A person in Louisiana has the first severe illness caused by bird flu in the U.S., health officials said Wednesday.
The patient had been in contact with sick and dead birds in backyard flocks, the U.S. Centers for Disease Control and Prevention (CDC) said. Agency officials didn’t immediately detail the person’s symptoms.
Previous illnesses in the U.S. had been mild and the vast majority had been among farm workers exposed to sick poultry or dairy cows.
Comments closedDecember 10, 2024 (British Columbia, Canada) – Advocacy groups in BC are calling on policy-makers to immediately reinstate healthcare mask requirements. The call comes as BC faces severe risks from COVID-19, a rise in “walking pneumonia,” local measles warnings, and Canada’s first human case of H5N1 avian influenza – which health officials warn could potentially turn into another pandemic.
Comments closedScientists from the Scripps Research Institute are reporting that it would take just a single mutation in the version of bird flu that has swept through U.S. dairy herds to produce a virus adept at latching on to human cells, a much simpler step than previously imagined.
To date, there have been no documented cases of one human passing avian influenza to another, the Scripps scientists wrote in their paper, which was published Thursday in the journal Science. The mutation they identified would allow the virus to attach to our cells by hitching itself to a protein on their surface, known as the receptor.
Comments closedA British Columbia teenager who got sick with bird flu two weeks ago did not infect any people or animals they were in contact with while infectious, according to provincial health officer Dr. Bonnie Henry.
The B.C. teenager was admitted to BC Children’s Hospital on Nov. 8 and remains in critical condition, although they have made some progress over the last few days and their care team is “hopeful that they will recover,” Henry said at a press conference Tuesday.
Because there have been no new cases and there are no new leads, the public health investigation will be closed for now, Henry said.
Comments closedThe teenager who is infected with the first human case of H5N1 avian influenza acquired in Canada remains in critical care at BC Children’s Hospital, officials said Tuesday.
Speaking at a news conference in Victoria, provincial health officer Dr. Bonnie Henry said the young person is stable, but still very sick and on a respirator.
Comments closedThe California Department of Public Health (CDPH) today said tests have identified a suspected avian flu infection in a child from Alameda County who had mild upper respiratory symptoms and no known contact with infected animals.
If confirmed, the case would mark the second avian flu infection in a child in North America from a yet undetermined source. Last week, health officials in Canada reported an H5N1 infection in a previously healthy British Columbia teen who is hospitalized in critical condition.
Comments closedThe 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.
Comments closedThe genetic sequence of the H5N1 bird flu virus that infected a teenager in British Columbia shows that the virus had undergone mutational changes that would make it easier for that version of H5N1 to infect people, scientists who have studied the data say.
There’s currently no evidence the teenager, who remains in critical condition in hospital, infected anyone else. If that’s the case, it is likely this mutated version of the virus would die out when the teen’s illness resolves. The source of the teen’s infection has not been determined, so it’s impossible to know for sure if the mutations were in the virus that infected him or her. But scientists think it is more likely that the mutations developed during the course of his or her infection.
Comments closedA Canadian teenager who is in critical condition after contracting H5N1 bird flu was infected with a version of the virus that is different from the one circulating in dairy cattle in the United States, Canadian authorities announced Wednesday.
The National Microbiology Laboratory in Winnipeg confirmed the infection was indeed caused by the H5N1 virus. But genetic sequencing showed that it is of a genotype that has been found in wild birds, not the version that has been circulating in dairy cattle in the U.S.
Comments closedFederal health officials have confirmed that a B.C. teen who is currently in hospital has Canada’s first human case of H5N1 avian flu.
Testing at the national microbiology labaratory in Winnipeg confirmed the case Wednesday, according to the Public Health Agency of Canada.
Comments closedCarolyn Law didn’t think much of it when a snow goose landed in her Richmond, B.C., backyard, on Halloween.
But hours later it had barely moved. Then it started bobbing its head repeatedly. About eight hours after she first saw the bird, it rolled over, began convulsing and died.
Comments closedA British Columbia (BC) teen from the Fraser Health region who was hospitalized with an earlier announced presumptive positive H5 avian flu infection is in critical condition, the province’s top health official said today.
In a media briefing streamed live on Canada’s Global News, Bonnie Henry, MD, BC’s health officer, shared the latest investigation findings, noting that the patient’s symptoms began on November 2, and he or she was seen that day at a hospital emergency room. She said initial symptoms included conjunctivitis, fever, and cough.
Comments closedB.C.’s provincial health officer says the teenager who has tested positive for bird flu is in critical condition in B.C. Children’s Hospital.
Dr. Bonnie Henry says the teenager, who has the first presumptive human case of bird flu contracted in Canada, was admitted to hospital late Friday. B.C. tests last week confirmed the teenager has the virus, but are waiting confirmation from a national laboratory in Winnipeg.
Comments closedBritish Columbia health officials are investigating what’s believed to be Canada’s first human case of avian influenza after a teenager tested presumptively positive for the disease, the Ministry of Health announced Saturday.
Comments closedB.C. health officials say they have detected Canada’s first-ever case of H5 avian influenza in a human.
In a news release Saturday afternoon, the office of the provincial health officer said a positive test for the H5 influenza virus was performed at the B.C. Centre for Disease Control’s public health laboratory.
Comments closedBC Conservative leader John Rustad assured anti-vaccine activists British Columbia would be open to joining other jurisdictions in legal proceedings inspired by the Nuremberg Trials that would be aimed at prosecuting those deemed responsible for COVID-19 public health measures and vaccines.
“Nuremberg 2.0,” an idea popular among COVID-19 conspiracy theorists and the online far-right, is simultaneously inspired by the Nuremberg Code, a set of ethical principles on human experimentation, as well as the Nuremberg Trials that prosecuted Nazi leaders after the Second World War.
Nuremberg 2.0 advocates typically call for those who created, justified or enforced public health measures — including politicians, doctors, academics, journalists and police — to be jailed and even executed for “crimes against humanity.”
Comments closedUpdated COVID-19 vaccines are starting to roll out to some high-risk Canadians, but others will have to wait a little while longer before these new shots are offered to them.
Last month, Health Canada approved Pfizer and Moderna’s latest COVID-19 vaccines targeting the most recent variants of the virus.
Both shots are approved for everyone aged six months and older.
The new mRNA vaccines from both pharmaceutical companies target the KP.2 subvariant of Omicron that was dominating COVID-19 spread earlier this year.
Comments closedThe prevalence of SARS-CoV-2 – the virus that causes COVID-19 – in B.C. wastewater is high and rising across most regions, according to the latest data from the B.C. Centre for Disease Control.
The BCCDC released its first weekly data update of the 2024-25 respiratory illness season Thursday, and took the opportunity to dramatically revise the information it presents and the way it is presented.
Gone is the previous year’s “COVID-19 Situation Report” dashboard, replaced with a new dashboard titled “Viral Respiratory Outcomes.”
While the situation report included specific numbers for newly confirmed infections, hospital admissions, critical care admissions and deaths within 30 days of a positive COVID test, the new dashboard reports the latter three numbers as a rate per million residents.
