Canada to start testing some wastewater for polio 'as soon as possible' – CBC News

Published

 on


After new reports of polio cases abroad, and virus samples in the wastewater of several other developed countries, Canada intends to start testing wastewater from a number of cities “as soon as possible,” CBC News has learned.

The Public Health Agency of Canada (PHAC) already works to monitor polio activity around the world, a spokesperson said in an email response to CBC News questions.

Currently, PHAC’s National Microbiology Laboratory in Winnipeg does have the diagnostic tools available to test samples for poliovirus. Any suspected positive Canadian samples of poliovirus will be sent to that lab for further laboratory analysis and confirmation, with results shared with the respective local health authorities “so appropriate public health measures can be taken if necessary.”

According to the statement, PHAC has been communicating with national and international partners who are experts in this field to finalize a wastewater testing strategy. It will be testing wastewater samples that were collected earlier this year from “key high-risk municipalities” to determine if polio was present prior to the reported international cases.

The agency is not yet sharing which cities or municipalities are involved, a spokesperson said.

However, Eric Arts, a professor at Western University’s Schulich School of Medicine and Dentistry who is involved with Ontario’s wastewater surveillance initiative, said the province is among the areas engaged in discussions around wastewater testing for polio, as well as monkeypox, which has been spreading globally for months.

“We need to start surveying for a lot of these infectious diseases in our wastewater,” Arts said.

100s could be infected with polio in New York, health officials say

A health official in New York State says hundreds of people could be infected with the polio virus.

Samples will be sent to U.S. for additional confirmation

In terms of polio surveillance, PHAC will also be sending samples to the U.S. Centers for Disease Control and Prevention for additional confirmation.

“However, it is important to acknowledge that accurately testing wastewater for poliovirus is a developing science,” the agency’s statement continued. “For example, wastewater detections can be affected by extreme precipitation events, such as flooding in a community.”

Arts said identifying actual poliovirus in water can also be challenging due to a type of polio vaccine used in certain countries — a modified form of the virus which is delivered by mouth.

The vaccine can’t cause illness, but can be shed in human waste which winds up in sewer systems, and in some instances may evolve back into a form of the virus that could lead to disease. Typically, though, any samples would simply be catching vaccine-derived polio, not a harmful pathogen.

“It’s sometimes hard to determine what is actual poliovirus circulating versus the oral polio vaccine that’s circulating,” said Arts, who added it may show up in Canadian wastewater through individuals who’ve moved from countries where they were given the oral vaccine.

“It doesn’t mean there’s circulating polio in our population,” he said.

Reports of polio in U.S., U.K., Israel

But instances of polio infections have been reported this year in other countries where the virus isn’t typically found.

On Wednesday, British health authorities announced they will offer a polio booster dose to children aged one to nine in London, after finding evidence the virus has been spreading in multiple regions of the capital.

The agency said it was working closely with health authorities in the U.S. and Israel, as well as the World Health Organization, to investigate the links between polio viruses detected in those two countries. 

In July, Israel announced a recent outbreak of polio infections appeared to be under control, after multiple people became infected, including a Jerusalem girl who was paralyzed and now requires rehabilitation, according to the Jerusalem Post.

More recently, in the state of New York, one unvaccinated young adult suffered paralysis after a polio infection in Rockland County — an area known for low vaccination rates — which marked the first case reported in the U.S. in nearly a decade. 

Outbreaks also remain common in Afghanistan, Pakistan, and parts of Africa — areas of the world where vaccination efforts have not yet eradicated the virus.

Polio can often be asymptomatic, but in some cases, the viral infection can lead to paralysis or death.

RCMP end latest N.B. search regarding teenage girl who went missing in 2021

Published

 on

 

BATHURST, N.B. – RCMP in New Brunswick say a weekend ground search for evidence related to the disappearance of a teenage girl in 2021 didn’t reveal any new information.

In an emailed statement, the RCMP said 20 people participated in the search for evidence in the case of Madison Roy-Boudreau of Bathurst.

The release said the search occurred in the Middle River area, just south of the girl’s hometown.

Police have said the 14-year-old’s disappearance is being treated as a homicide investigation.

The RCMP said the search “did not reveal any new information regarding the circumstances of her disappearance.”

There are no plans for another search until police receive a tip or a lead pointing to a new search area.

Man Tasered after trespassing in Victoria school, forcing lockdown

Published

VICTORIA – A middle school in Victoria was forced into a lockdown after a man entered the building without permission, and police say they had to use a stun gun to make an arrest.

Victoria police say officers received multiple calls around noon on Monday of an unknown male entering Central Middle School, leading staff to set off emergency procedures that put the building under lockdown.

Police say its emergency response team arrived within minutes and found the suspect, who “appeared to be in a drug-induced state,” in the school’s library.

A statement from police says the suspect resisted arrest, and officers had to use a Taser to subdue the man.

He’s being held by police and has been assessed by emergency medical staff.

Police say the man was not armed and there were no continuing safety concerns for students and staff following the arrest.

B.C. Greens’ ex- leader Weaver thinks minority deal with NDP less likely than in 2017

Published

 on

 

VANCOUVER – Former B.C. Green leader Andrew Weaver knows what it’s like to form a minority government with the NDP, but says such a deal to create the province’s next administration is less likely this time than seven years ago.

Weaver struck a power-sharing agreement that resulted in John Horgan’s NDP minority government in 2017, but said in an interview Monday there is now more animosity between the two parties.

Neither the NDP nor the B.C. Conservatives secured a majority in Saturday’s election, raising the prospect of a minority NDP government if Leader David Eby can get the support of two Green legislators.

Manual recounts in two ridings could also play an important role in the outcome, which will not be known for about a week.

Weaver, who is no longer a member of the Greens, endorsed a Conservative candidate in his home riding.

He said Eby would be in a better position to negotiate if Furstenau, who lost her seat, stepped aside as party leader.

“I think Mr. Eby would be able to have fresh discussions with fresh new faces around the table, (after) four years of political sniping … between Sonia and the NDP in the B.C. legislature,” he said.

He said Furstenau’s loss put the two elected Greens in an awkward position because parties “need the leader in the legislature.”

Furstenau could resign as leader or one of the elected Greens could step down and let her run in a byelection in their riding, he said.

“They need to resolve that issue sooner rather than later,” he said.

The Green victories went to Rob Botterell in Saanich North and the Islands and Jeremy Valeriote in West Vancouver-Sea to Sky.

Neither Botterell nor Valeriote have held seats in the legislature before, Weaver noted.

“It’s not like in 2017 when, you know, I had been in the (legislature) for four years already,” Weaver said, adding that “the learning curve is steep.”

Sanjay Jeram, chair of undergraduate studies in political science at Simon Fraser University, said he doesn’t think it’ll be an “easygoing relationship between (the NDP and Greens) this time around.”

“I don’t know if Eby and Furstenau have the same relationship — or the potential to have the same relationship — as Horgan and Weaver did,” he said. “I think their demands will be a little more strict and it’ll be a little more of a cold alliance than it was in 2017 if they do form an alliance.”

Horgan and Weaver shook hands on a confidence-and-supply agreement before attending a rugby match, where they were spotted sitting together before the deal became public knowledge.

Eby said in his election-night speech that he had already reached out to Furstenau and suggested common “progressive values” between their parties.

Furstenau said in her concession speech that her party was poised to play a “pivotal role” in the legislature.

Botterell said in an election-night interview that he was “totally supportive of Sonia” and he would “do everything I can to support her and the path forward that she chooses to take because that’s her decision.”

The Green Party of Canada issued a news release Monday, congratulating the candidates on their victories, noting Valeriote’s win is the first time that a Green MLA has been elected outside of Vancouver Island.

“Now, like all British Columbians we await the final seat count to know which party will have the best chance to form government. Let’s hope that the Green caucus has a pivotal role,” the release said, echoing Furstenau’s turn of phrase.

The final results of the election won’t be known until at least next week.

Elections BC says manual recounts will be held on Oct. 26 to 28 in two ridings where NDP candidates led B.C. Conservatives by fewer than 100 votes after the initial count ended on Sunday.

The outcomes in Surrey City Centre and Juan de Fuca-Malahat could determine who forms government.

The election’s initial results have the NDP elected or leading in 46 ridings, and the B.C. Conservatives in 45, both short of the 47 majority mark in B.C.’s 93-seat legislature.

If the Conservatives win both of the recount ridings and win all other ridings where they lead, Rustad will win with a one-seat majority.

If the NDP holds onto at least one of the ridings where there are recounts, wins the other races it leads, and strikes a deal with the Greens, they would have enough numbers to form a minority government.

But another election could also be on the cards, since the winner will have to nominate a Speaker, reducing the government’s numbers in the legislature by one vote.

Elections BC says it will also be counting about 49,000 absentee and mail-in ballots from Oct. 26 to 28.

The NDP went into the election with 55 ridings, representing a comfortable majority in what was then an 87-seat legislature.

Jeram, with Simon Fraser University, said though the counts aren’t finalized, the Conservatives were the big winners in the election.

“They weren’t really a not much of a formal party until not that long ago, and to go from two per cent of the vote to winning 45 or more seats in the B.C. provincial election is just incredible,” he said in an interview Monday.

Jeram said people had expected Eby to call an election after he took over from John Horgan in 2022, and if he had, he doesn’t think there would have been the same result.

He said the B.C. Conservative’s popularity grew as a result of the decision of the BC Liberals to rebrand as BC United and later drop out.

“Had Eby called an election before that really shook out, and maybe especially before (Pierre) Poilievre, kind of really had the wind in his sails and started to grow, I think he could have won the majority for sure.”

He said he wasn’t surprised by the results of the election, saying polls were fairly accurate.

“Ultimately, it really was a result that we saw coming for a while, since the moment that BC United withdrew and put their support behind the conservatives, I think this was the outcome that was expected.”
