Anaplasmosis is a tick-borne disease that’s on the rise in Canada

Published

 on

Tick experts are warning Canadians to be on the lookout for symptoms of a tick-borne disease whose case counts have been steadily increasing over the past 15 years.

Anaplasmosis is an infection contracted by humans and animals caused by the Anaplasma phagocytophilum bacteria and spread by ticks.

In the early 2000s, provinces and territories began reporting a handful of human cases each year, but experts are now warning that they’re seeing up to 500 cases a year in the regions where anaplasma-carrying ticks live, although not all of those are necessarily full-blown clinical cases of the infection.

“It is kind of the new kid on the block,” said Heather Coatsworth, a research scientist for the Public Health Agency of Canada’s National Microbiology Laboratory in an interview with Dr. Brian Goldman, host of CBC’s The Dose.

Ticks carrying anaplasmosis are primarily found in Nova Scotia, Quebec and Ontario, though cases have been reported in Manitoba and Alberta.

Symptoms and transmission

Anaplasmosis is a disease caused by a bacterium that infects white blood cells in humans and animals.

Early symptoms include fever, chills, headache and fatigue. If left untreated, longer-term symptoms include respiratory failure, anemia, liver disease and death in severe cases.

“That’s primarily with immunocompromised people, as well as children and elderly,” Coatsworth said.

It takes about 18 hours for a tick to infect you with the anaplasma bacteria, says Heather Coatsworth, chief field studies research scientist at the Public Health Agency of Canada’s National Microbiology Laboratory. (Public Health Agency of Canada)

It takes roughly 18 hours of feeding for a tick to infect the host with the bacteria.

“Since it’s a blood-borne disease, it can also be transmitted by blood transfusion [and] solid organ donation,” said Coatsworth.

“And there is the hypothesis that it can be transmitted from mother to baby as well.”

The first case of anaplasmosis in a Canadian was reported in 2009.

How does anaplasmosis compare to Lyme disease?

Anaplasmosis shares common early symptoms with Lyme disease, including flu-like symptoms.

In fact, the same ticks that carry Lyme disease — typically black-legged and Western black-legged ticks — spread anaplasmosis by biting humans.

At times, researchers have encountered ticks co-infected with Lyme disease and anaplasmosis.

One major distinction between the symptoms of the two diseases is that anaplasmosis lacks the tell-tale bull’s eye rash that presents at the bite site of a tick carrying Lyme disease, according to Coatsworth.

However, the same antibiotic — doxycycline — can be used to treat both tick-borne illnesses.

Once treated for anaplasmosis, patients typically recover without post-treatment symptoms, such as arthritis, seen in some Lyme disease patients.

Lyme disease is still more common than anaplasmosis at this time, according to Coatsworth, with approximately 2,500 human cases in 2023, according to Health Canada.

Exact nation-wide statistics for anaplasmosis are currently unavailable, because it only became a nationally notifiable disease in April 2024, meaning cases now have to be reported to public health authorities.

Ontario is now tracking three additional tick-borne illnesses

 

A warming climate means a greater tick population and more tick-borne illnesses in Canada. Ontario already tracks cases of lyme disease, but starting now, it will also track three other tick-borne illnesses, including anaplasmosis, babesiosis and powassan virus disease.

How to prevent anaplasmosis

There’s no vaccine that prevents the transmission of anaplasmosis so avoiding bites is the best way to prevent any tick-borne disease.

“If you stop yourself from getting bitten by a tick or deal with a tick infection quickly and get the tick off, that’s going to help for anaplasmosis, Lyme disease … and any of the not fun diseases ticks transmit,” said Vett Lloyd, a biology professor at Mount Allison University who runs a tick lab.

Bug sprays such as DEET that specifically target ticks — rather than just mosquitos — are often most effective at preventing bites, Lloyd says.

Avoiding skin contact with grassy areas doing regular tick checks when in forested areas and while gardening or spending time in long grass can also reduce the risk.

“You’re looking for something that looks like a freckle, but unlike a freckle, [ticks have] legs,” said Lloyd.

If you do get bitten, tweezers are useful for removing ticks, Lloyd said. She recommends holding on to the tick in case it needs to be tested later.

When checking for ticks, ‘you’re looking for something that looks like a freckle,’ says Vett Lloyd, professor of biology at Mount Allison University in Sackville, N.B. (Submitted by Vett Lloyd)

Tucking socks over pants, wearing long sleeves and spraying clothes with the insecticide permethrin the night before going outside can help prevent tick bites, Coatsworth said.

Online tools such as eTick can help identify different tick species and high-risk areas.

 

Insect-borne infections on the rise thanks to climate change

 

Diseases carried by insects that infect humans, like Lyme disease and West Nile virus, are on the rise in Canada. The shorter, less severe winters due to climate change have allowed those insects to expand their range.

If you have been bitten, it’s impotant to keep an eye out for the sudden onset of flu-like symptoms, Coatsworth said.

“If you know you’ve been bitten by a tick, and then you’re suddenly getting flu-like symptoms a few days later, that’s a clue that you need to seek medical help sooner rather than later,” she said.

Still, Lloyd says Canadians shouldn’t let the fear of ticks prevent them from enjoying nature summer.

“Get outside, enjoy it and then do tick checks afterwards,” she said.

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.”
