Omicron's spread in B.C.: How much and how fast – Vancouver Is Awesome

Published

 on


The B.C. Centre for Disease Control is sequencing every positive COVID-19 case to determine the rate of Omicron’s spread in the province.

So far, the results are unsurprising: it’s spreading fast.

However, the exact number of cases of the latest variant in British Columbia is delayed by as much as seven to 11 days, as that’s how long the centre takes to sequence each specimen.

“There is a bit of a delay … the whole genome sequencing takes several days,” explained provincial health officer Dr. Bonnie Henry at her most recent press conference on Dec. 17.

“That’s one of the challenges we’re facing with this new variant around the world, is it takes time before you know when you can look back and look at what are we seeing,” said Henry.

On Dec. 17, the Ministry of Health announced 167 new “identified” cases of the COVID-19-causing variant that is showing significant resistance to the vaccines — particularly in terms of spreading the virus and presenting mild cold and flu symptoms. That’s more than double the total cases identified on Dec. 16: 135.

Henry announced the first case of the variant on Nov. 30. Omicron was first detected in South Africa, in a traveller from Nigeria.

The centre released its latest weekly Variant of Concern (VOC) report on Dec.17, which shows Omicron starting to gain traction on its rise to become the dominant variant, taking over from the Delta variant. However, the data is only complete to Dec. 4, so it provides little real-time context for the rapidly moving situation.

Typically, only a random sample of tests is used to find variants; however, the VOC report states: “To address the new Omicron …sequencing of all positives samples has resumed with retrospective specimens collected from November 15th 2021 onwards.”

To Dec. 4, the centre’s Public Health Laboratory (PHL) had performed sequencing on 103,605 positive specimens. Sequencing is used to investigate possible COVID-19 re-infections, track variants of concern and monitor vaccine effectiveness, according to the centre.

“The PHL’s COVID-19 genomics strategy acts like the proverbial canary in a coal mine, serving as an early warning signal that informs the laboratory and public health response. The increase in cases of the P.1 and B.1.1.7 variants in B.C. led to a change in the laboratory testing strategy to more rapidly identify and target outbreaks associated with variants of concern.”

However, the regular person will not be privy to what variant they have caught, according to a ministry spokesperson.

Where is Omicron spreading in B.C.?

According to the report, Omicron is spreading most extensively in the west side of the Lower Mainland (Vancouver Coastal Health) and on Vancouver Island. This fact aligns with the rapid rise in cases in both areas, Henry noted. Ninety-three of the 167 new Omicron cases announced Friday are in the Vancouver Coastal Health region.

“And as we have noted, [Omicron] has started causing a rapid increase in the number of new cases of COVID-19 that we’re seeing particularly in Vancouver Coastal and the Fraser Health region and here on Vancouver Island. It is moving quickly,” confirmed Henry.

Without real-time data, Henry said data from other jurisdictions as well as rising cases among vaccinated people is evidence enough of Omicron’s rise.  

“We know from Ontario, where they’ve been ahead of us, or from the U.K., that the reproductive number, when it’s introduced into the population, is higher than what we’re seeing with Delta over the last few weeks,” said Henry.

From Dec. 3 to 9, fully vaccinated people accounted for 45.1% of all 2,429 new cases in B.C. whereas from Dec. 9 to 15, fully vaccinated accounted for 57.2% of the 3,394 new cases. It is assumed, for now, the increases are a result of Omicron.

Notably, in this time, hospitalizations for fully vaccinated people remain stable: 1.1 for every 100,000 vaccinated people compared to 23.8 per 100,000 unvaccinated people.

While double doses of mRNA or viral vector vaccine are providing little relief to infections, pharmaceutical companies say a third shot, which is common for many established vaccines, can prove more effective.

Henry is delaying mass booster shots for all B.C. residents until January.

The province’s top doctor is also keeping most public spaces open with the exception of gatherings over 1,000 people, which must reduce their capacity by 50%.

She cited “unstructured social gatherings” as the main culprit for Omicron’s spread and has now ordered households to limit guests to a maximum of 10 people.

Henry’s also ordered clubs and restaurants to enforce a no table-hopping (mingling) rule as well as barring dancing. All organized sports tournaments are also cancelled but recreation leagues and gyms remain open. All venues require a vaccine passport.

Canada to donate up to 200,000 vaccine doses to combat mpox outbreaks in Africa

Published

 on

 

The Canadian government says it will donate up to 200,000 vaccine doses to fight the mpox outbreak in Congo and other African countries.

It says the donated doses of Imvamune will come from Canada’s existing supply and will not affect the country’s preparedness for mpox cases in this country.

Minister of Health Mark Holland says the donation “will help to protect those in the most affected regions of Africa and will help prevent further spread of the virus.”

Dr. Madhukar Pai, Canada research chair in epidemiology and global health, says although the donation is welcome, it is a very small portion of the estimated 10 million vaccine doses needed to control the outbreak.

Vaccine donations from wealthier countries have only recently started arriving in Africa, almost a month after the World Health Organization declared the mpox outbreak a public health emergency of international concern.

A few days after the declaration in August, Global Affairs Canada announced a contribution of $1 million for mpox surveillance, diagnostic tools, research and community awareness in Africa.

On Thursday, the Africa Centres for Disease Control and Prevention said mpox is still on the rise and that testing rates are “insufficient” across the continent.

Jason Kindrachuk, Canada research chair in emerging viruses at the University of Manitoba, said donating vaccines, in addition to supporting surveillance and diagnostic tests, is “massively important.”

But Kindrachuk, who has worked on the ground in Congo during the epidemic, also said that the international response to the mpox outbreak is “better late than never (but) better never late.”

“It would have been fantastic for us globally to not be in this position by having provided doses a much, much longer time prior than when we are,” he said, noting that the outbreak of clade I mpox in Congo started in early 2023.

Clade II mpox, endemic in regions of West Africa, came to the world’s attention even earlier — in 2022 — as that strain of virus spread to other countries, including Canada.

Two doses are recommended for mpox vaccination, so the donation may only benefit 100,000 people, Pai said.

Pai questioned whether Canada is contributing enough, as the federal government hasn’t said what percentage of its mpox vaccine stockpile it is donating.

“Small donations are simply not going to help end this crisis. We need to show greater solidarity and support,” he said in an email.

“That is the biggest lesson from the COVID-19 pandemic — our collective safety is tied with that of other nations.”

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
