A growing threat is emerging as seasonal influenza cases surge in Canada, with reports of avian flu infecting birds like Canadian geese. Health officials are closely monitoring the potential fusion of human and bird flu strains, which could create a highly-contagious and deadly new pathogen.
Influenza viruses have been exchanging genetic material rapidly, allowing them to quickly acquire new traits and adapt. If the viruses mix, it could give rise to a pandemic with “pandemic potential.” The risk is currently low, but every time the virus jumps to a new species, it raises concerns.
Human infection with avian influenza is rare, usually occurring after close contact with infected birds or highly contaminated environments. However, as flu viruses continue to evolve in animals and have the potential to adapt to humans, the risk remains a concern.
Symptoms of bird flu can overlap with seasonal influenza, making detection challenging. Severe conjunctivitis or pink eye is a rare but key warning sign for doctors. The risk to the public remains low, but health officials warn that it’s not a slow gradient of increased risk over time.
