Should Canadians be worried about polio? New viruses? Vaccination is key, says Tam – q107.com

With the polio virus making a comeback in some parts of the world, many Canadians may be wondering how to protect themselves against the disease. According to Canada’s top doctor, getting vaccinated is the best and most effective way to do so.

“When it comes to vaccine-preventable illnesses, the vaccine against polio is very effective,” said Dr. Theresa Tam, Canada’s chief public health officer, during a virtual health update on Friday.

“The key is to get up-to-date with your vaccination…The vaccine coverage is quite high for polio in Canada, but I don’t know what happened during the pandemic. I hope people are getting caught up before school or travel,” she added.

U.S. officials reported in early August that an unvaccinated American in New York, in Rockland County, north of the city was diagnosed with the country’s first case of polio in nearly a decade.

No other cases have been reported and the U.S. Centers for Disease Control (CDC) are urging parents to get their children vaccinated against the potentially deadly disease.

That discovery came shortly after British health authorities reported finding evidence that the virus has spread in London but no cases have been reported in people so far.

U.K.’s National Health Service says investigations into community transmission are ongoing and that children aged one to nine in London have been made eligible for booster doses of a polio vaccine as of Aug. 10.

Even though Health Canada has not recorded a case of the virus in more than 25 years, Dr. Tam explained during the health update that when it comes to vaccine-preventable illnesses, the issue is under immunization, which can often lead to cases re-emerging.

How does polio spread? What are the symptoms? Here’s what we know

Poliovirus is highly contagious and usually causes no symptoms or mild symptoms such as low-grade fever, malaise, nausea, diarrhea and sore throat. Illnesses are most common in infants and young children, but adults who are not fully immunized can also become sick. The virus attacks the nervous system, with one to five per cent of infections causing meningitis and less than one per cent resulting in paralysis.

People who are unvaccinated or incompletely vaccinated are at the greatest risk of paralysis from polio.

Canada’s routine childhood vaccine schedules include injectable polio vaccines before the age of two years and a booster at four to six years. The injectable form of the vaccine is inactivated and does not transmit the virus person-to-person.

Several experts on climate change and infectious disease have agreed that a warming planet will likely lead to increased risk for the emergence of new viruses.

In a new study published in the journal Nature Climate Change, researchers looked through the medical literature of established cases of illnesses and found that 218 out of the known 375 human infectious diseases, or 58 per cent, seemed to be made worse by one of 10 types of extreme weather connected to climate change.

These new and re-emerging infectious diseases include monkeypox, malaria, hantavirus, cholera, anthrax, and the Langya virus detected in China.

Tam too, highlighted the possibility of increased emergence of viruses caused by climate change.

Emerging infectious diseases that are mostly transmitted from animals to humans are expected to rise because of climate change and global travel, cautioned Tam. However, vaccination can help counter the transmission.

“We do need to prepare, do the research and not ignore them…Monkeypox as we know has been knocking on our doors for quite some time and has now found a way to get into the human population,” said Tam.

Monkeypox is primarily transmitted through prolonged close contact with an infected person and the majority of cases reported in the current outbreak involve men who had intimate sexual contact with other men, according to the WHO.

Monkeypox infections have also been found in rodents and other wild animals, which can spread the virus to humans, the World Health Organization (WHO) says.

In Canada, as of Aug. 19, 1,168 monkeypox cases have been reported across the country, with Ontario leading the case count with 571 infections, followed by Quebec with 453.

To date, there have been 30 hospitalizations, but no deaths in Canada.

“Vaccines have been researched and we have some of that, maybe not enough for the global need but at least all the research has been done prior,” said Tam.

As more infectious diseases emerge, she says global collaborations and more support is needed to look at the risks of re-emergence of viruses that may lead to the next pandemic.

Plans underway to monitor Canadian sewage for monkeypox, polio traces: Tam

In the meantime, plans are underway to sift through Canadian sewage to test for and measure new health threats like monkeypox and polio after the success this testing has achieved in detecting COVID-19, according to Tam.

Experts at the National Microbiology Lab have discovered a promising approach to detect monkeypox in wastewater and will use the infrastructure developed during the pandemic to look for it, she added.

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.
