Manitoba looking to improve COVID-19 variant screening – CTV Edmonton

Published

 on


WINNIPEG —
Manitoba is looking into the steps involved in discovering and confirming COVID-19 variant cases in the province, after 18 days passed between the initial positive test to when the case of the B117 variant, which was first observed in the United Kingdom, was reported to the public.

The traveller arrived in Winnipeg on January 19th.

The province said in the bulletin reporting the case that on January 22, the initial test results from the traveller were received and the sample was sent to the National Microbiology Laboratory for DNA sequencing.

A spokesperson for the National Microbiology Lab told CTV News that it didn’t receive the sample until February 4. Two of the four days the sample was processed on fell on a weekend, and the results were known on February 8. The variant case was reported to the public on Feb. 9.

On Friday, Dr. Brent Roussin, Manitoba’s Chief Provincial Public Health Officer, said the whole process from sample collection to transport is being looked at.

“Just like any of our ongoing quality improvement that we do continually, we’ll look at all those factors,” said Dr. Roussin.

Roussin also said the province has since added the ability to screen for variants of concern at Cadham Provincial Lab, and the initial goal is to have that process complete within 48 hours of receiving a sample.

University of Manitoba biological sciences professor Jeffrey Marcus said in his experience, genetic sequencing can take six days to two weeks – depending on if the samples need to be transported to a different lab.

He said would expect better when dealing with a highly contagious virus.

“You would expect that everybody would be particularly diligent and do everything that they can to remove all the delays from the system,” Marcus said.

However, Marcus’ greater concern is the province isn’t tapping to the expertise and equipment available on university and college campuses to scale up the screening and sequencing abilities.

“It’s unfortunate, we have this sort of war on COVID and we are not treating it like a war,” he said. “We are not marshalling all (of) our resources we have available to achieve our goals.”

A part of this pattern, he said, is the 18 days it took to screen, sequence and report the first B117 variant case in the province. He said nothing involved with sequencing genetic material should take that long.

He also said Cadham Lab and the National Microbiology Lab are less than one block apart, so transport should not be a big issue.

“Which leads me to believe it was sitting in a freezer for about a week,” he said. 

Right now in Manitoba, about five per cent of screened samples are being sequenced for the three known variants of concern and the province is planning to do more.

When asked if the province would partner with universities or colleges, Roussin said that the Canadian COVID-19 Genomic Network has been up and running for quite some time.

“It is at par with any place in the world with the sequencing it does,” Roussin explained. “It’s a collaboration throughout the world, so the province has that expertise, and that expertise has been utilized.”

Roussin also noted the traveller in this first B117 case was returning from international travel.

“They had to isolate for 10 days,” he said. “And so that was done, it was done appropriately in this case, and we haven’t seen secondary transmission of it.”

Roussin said all of the close contacts for the case have since been tested twice; none have come back positive.

Quebec successfully pushes back against rise in measles cases – CBC.ca

Published

 on


Quebec appears to be winning its battle against the rising tide of measles after 45 cases were confirmed province-wide this year.

“We’ve had no locally transmitted measles cases since March 25, so that’s good news,” said Dr. Paul Le Guerrier, responsible for immunization for Montreal Public Health.

There are 17 patients with measles in Quebec currently, and the most recent case is somebody who was infected while abroad, he said.

But it was no small task to get to this point. 

Le Guerrier said once local transmission was detected, news was spread fast among health centres to ensure proper protocols were followed — such as not letting potentially infected people sit in waiting rooms for hours on end.

Then about 90 staffers were put to work, tracking down those who were in contact with positive cases and are not properly vaccinated. They were given post-exposure prophylaxis, which prevents disease, said Le Guerrier.

From there, a vaccination campaign was launched, especially in daycares, schools and neighbourhoods with low inoculation rates. There was an effort to convince parents to get their children vaccinated.

Vaccination in schools boosted

Some schools, mostly in Montreal, had vaccination rates as low as 30 or 40 per cent.

“Vaccination was well accepted and parents responded well,” said Le Guerrier. “Some schools went from very low to as high as 85 to 90 per cent vaccination coverage.”

But it’s not only children who aren’t properly vaccinated. Le Guerrier said people need two doses after age one to be fully inoculated, and he encouraged people to check their status.

There are all kinds of reasons why people aren’t vaccinated, but it’s only about five per cent who are against immunization, he said. So far, some 10,000 people have been vaccinated against measles province-wide during this campaign, Le Guerrier said. 

The next step is to continue pushing for further vaccination, but he said, small outbreaks are likely in the future as measles is spreading abroad and travellers are likely to bring it back with them.

Need to improve vaccination rate, expert says

Dr. Donald Vinh, an infectious diseases specialist from the McGill University Health Centre, said it’s not time to rest on our laurels, but this is a good indication that public health is able to take action quickly and that people are willing to listen to health recommendations.

“We are not seeing new cases or at least the new cases are not exceeding the number of cases that we can handle,” said Vinh.

“So these are all reassuring signs, but I don’t think it’s a sign that we need to become complacent.”

Vinh said there are also signs that the public is lagging in vaccine coverage and it’s important to respond to this with improved education and access. Otherwise, microbes capitalize on our weaknesses, he said. 

Getting vaccination coverage up to an adequate level is necessary, Vinh said, or more small outbreaks like this will continue to happen.

“And it’s very possible that we may not be able to get one under control if we don’t react quickly enough,” he said.

Pregnant women in the Black Country urged to get whooping cough vaccine – BBC.com

Pregnant women urged to get whooping cough vaccine

Babies are routinely given the vaccine at eight, 12 and 16 weeks

Pregnant women in the Black Country are being urged to get vaccinated against whooping cough after a rise in cases.

The bacterial infection of the lungs spreads very easily and can cause serious problems, especially in babies and young children.

The Black Country Integrated Care Board (ICB) is advising pregnant women between 16 and 32 weeks to contact their GP to get the vaccine so their baby has protection from birth.

The UK Health Security Agency warned earlier this year of a steady decline in uptake of the vaccine in pregnant women and children.

Symptoms of the infection, also known as “100-day cough”, are similar to a cold, with a runny nose and sore throat.

Sally Roberts, chief nursing officer for the ICB, which covers Wolverhampton, Dudley, Walsall and Sandwell, said anyone could catch it, but it was more serious for young children and babies.

“Getting vaccinated while you’re pregnant is highly effective in protecting your baby from developing whooping cough in the first few weeks of their life – ideally from 16 weeks up to 32 weeks of pregnancy,” she said.

“If for any reason you miss having the vaccine, you can still have it up until you go into labour.”

Measles cases stabilize in Montreal – CityNews Montreal

Published

 on


The number of measles cases has stabilized, according to the Montreal Public Health.

Since March 25, there have been no contaminations reported within the community.

“Our teams have identified all contact cases of measles,” said media relations advisor Geneviève Paradis. “It’s a laborious task: each measles case produces hundreds of contacts.”

All community transmission cases since February 2024 have been caused by returning travelers who were either unvaccinated or partially vaccinated.

Currently, there are 18 measles cases in Montreal – with 46 total in Quebec. This according to the April 18 figures from the provincial government.

“With the summer vacations approaching, if you’re travelling, it is essential to check if you are protected against measles,” explained Paradis.

According to Montreal Public Health, a person needs to have received two doses after the age of 12 months to be immunized against the virus.

They’ve launched a vaccination campaign throughout the region, and currently, 11,341 people have been vaccinated against measles in Montreal between March 19 and April 15.

Vaccination is also being provided in schools and at local service points.

“The vaccination operation is under the responsibility of the five CIUSSS of the territory,” concluded Paradis.
