Bird flu’s momentum in Canada worries experts: ‘Potential to become a pandemic’
, shows there are 1,829 confirmed and suspected cases of bird flu in animals overall in Canada as of Friday. The majority of cases are in Quebec , Alberta and Saskatchewan .Some flu viruses mainly affect people, but others chiefly occur in animals. For example, there are flus that occur in dogs, as well as pig – or swine – flu viruses. Then there are avian viruses that spread naturally in wild aquatic birds like ducks and geese, and then to chickens and other domesticated poultry.
The bird flu virus drawing attention today –Type A H5N1– was first identified in 1959 by investigators looking into a flu outbreak in chickens in Scotland. Like other viruses, it has evolved over time, spawning newer versions of itself.Over the last year, there has been a large virus outbreak in waterfowl — such as geese — that migrate from Europe to North and South America, he explained. And as these birds migrate, they spread the virus, which is why outbreaks are starting to spread in the U.S.
There is also more spillover to other wildlife, including seals and skunks, as well as livestock on mink farms.in the Vancouver area tested positive for the H5N1 avian influenza. B.C. health officials said the skunks may have contracted the virus by eating infected wild birds.in at least two species of seals as an unusually high number of these mammal’s carcasses were washing up on the province’s shorelines.
“The risk of avian flu infection is low for the general public who has limited contact with infected animals; those with close contact to infected animals are at increased risk, and should take appropriate precautions,” Health Canada said in an email to Global News Friday., where an 11-year-old girl, who lived near a conservation area, reportedly died from the virus.
