Alberta invests $10M in serology testing to help track spread of COVID-19 – CBC.ca

Alberta is investing $10 million into targeted serology testing to help track the spread of COVID-19 across the province.

Serology testing is used to detect the presence of antibodies in a person’s blood, indicating that a person has been exposed to the COVID-19 virus in the past, Health Minister Tyler Shandro said Tuesday. 

“Serology testing is a big step forward, but we also need to be clear about what it doesn’t do,” Shandro said. “It does not, and I repeat not, replace swab testing.

“It doesn’t tell us if you’re currently sick or if you’re contagious, and it doesn’t tell us if you’re immune to COVID-19 or to a degree or for how long.”

Alberta Health is investing in four voluntary public health studies, he said.

Each will test specific groups of Albertans for the virus. Alberta Health Services will also make serology testing available for specific clinical purposes where testing can inform treatment decisions.

“This virus is new and we just don’t know how it behaves yet,” Shandro said. “We can make assumptions based on other viruses, and they may turn out to be right, but we can’t base our relaunch on assumptions.

“We need to know how much immunity people have after they’ve been infected, if they can be infected again.”

The tests will help epidemiologists understand what proportion of a population may have been exposed to COVID-19 within the past several months and then use that information to understand what proportion may not have been captured by swab testing, Dr. Deena Hinshaw, Alberta’s chief medical officer of health, told Tuesday’s news conference.

“Serology is not a useful individual clinical test except in some very rare select circumstances,” Hinshaw said. 

“I know that there are many individuals who are very curious about their own personal results.

“However, if we recruited only individuals who thought they might have had COVID we would get a non-representative sample of the population which wouldn’t be helpful for us to determine at an overall population level who may have been exposed.”

So far provincial labs have completed 402,837 swab tests for COVID-19.

Alberta is the first province in Canada to make targeted serology testing available, Shandro said.

Latest numbers

Alberta recorded 45 new cases of COVID-19 on Tuesday with no new deaths.

The number of active cases in the province now stands at 532. The number of deaths remains at 153. 

Thirty-seven people are in hospital, six of them in intensive care.

Another hospital has been hit by an outbreak, this time Edmonton’s Misericordia Community Hospital.

“This outbreak is confined to a single unit and so far six patients and two staff have tested positive,” Hinshaw said.

“Outbreak protocols have already been implemented, and all staff and patients who may have been exposed are being tested.”

‘We will continue to see some new cases’

Hinshaw also addressed the five restaurants in Edmonton that voluntarily closed for a short time when a staff member or customer reported testing positive for the disease.

Several Edmonton restaurants recently closed after employees or customers at these locations tested positive for COVID-19. On Tuesday, Dr. Deena Hinshaw, Alberta’s chief medical officer of health, said the province didn’t force these closures and that COVID-19 outbreaks haven’t been found in these restaurants. 2:01

“As we move forward, we will continue to see some new cases in all sectors, including the food-service industry,” she said. 

While it’s important to take every case seriously, one positive case does not automatically require a business to close for public health reasons, Hinshaw said.

“It also does not mean that everyone who visited the same establishment is automatically at risk. Determining who is at risk is something that our contact tracing teams closely assess based on when the individual became symptomatic.”

Hinshaw said she hasn’t yet heard of a similar situation in Calgary.

The city of Edmonton proper has 223 active cases, outpacing Calgary, which has 202. 

Here is how active cases across the province break down by zone:

  • Edmonton zone: 236 
  • Calgary zone: 230
  • North zone: 36
  • South zone: 22
  • Central zone: 3
  • Unknown: 5

Edmonton’s northeast region is now under a watch designation as it has more than 10 active cases and has surpassed 50 active cases per 100,000 people.

The watch went into effect Monday. The region has 45 active cases and an active case rate of 50.6.

The designation means the province is monitoring the risk and discussing with local government the possible need for additional health measures.

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.
