The Public Health Agency of Canada (PHAC) says a resurgence of COVID-19 appears to be underway, fuelled by the highly transmissible Omicron variant. At the same time, most COVID restrictions have been lifted across the country, more adults are heading back to workplaces, and kids, for the most part, no longer have to wear masks in schools.

“As of March 31, daily average case counts have increased by 28 per cent nationally,” Canada’s Chief Public Health Officer Theresa Tam said during a briefing last week. 

It seems everyone either knows someone who is sick or they are sick themselves. Two of the doctors who spoke to CBC News for this story recently tested positive. 

But with limited access to PCR tests across Canada, some who are getting sick are wondering if they have COVID or a cold or the flu — and what they should do if they have COVID-like symptoms but don’t actually feel so unwell. 

We’ll answer some of those questions here.

Canada’s Chief Public Health Officer Theresa Tam says that whenever public health measures are relaxed, a resurgence of COVID-19 cases can be expected. Tam says she encourages people to continue wearing masks to keep the pandemic under control. 1:45

Is it COVID or just a cold? 

It’s impossible to know for sure whether you have COVID-19 without a test, said Dr. Shazma Mithani, an emergency physician in Edmonton. 

“There’s no specific symptom or lack of symptom that can say for sure it is COVID or not.”

The current list of possible Covid-19 symptoms in Canada is long – 14 in all. And PHAC warns that symptoms vary from one person to another, and that age can be a factor. 

Right now, some of the most commonly experienced symptoms of COVID-19 include:

  • sore throat
  • runny nose
  • sneezing
  • new or worsening cough
  • fatigue 
  • shortness of breath or difficulty breathing
  • temperature equal to or more than 38°C

“Many people who have COVID infection feel almost nothing or very mild symptoms — especially if they’re young and healthy — versus some people as they start to get into their 40s, 50s and upwards seem to be much more symptomatic,” said Dr. Lisa Barrett, an infectious disease doctor and researcher at Dalhousie University in Halifax.

And a once telltale sign has all but disappeared. 

“That loss of taste and smell, which was kind of a warning symptom of, like, this is very likely COVID … that has evolved out of the virus, where it’s less prominent now,” said Barrett. 

What doctors say they are seeing more of with Omicron is gastrointestinal symptoms, especially diarrhea, but also vomiting and abdominal pain. 

Still, the bottom line is that testing is the only way to know for sure whether you have COVID-19. 

If you have manageable symptoms, like a mild cold, should you still do a COVID-19 test? 

Doctors say yes. 

“The purpose of a rapid test is not to tell you you’re not infected,” said Barrett.

“The purpose of a rapid test at this point is to tell you, if you do have a positive, that it’s highly likely that you have Omicron, or COVID.”

And knowing that is important for several reasons. 

“If you’re a person at high risk, getting a test would make you eligible for antiviral treatment,” said Dr. Kashif Pirzada, an emergency physician in Toronto. 

He recommends anyone who is elderly, immunocompromised, or who has multiple medical conditions to get a rapid antigen test at the very least, though a PCR would be best. Still, he said a positive rapid test “would put you in line to get these new antiviral medications,” including Remdesivir or Paxlovid.

Rapid testing is also recommended if you are young or otherwise healthy, for a few reasons.

“In the case of a situation where somebody might be unfortunate enough to develop long COVID, it’s important to have that documentation of having had COVID,” said Mithani.

She said it’s also important to know so that you can let anyone you were in close contact with know that they’ve been exposed to the virus. 

I’ve heard rapid tests don’t work on Omicron, so what’s the use?  

It’s not entirely clear yet why the rapid tests don’t seem to pick up Omicron as effectively as they picked up earlier variants.

Barrett said it is too early to know whether it is the variant itself that is more difficult to pick up, or whether there is less viral load to detect because people getting sick have some level of immunity from vaccination or previous infection. 

But there are ways to make the test more effective. 

First, test more often.

“Testing every 24 hours while you’re symptomatic,” said Mithani.

“For at least for every single day that you’re symptomatic, I would test every day if you have access to that number of rapid tests. If not, then you can stretch it out every one to two, or one to three days, just to ration tests a little bit.”

Second, go beyond your nose.

“Swab both your throat and your nose to improve the sensitivity or the accuracy of the test,” said Mithani.

She advises swabbing your throat first, around where your tonsils are and where the uvula is in the middle.

“Swab it aggressively,” she said, “and then swab both of your nostrils.”

Pirzada said you can swab your cheek, too, in between doing your throat and nose.

That said, he points out some rapid tests have been found to perform better than others. And all of the doctors agreed that just because you test negative, that does not mean you don’t have COVID.

“As soon as you develop any cold-like symptoms, that’s a sign that you might have it,” said Pirzada.

“The rapid test, even if it’s negative, don’t take that as gospel, especially right now.”

Does the colour of nasal discharge indicate whether it is more likely COVID? 

No. Coloured mucus — green or yellow, and sometimes foul-smelling — often comes from a sinus infection, said Pirzada, which can be bacterial. But he said clear or coloured mucus will not tell you with any certainty whether it is COVID. You need to test. 

I don’t know anyone with the flu — is it still around? 

Influenza rates remain low for this time of year, according to PHAC’s FluWatch report. In fact, it says there has been “no evidence of community circulation of influenza” during the entire 2021-2022 season.

Despite doing similar numbers of lab tests for flu, the test positivity rate is “exceptionally low” across Canada, at 0.13 per cent, compared to an average of 23 per cent test positivity for the same period in the past six pre-pandemic seasons. 

This flu season (which began Aug. 29, 2021) has seen just 551 influenza detections reported, compared to an average of 38,193 by this point in the past six pre-pandemic flu seasons.

Mithani said doctors are seeing cases of influenza in Edmonton hospitals, and if someone high-risk comes in with symptoms and tests negative for COVID-19, they will be tested for influenza. It’s much the same in other provinces, too. 

Pirzada said anyone high risk in Ontario will also be tested for influenza if the COVID PCR test in hospital is negative. 

“So we are still testing for it, it’s just not coming back positive very often,” said Pirzada. 

“Some strains of flu have actually gone extinct since the pandemic started.”

Young children who present at hospital with COVID-like symptoms will also be tested for flu and other respiratory illnesses, including RSV. 

If people are masking and being careful, why are they still getting colds or flu? 

While COVID-19 is primarily airborne, colds and flu spread more on surfaces, too, so Pirzada said it’s possible people are catching them that way.

The other thing, he said, is children.

“Children are spreading these viruses with gusto with each other, and they’re bringing it home. And then you, if you have children, are spreading it to other people at your workplace.”

The best way to avoid colds and flu, in addition to continuing to wear a mask, is the age-old advice to wash your hands and not touch your face.

What’s the biggest misunderstanding about COVID-19 right now?

“The most dangerous one is that COVID living means pretending it’s not around,” said Barrett.   

“That if you are somebody who wants to live with COVID, that you have to forget about it and just do what you did before COVID — the same amount of interaction, the same type of interaction without a mask, no testing, no isolation. That is the dangerous misconception.”

Pirzada said it’s also important to remember that if you get COVID, it doesn’t mean you won’t get it again. 

“Even if if you get sick now … immunity to COVID is very short, so you could get sick in the next wave in two or three months.”

He said there needs to be a move to policies that cut down on the amount of circulating virus, “like good ventilation, masking in indoor spaces when there’s big waves like this, and the rapid tests.”

Mask mandates should be extended in Quebec, doctor says

Dr. Christopher Labos spoke with CBC News about the pandemic’s sixth wave in Quebec, and how he thinks it’s best for mask mandates to continue for the time being, to reduce the risk of hospitalizations. 6:01

“The most important thing is what I call the vaccine-plus plan,” said Barrett. 

“Which is get all the [vaccine] doses that you’re eligible to get. Wear a mask indoors — it’s not perfect, but it’s certainly helpful. And then, where available, test and isolate and keep your contact number moderate. You don’t have to stay home, but keeping it moderate.”

She said that if you do go out to a restaurant or other indoor gathering without wearing a mask, try to avoid seeing vulnerable people for three days after to make sure you don’t develop symptoms. And if you need to interact with someone who is high risk, distance, wear a mask and practise good hand hygiene.

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.”
