Bird flu in Canada may have mutated to become more transmissible to humans

The teenager hospitalized with bird flu in British Columbia, Canada, may have a variation of the virus that has a mutation making it more transmissible among people, early data shows – a warning of what the virus can do that is especially worrisome in countries such as the US where some H5N1 cases are not being detected.

The US “absolutely” is not testing and monitoring bird flu cases enough, which means scientists could miss mutated cases like these, said Richard Webby, a virologist at St Jude children’s research hospital’s department of infectious diseases.

Wastewater testing for avian influenza to begin in some Ontario communities

As bird flu infections continue to rise among livestock and humans in the United States, surveillance is ramping up in Canada.

Wastewater testing for the H5N1 bird flu virus is set to begin in the coming weeks in Ontario communities considered at high risk, said Rob Delatolla, whose University of Ottawa lab will lead the wastewater surveillance as part of a research program based at the University of Guelph. That will likely mean testing wastewater in communities in agricultural regions of the province. It is unclear whether there will also be testing in larger cities.

A spike in COVID deaths has driven a decline in Australian life expectancy for the second year running

Australian life expectancy has gone backwards for the second year straight after a surge in COVID-19 deaths in 2022.

An Australian girl born today is expected to live to 85.1 years, and a boy to 81.1 years.

Australians still have the fourth-highest life expectancy in the world after Japanese, Swiss and Koreans.

The risk of long COVID reaches 37% after three infections, according to the INSPQ

As COVID-19 continues to circulate widely, a report from the INSPQ warns that the risk of getting long COVID increases with each reinfection, and notes that the Quebec health system is failing to help the growing number of people who have had persistent symptoms for months or even years.

The report by the Institut national de la santé publique du Québec (INSPQ), which surveyed thousands of health workers in Quebec who were infected between the beginning of the pandemic and summer 2023, was released quietly on Monday. Yet, this report warns that post COVID-19 condition, commonly known as long COVID, is affecting more and more people.

« This is an important and real issue. We want to raise awareness among the public and public health authorities,” says Sara Carazo, one of the authors of the report.

‘Long COVID has really mystified’: Western University researchers take steps to unravel long COVID mysteries

Long COVID can have wide-ranging impacts, but is most commonly associated with brain fog, breathing difficulties and debilitating fatigue.

“Long COVID has really mystified a lot of physicians and scientists,” according to Dr. Douglas Fraser. Fraser is a researcher with Western University’s Schulich School of Medicine and Dentistry, based in London, Ont.

H5N1 avian flu isolate from dairy worker is transmissible, lethal in animals

In experiments designed to learn more about the threat from the H5N1 avian flu virus spreading from cows to people, researchers found that an isolate from a sick dairy worker may be capable of replicating in human airway cells, is pathogenic in mice and ferrets, and can transmit among ferrets by respiratory droplets.

The team, based at the University of Wisconsin at Madison and Japan, reported its findings today in Nature. Working in a high-containment lab, the researchers used an H5N1 isolate grown from the eye of a dairy worker who had experienced conjunctivitis after exposure to infected cows.

‘Do no harm’ is hurting 400 million long Covid patients worldwide

Imagine, for a moment, that you wake up one morning with a debilitating illness that won’t let go. Weeks and months pass, but the crushing fatigue, constant headaches, and aching muscles remain. You can’t think straight. Simply showering or doing the dishes leaves you floored for days at a time, and the unpredictable symptoms — shortness of breath, dizziness, a racing heart — ebb and flow without warning. You find your life as you knew it slipping away.

This is life with long Covid: a condition that transforms the familiar rhythms of daily life into a living nightmare and constant battle for energy and clarity. But what happens when the only hope of lessening its severity becomes an issue of equity?

We are two of the more than 400 million people worldwide who have experienced long Covid. While we are both over four years into this illness, there is still not a single FDA-approved treatment for this devastating condition. Given the slow pace of research and development, there is unlikely to be proven treatment for years — possibly decades.

Long COVID patients suffer high rate of autonomic disorders, researchers say

Medical researchers at the University of Calgary say a condition affecting autonomic bodily processes — those that occur automatically, such as heart rate, bladder function and sweating — is frequently found in people diagnosed with long COVID.

The condition is known as dysautonomia, an umbrella term for a group of related conditions. Support networks for those who suffer from it are working to raise awareness throughout October, which has been deemed Dysautonomia Awareness Month by the advocacy group, Dysautonomia International.

Long COVID Is Harming Too Many Kids

Since the COVID pandemic began, claims that the disease poses only minimal risk to children have spread widely, on the presumption that the lower rate of severe acute illness in kids tells the whole story. Notions that children are nearly immune to COVID and don’t need to be vaccinated have pervaded.

These ideas are wrong. People making such claims ignore the accumulating risk of long COVID, the constellation of long-term health effects caused by infection, in children who may get infected once or twice a year. The condition may already have affected nearly six million kids in the U.S. Children need us to wake up to this serious threat. If we do, we can help our kids with a few straightforward and effective measures.

Covid-19 may increase the risk of heart attacks, strokes and deaths for three years after an infection, study suggests

Covid-19 could be a powerful risk factor for heart attacks and strokes for as long as three years after an infection, a large new study suggests.

The study was published Wednesday in the medical journal Atherosclerosis, Thrombosis, and Vascular Biology. It relied on medical records from roughly a quarter of a million people who were enrolled in a large database called the UK Biobank.

Ultra-powered MRI scans show damage to brain’s ‘control centre’ is behind long-lasting Covid-19 symptoms

Damage to the brainstem – the brain’s ‘control centre’ – is behind long-lasting physical and psychiatric effects of severe Covid-19 infection, a study suggests.

Using ultra-high-resolution scanners that can see the living brain in fine detail, researchers from the Universities of Cambridge and Oxford were able to observe the damaging effects Covid-19 can have on the brain.

The study team scanned the brains of 30 people who had been admitted to hospital with severe Covid-19 early in the pandemic, before vaccines were available. The researchers found that Covid-19 infection damages the region of the brainstem associated with breathlessness, fatigue and anxiety.

London clinical trial targets lingering COVID toll on patients – smell distortion

Haunted for more than a year by phantom smells she couldn’t explain, Rebecca Bruzzese said she worried about her safety and mental health.

She could smell burning cigarettes in her living room, but no one was smoking. Beef frying on the stove smelled like “excrement in a pan.” Coffee was even worse.

“It smelled like hot garbage,” the 32-year-old said.

Unable to eat, Bruzzese lost 30 pounds and developed other health problems.

Ottawa’s wastewater surveillance program extended for another year

Two months after the Ontario government pulled the plug on wastewater surveillance, Ottawa health and research institutions have teamed up to extend the program in the city for a least another year.

Calling it an innovative solution that allowed for better monitoring of COVID-19 in the community, CHEO, the CHEO Research Institute, the University of Ottawa and Ottawa Public Health announced an extension of wastewater surveillance on Friday.

In addition to monitoring COVID-19 levels in wastewater, the program monitors levels of influenza, RSV and mpox in Ottawa. The program has been extended until September 2025.
