, playful side.
“I find my husband for a few more seconds, a minute. It’s as if my husband is back,” said Gauthier, fighting to hold back tears. “The emotions are there. They connect. It’s just simple.”
She says she knows he’s still there, underneath the disease, but his quality of life has spiralled downward during the pandemic.
“He deserves better,” said Gauthier, who sometimes finds it hard to keep her spirits up.
“As a society, we can do better.”
