Can I use a mouth shield instead of a mask? Your COVID-19 questions answered – CBC.ca

We’re taking on your questions about the pandemic. Send them to us via email at COVID@cbc.ca, and we’ll answer as many as we can. We’re putting some of your questions to the experts during The National and on CBC News Network. We’re also publishing them here on our website. You’re keeping us busy. So far, we’ve received more than 52,000 emails from across Canada and beyond.

Can mouth shields replace cloth masks?

Mask questions continue to be a major theme in our inbox, but this week, a bunch of you are writing to ask us about mouth shields. The plastic guards cover the lower half of a person’s face and are marketed for stopping the spit of food-service workers.

Tal S. is wondering if they can be worn instead of non-medical masks. 

The experts say no.

“I don’t think they’re a really good alternative at all,” said Dr. Susy Hota, medical director for infection prevention and control at the University Health Network in Toronto, in a recent interview on The National.

“These are developed for the food-service industry, and they’re really not studied or designed for this purpose at all.”

Of course, the purpose of wearing non-medical face coverings, according to public health officials, is to protect others from the droplets spewing from your mouth and nose.

There is also evidence that non-medical masks may offer some protection for the wearer, too. But because mouth shields are not tight fitting and are open at the top, Hota said, there are “lots of opportunities for droplets to get in.” 

“I would avoid using them,” she said.

Colin Furness, an infection control epidemiologist and assistant professor at the University of Toronto, also said he’s “not a fan” because mouth shields don’t collect droplets like a mask would.

“Cloth masks actually get damp,” Furness said in an email. “But I’m guessing [shields] don’t have rivulets of water running down them, and that would be because the droplets aren’t staying.”

Instead, he explained, the droplets are just forced sideways around the shield.

“Full face shields have the same problem,” Furness said. Read more about the issues with face shields here.

I’m hosting an outdoor wedding. Is it OK to dance?

With the gradual lifting of limits on the size of gatherings, Canadians are asking us about good practices for get-togethers.

Joanne L. told us she’s hosting a backyard wedding at her home in Aurora, Ont., but she wasn’t sure if dancing was advisable.

The answer is: It’s complicated.

Dancing, like singing, is one of the activities that is still considered to be higher risk. In some settings, like in restaurants and bars in the province of Ontario, for example, they fall under explicit restrictions and regulations.

For example, performers must:

  • Work for the establishment.
  • Maintain a physical distance of at least two metres from every other person.
  • Be separated from others with a physical barrier, like plexiglass.

However, the Ontario Ministry of Health explained in an email that those regulations don’t apply to events outside of restaurants and bars. 

That means dancing is allowed at your backyard wedding, though distancing and gathering limits still apply. Outdoors, that’s up to 50 people for the service or ceremony and up to 100 people for the reception. 

But just because it’s allowed doesn’t mean it’s without risk. It’s particularly risky, Furness said, because people tend to get close and start breathing harder, “which means expelling more droplets and expelling them further.”

Dr. Anand Kumar, a professor of medicine at the University of Manitoba, added that loud speech, shouting and singing also increase the potential distance of droplet spread. He recommended that guests wear masks “particularly if [there is] loud music which would force participants to shout.”

Health Canada also advises wearing non-medical masks when distancing is difficult. Furness suggested painting big circles on the dance floor, two metres apart, to keep people from getting too close. But he warned that things could become challenging when guests start cutting loose. 

“The problem with a wedding is that it’s not certain that people would keep their mask on or their distance from each other,” he said.

That said, being outdoors would offer “excellent protection,” Furness said, “and either really hot weather or a firm breeze is even more protective.” But the benefits of being outdoors might be reduced if you’ve erected a tent.

If it has open sides with a breeze coming through, Furness said he’d consider that “outdoors.” But if it has walls, it’s indoors.

“I did attend one family dinner in a tent with sides earlier this month, and it was easily the riskiest thing I have done since COVID began,” he said. “I wouldn’t do that again for any reason.”

Is there a safer way to hug?

It’s not just weddings that make people want to get close. The pandemic has left many Canadians longing to wrap their arms around their friends and family.

But what about people not inside your bubble? Carol F. wrote to us to ask if there is a safer way to squeeze them.

“It’s a difficult one to call,” Dr. Lynora Saxinger, an infectious disease physician at the University of Alberta in Edmonton, said in an interview on The National.

“We know that routine closeness can lead to increased transmission.”

Hugs, for example, should be reserved as a “special occasion,” she said.

If you were to give someone a hug, brief contact while wearing masks and with your faces turned away ‘would be the safest way to do it,’ one expert says, adding it would be a good idea to reserve hugs for special occasions. (Mark Lennihan/The Associated Press)

If you were to give someone a special occasion hug, brief contact while wearing masks and with your faces turned away “would be the safest way to do it,” she said.

It might not be a bad idea to hold your breath as well, said CBC News medical contributor Dr. Peter Lin.

Hold your breath before “going in for the hug,” he told CBC News Network. “The virus is not moving at that point.” 

Lin said he even recommends this move to elderly grandparents.

“Once the hug is over, hold your breath again as they pull away, and the virus can’t be breathed into your system.”

That said, physical embraces aren’t without risk, and that might increase when the grandkids go back to school.

“Some people might say, ‘You know what. I’m still OK hugging my grandchildren,'” said Dr. Isaac Bogoch, infectious disease specialist at Toronto General Hospital.  

“Other people might say, ‘The risk is too high, and I’m not going to do this anymore, and we’ll get our hugs in before school starts,'” he said.

Bogoch advised keeping an eye on community transmission in your area. If rates go up, you may want to pump the brakes on close activity with the little ones. We looked at how grandparents might mitigate the back-to-school risks in a previous FAQ.

Health Canada approves updated Moderna COVID-19 vaccine

Published

 on

 

TORONTO – Health Canada has authorized Moderna’s updated COVID-19 vaccine that protects against currently circulating variants of the virus.

The mRNA vaccine, called Spikevax, has been reformulated to target the KP.2 subvariant of Omicron.

It will replace the previous version of the vaccine that was released a year ago, which targeted the XBB.1.5 subvariant of Omicron.

Health Canada recently asked provinces and territories to get rid of their older COVID-19 vaccines to ensure the most current vaccine will be used during this fall’s respiratory virus season.

Health Canada is also reviewing two other updated COVID-19 vaccines but has not yet authorized them.

They are Pfizer’s Comirnaty, which is also an mRNA vaccine, as well as Novavax’s protein-based vaccine.

These people say they got listeria after drinking recalled plant-based milks

Published

 on

 

TORONTO – Sanniah Jabeen holds a sonogram of the unborn baby she lost after contracting listeria last December. Beneath, it says “love at first sight.”

Jabeen says she believes she and her baby were poisoned by a listeria outbreak linked to some plant-based milks and wants answers. An investigation continues into the recall declared July 8 of several Silk and Great Value plant-based beverages.

“I don’t even have the words. I’m still processing that,” Jabeen says of her loss. She was 18 weeks pregnant when she went into preterm labour.

The first infection linked to the recall was traced back to August 2023. One year later on Aug. 12, 2024, the Public Health Agency of Canada said three people had died and 20 were infected.

The number of cases is likely much higher, says Lawrence Goodridge, Canada Research Chair in foodborne pathogen dynamics at the University of Guelph: “For every person known, generally speaking, there’s typically 20 to 25 or maybe 30 people that are unknown.”

The case count has remained unchanged over the last month, but the Public Health Agency of Canada says it won’t declare the outbreak over until early October because of listeria’s 70-day incubation period and the reporting delays that accompany it.

Danone Canada’s head of communications said in an email Wednesday that the company is still investigating the “root cause” of the outbreak, which has been linked to a production line at a Pickering, Ont., packaging facility.

Pregnant people, adults over 60, and those with weakened immune systems are most at risk of becoming sick with severe listeriosis. If the infection spreads to an unborn baby, Health Canada says it can cause miscarriage, stillbirth, premature birth or life-threatening illness in a newborn.

The Canadian Press spoke to 10 people, from the parents of a toddler to an 89-year-old senior, who say they became sick with listeria after drinking from cartons of plant-based milk stamped with the recalled product code. Here’s a look at some of their experiences.

Sanniah Jabeen, 32, Toronto

Jabeen says she regularly drank Silk oat and almond milk in smoothies while pregnant, and began vomiting seven times a day and shivering at night in December 2023. She had “the worst headache of (her) life” when she went to the emergency room on Dec. 15.

“I just wasn’t functioning like a normal human being,” Jabeen says.

Told she was dehydrated, Jabeen was given fluids and a blood test and sent home. Four days later, she returned to hospital.

“They told me that since you’re 18 weeks, there’s nothing you can do to save your baby,” says Jabeen, who moved to Toronto from Pakistan five years ago.

Jabeen later learned she had listeriosis and an autopsy revealed her baby was infected, too.

“It broke my heart to read that report because I was just imagining my baby drinking poisoned amniotic fluid inside of me. The womb is a place where your baby is supposed to be the safest,” Jabeen said.

Jabeen’s case is likely not included in PHAC’s count. Jabeen says she was called by Health Canada and asked what dairy and fresh produce she ate – foods more commonly associated with listeria – but not asked about plant-based beverages.

She’s pregnant again, and is due in several months. At first, she was scared to eat, not knowing what caused the infection during her last pregnancy.

“Ever since I learned about the almond, oat milk situation, I’ve been feeling a bit better knowing that it wasn’t something that I did. It was something else that caused it. It wasn’t my fault,” Jabeen said.

She’s since joined a proposed class action lawsuit launched by LPC Avocates against the manufacturers and sellers of Silk and Great Value plant-based beverages. The lawsuit has not yet been certified by a judge.

Natalie Grant and her seven year-old daughter, Bowmanville, Ont.

Natalie Grant says she was in a hospital waiting room when she saw a television news report about the recall. She wondered if the dark chocolate almond milk her daughter drank daily was contaminated.

She had brought the girl to hospital because she was vomiting every half hour, constantly on the toilet with diarrhea, and had severe pain in her abdomen.

“I’m definitely thinking that this is a pretty solid chance that she’s got listeria at this point because I knew she had all the symptoms,” Grant says of seeing the news report.

Once her daughter could hold fluids, they went home and Grant cross-checked the recalled product code – 7825 – with the one on her carton. They matched.

“I called the emerg and I said I’m pretty confident she’s been exposed,” Grant said. She was told to return to the hospital if her daughter’s symptoms worsened. An hour and a half later, her fever spiked, the vomiting returned, her face flushed and her energy plummeted.

Grant says they were sent to a hospital in Ajax, Ont. and stayed two weeks while her daughter received antibiotics four times a day until she was discharged July 23.

“Knowing that my little one was just so affected and how it affected us as a family alone, there’s a bitterness left behind,” Grant said. She’s also joined the proposed class action.

Thelma Feldman, 89, Toronto

Thelma Feldman says she regularly taught yoga to friends in her condo building before getting sickened by listeria on July 2. Now, she has a walker and her body aches. She has headaches and digestive problems.

“I’m kind of depressed,” she says.

“It’s caused me a lot of physical and emotional pain.”

Much of the early days of her illness are a blur. She knows she boarded an ambulance with profuse diarrhea on July 2 and spent five days at North York General Hospital. Afterwards, she remembers Health Canada officials entering her apartment and removing Silk almond milk from her fridge, and volunteers from a community organization giving her sponge baths.

“At my age, 89, I’m not a kid anymore and healing takes longer,” Feldman says.

“I don’t even feel like being with people. I just sit at home.”

Jasmine Jiles and three-year-old Max, Kahnawake Mohawk Territory, Que.

Jasmine Jiles says her three-year-old son Max came down with flu-like symptoms and cradled his ears in what she interpreted as a sign of pain, like the one pounding in her own head, around early July.

When Jiles heard about the recall soon after, she called Danone Canada, the plant-based milk manufacturer, to find out if their Silk coconut milk was in the contaminated batch. It was, she says.

“My son is very small, he’s very young, so I asked what we do in terms of overall monitoring and she said someone from the company would get in touch within 24 to 48 hours,” Jiles says from a First Nations reserve near Montreal.

“I never got a call back. I never got an email”

At home, her son’s fever broke after three days, but gas pains stuck with him, she says. It took a couple weeks for him to get back to normal.

“In hindsight, I should have taken him (to the hospital) but we just tried to see if we could nurse him at home because wait times are pretty extreme,” Jiles says, “and I don’t have child care at the moment.”

Joseph Desmond, 50, Sydney, N.S.

Joseph Desmond says he suffered a seizure and fell off his sofa on July 9. He went to the emergency room, where they ran an electroencephalogram (EEG) test, and then returned home. Within hours, he had a second seizure and went back to hospital.

His third seizure happened the next morning while walking to the nurse’s station.

In severe cases of listeriosis, bacteria can spread to the central nervous system and cause seizures, according to Health Canada.

“The last two months have really been a nightmare,” says Desmond, who has joined the proposed lawsuit.

When he returned home from the hospital, his daughter took a carton of Silk dark chocolate almond milk out of the fridge and asked if he had heard about the recall. By that point, Desmond says he was on his second two-litre carton after finishing the first in June.

“It was pretty scary. Terrifying. I honestly thought I was going to die.”

Cheryl McCombe, 63, Haliburton, Ont.

The morning after suffering a second episode of vomiting, feverish sweats and diarrhea in the middle of the night in early July, Cheryl McCombe scrolled through the news on her phone and came across the recall.

A few years earlier, McCombe says she started drinking plant-based milks because it seemed like a healthier choice to splash in her morning coffee. On June 30, she bought two cartons of Silk cashew almond milk.

“It was on the (recall) list. I thought, ‘Oh my God, I got listeria,’” McCombe says. She called her doctor’s office and visited an urgent care clinic hoping to get tested and confirm her suspicion, but she says, “I was basically shut down at the door.”

Public Health Ontario does not recommend listeria testing for infected individuals with mild symptoms unless they are at risk of developing severe illness, such as people who are immunocompromised, elderly, pregnant or newborn.

“No wonder they couldn’t connect the dots,” she adds, referencing that it took close to a year for public health officials to find the source of the outbreak.

“I am a woman in my 60s and sometimes these signs are of, you know, when you’re vomiting and things like that, it can be a sign in women of a bigger issue,” McCombe says. She was seeking confirmation that wasn’t the case.

Disappointed, with her stomach still feeling off, she says she decided to boost her gut health with probiotics. After a couple weeks she started to feel like herself.

But since then, McCombe says, “I’m back on Kawartha Dairy cream in my coffee.”

B.C. mayors seek ‘immediate action’ from federal government on mental health crisis

Published

 on

 

VANCOUVER – Mayors and other leaders from several British Columbia communities say the provincial and federal governments need to take “immediate action” to tackle mental health and public safety issues that have reached crisis levels.

Vancouver Mayor Ken Sim says it’s become “abundantly clear” that mental health and addiction issues and public safety have caused crises that are “gripping” Vancouver, and he and other politicians, First Nations leaders and law enforcement officials are pleading for federal and provincial help.

In a letter to Prime Minister Justin Trudeau and Premier David Eby, mayors say there are “three critical fronts” that require action including “mandatory care” for people with severe mental health and addiction issues.

The letter says senior governments also need to bring in “meaningful bail reform” for repeat offenders, and the federal government must improve policing at Metro Vancouver ports to stop illicit drugs from coming in and stolen vehicles from being exported.

Sim says the “current system” has failed British Columbians, and the number of people dealing with severe mental health and addiction issues due to lack of proper care has “reached a critical point.”

Vancouver Police Chief Adam Palmer says repeat violent offenders are too often released on bail due to a “revolving door of justice,” and a new approach is needed to deal with mentally ill people who “pose a serious and immediate danger to themselves and others.”
