First Presumptive Human Case of Avian Flu Acquired in Canada Detected in Teen

British Columbia health officials report a teenager’s positive test for H5N1 avian influenza, marking a significant development in Canada’s public health landscape.

In a unwelcome development, British Columbia’s Ministry of Health has announced the first suspected human case of avian influenza (H5N1) contracted within Canada. A teenager residing in the Fraser Health region has tested positive for the virus and is currently receiving treatment at BC Children’s Hospital.
The initial positive result was obtained by the BC Centre for Disease Control, with confirmatory testing underway at the National Microbiology Laboratory in Winnipeg. Public health officials are actively investigating the source of exposure and identifying potential contacts to prevent further transmission.
Provincial Health Officer Dr. Bonnie Henry emphasized the rarity of such cases, stating, “This is a rare event.” Globally, human infections with the H5N1 strain have been infrequent, with only a handful of cases reported in the United States and other countries.
The source of the teenager’s exposure is believed to be from an animal or bird, prompting a collaborative investigation between public health authorities and the province’s chief veterinarian. This case underscores the importance of monitoring zoonotic diseases—those that can be transmitted from animals to humans—and implementing preventive measures to safeguard public health.

Understanding Avian Influenza (H5N1)

Avian influenza, commonly known as bird flu, is an infectious viral disease that primarily affects birds but can occasionally infect humans. The H5N1 strain is highly pathogenic among avian species and has been associated with severe respiratory illness in humans. Transmission to humans typically occurs through direct contact with infected birds or contaminated environments. Human-to-human transmission is extremely rare.

Global Context and Canada’s Preparedness

Since its emergence, H5N1 has caused outbreaks in poultry populations worldwide, leading to significant economic losses and public health concerns. According to the World Health Organization, from 2003 to 2021, there were 862 human cases of H5N1 globally, resulting in 455 deaths, indicating a high case fatality rate.
In response to the global spread of H5N1, Canada has implemented robust surveillance and control measures. The Canadian Food Inspection Agency (CFIA) monitors avian influenza in domestic and wild bird populations, while the Public Health Agency of Canada (PHAC) oversees human health aspects. These agencies collaborate to detect and respond to avian influenza cases promptly.

Implications for Chestermere and Surrounding Areas

While this case has been identified in British Columbia, residents of Chestermere and the broader Alberta region should remain informed and vigilant. The risk to the general public remains low; however, individuals who have direct contact with birds, such as poultry farmers, hunters, and bird handlers, should adhere to recommended safety protocols.

Preventive Measures and Recommendations

To minimize the risk of avian influenza transmission, the following precautions are advised:
Avoid Direct Contact: Refrain from handling wild birds or poultry that appear ill or have died unexpectedly.
Practice Good Hygiene: Wash hands thoroughly with soap and water after handling birds or their environments.
Cook Poultry Properly: Ensure that all poultry and eggs are cooked to an internal temperature of 74°C (165°F) to eliminate potential viruses.
Report Unusual Bird Deaths: Notify local animal health authorities if you observe a sudden increase in bird deaths.
Use Personal Protective Equipment (PPE): Individuals working with birds should use appropriate PPE, including gloves and masks, to reduce exposure risk.

Public Health Response and Future Outlook
Health authorities continue to monitor the situation closely, conducting thorough investigations to trace the source of infection and prevent further cases. This incident serves as a reminder of the importance of ongoing surveillance and public awareness in managing zoonotic diseases.
Residents are encouraged to stay informed through official public health channels and to follow guidance provided by health authorities. By working together and adhering to recommended precautions, communities can effectively mitigate the risks associated with avian influenza.
