Zoos hiding birds as avian flu spreads in Canada and United States – The Globe and Mail

Zoos across North America are moving their birds indoors and away from people and wildlife as they try to protect them from the highly contagious and potentially deadly avian influenza.

Penguins may be the only birds visitors to many zoos can see right now, because they already are kept inside and usually protected behind glass in their exhibits, making it harder for the bird flu to reach them.

Nearly 23 million chickens and turkeys have already been killed across the United States to limit the spread of the virus, and zoos are working hard to prevent any of their birds from meeting the same fate. It would be especially upsetting for zoos to have to kill any of the endangered or threatened species in their care.

“It would be extremely devastating,” said Maria Franke, who is the manager of welfare science at Toronto Zoo, which has less than two dozen Loggerhead Shrike songbirds that it’s breeding with the hope of reintroducing them into the wild. “We take amazing care and the welfare and well being of our animals is the utmost importance. There’s a lot of staff that has close connections with the animals that they care for here at the zoo.”

Toronto Zoo workers are adding roofs to some outdoor bird exhibits and double-checking the mesh surrounding enclosures to ensure it will keep wild birds out.

Birds shed the virus through their droppings and nasal discharge. Experts say it can be spread through contaminated equipment, clothing, boots and vehicles carrying supplies. Research has shown that small birds that squeeze into zoo exhibits or buildings can also spread the flu, and that mice can even track it inside.

So far, no outbreaks have been reported at zoos, but there have been wild birds found dead that had the flu. For example, a wild duck that died in a behind-the-scenes area of the Blank Park Zoo in Des Moines, Iowa, after tornadoes last month tested positive, zoo spokesman Ryan Bickel said.

Most of the steps zoos are taking are designed to prevent contact between wild birds and zoo animals. In some places, officials are requiring employees to change into clean boots and don protective gear before entering bird areas.

When bird flu cases are found in poultry, officials order the entire flock to be killed because the virus is so contagious. However, the U.S. Department of Agriculture has indicated that zoos might be able to avoid that by isolating infected birds and possibly euthanizing a small number of them.

Sarah Woodhouse, director of animal health at Omaha’s Henry Doorly Zoo and Aquarium, said she is optimistic after talking with state and federal regulators.

“They all agree that ordering us to depopulate a large part of our collection would be the absolute last-ditch effort. So they’re really interested in working with us to see what we can do to make sure that we’re not going to spread the disease while also being able to take care of our birds and not have to euthanize,” Woodhouse said.

Among the precautions zoos are taking is to keep birds in smaller groups so that if a case is found, only a few would be affected. The USDA and state veterinarians would make the final decision about which birds had to be killed.

“Euthanasia is really the only way to keep it from spreading,” said Luis Padilla, who is vice president of animal collections at the Saint Louis Zoo. “That’s why we have so many of these very proactive measures in place.”

The National Aviary in Pittsburgh – the nation’s largest –- is providing individual health checks for each of its roughly 500 birds. Many already live in large glass enclosures or outdoor habitats where they don’t have direct exposure to wildlife, said Dr. Pilar Fish, the aviary’s senior director of veterinary medicine and zoological advancement.

Kansas City Zoo CEO Sean Putney said he’s heard a few complaints from visitors, but most people seem OK with not getting to see some birds. “I think our guests understand that we have what’s in the best interests of the animals in mind when we make these decisions even though they can’t get to see them,” Putney said.

Officials emphasize that bird flu doesn’t jeopardize the safety of meat or eggs or represent a significant risk to human health. No infected birds are allowed into the food supply, and properly cooking poultry and eggs kills bacteria and viruses. No human cases have been found in the U.S., according to the Centers for Disease Control and Prevention.

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.
