Canadian health officials are investigating the first confirmed human case of bird flu in the country, marking a rare event as a teenager battles the virus. Despite its low transmission risk, experts warn of potential mutations due to ongoing outbreaks in livestock.

In an alarming development, a teenager in British Columbia is hospitalized in critical condition from H5N1, raising concerns about avian influenza transmission.
In a troubling incident, a teenager in British Columbia has been hospitalized in critical condition after contracting bird flu, marking Canada’s first confirmed human case of the virus's transmission. The health inquiry initiated on Tuesday aims to unpack the circumstances surrounding the infection, especially since the adolescent has no known ties to poultry farms—traditional hotspots for the avian influenza virus.
The strain in question, known as H5N1, is considered low-risk for public health due to its limited human-to-human transmissibility. Yet, experts are keeping a vigilant watch, as continued outbreaks in U.S. dairy cattle could heighten the risk of the virus mutating and potentially spreading more easily.
According to the Centers for Disease Control and Prevention, 46 cases of H5N1 have been documented in the United States, predominantly among farm workers, with most experiencing mild symptoms. Health authorities in British Columbia have tested 36 individuals who interacted with the teenager, all of whom returned negative results. Dr. Bonnie Henry, the province’s health officer, confirmed that these individuals were given antiviral medications as a precautionary measure. Pets of the affected individual were also tested with negative results.
Although no outbreaks of bird flu have been reported on Canadian dairy farms, health officials noted that the virus has been found in at least two dozen poultry farms since October 2024. They emphasize the importance of tracing the source of exposure, though Dr. Henry cautioned that it might remain a mystery. She stated, “There is a very real possibility that we may not ever determine the source, but at this point, we have a number of leads that we’re following.”
The specifics regarding the teenager's identity, including age and gender, have not been disclosed. Previously, the patient sought treatment at a hospital for respiratory distress symptoms, including pink eye, fever, and cough, but was sent home before being readmitted to B.C. Children’s Hospital.
Alarmingly, there has only been one other case involving a Canadian, which resulted in a fatality following exposure during a visit to China, the virus's original hotspot. As a precaution, authorities are advising the public to refrain from handling dead birds and are urging poultry farmers to keep their flocks indoors to minimize disease spread. Dr. Brian Ward from McGill University cautioned that avian influenza viruses are on the move across North America, further highlighting the need for vigilance among those in the poultry industry.
