Cats reported sick, dying from H5N1 infection; CFIA offers tips to help keep pets safe
According to the CFIA, animals that hunt, scavenge or otherwise consume infected birds are at risk. For example, cats that go outdoors may hunt and consume an infected bird. Dogs may scavenge dead birds. “If your pet has found a sick or dead bird or other wildlife, report it to your regional avian influenza hotline or the Canadian Wildlife Health Cooperative,” advises the CFIA.
Bird flu testing shows more dairy products are safe, US FDA says
The U.S. Food and Drug Administration said on Wednesday that preliminary results of additional testing of more dairy products has shown that pasteurization inactivates the bird flu virus.
Bird flu strain raises alarm as virus kills South American wildlife
Mammal-to-mammal transmission of virus likely but unconfirmed, scientists say
The deadly H5N1 bird flu virus has spread more aggressively than ever before in wild birds and marine mammals since arriving in South America in 2022, raising the risk of it evolving into a bigger threat to humans, according to interviews with eight scientists.
France stacks the deck against bird flu but risks issues
France has launched its bird vaccination scheme amid fears of repeat H5N1 outbreaks
Of all the emerging and potentially pandemic viruses, the highly pathogenic avian influenza (HPAI) virus H5N1 is one of the fiercest. First found in Hong Kong in 1997, it has a 60 per cent mortality rate when transmitted to humans. As of August, the World Health Organization has counted 878 human cases and 458 deaths
Canada books first month in 19 without bird flu outbreak
Eight commercial poultry farms remain active sites
June 2023 appears set to be Canada’s first month without a new highly pathogenic avian influenza outbreak in poultry or other domesticated birds since the disease returned to this country in late 2021. Canada has booked 322 outbreaks in domestic birds in the past 19 months, of which 31 were detected so far in 2023.
Scientists isolate human gene able to fend off most bird flu viruses
Finding may show which bird flu strains have human pandemic potential
London | Reuters — U.K. researchers have homed in on a human gene implicated in thwarting most bird flu viruses from infecting people. Bird flu chiefly spreads among wild birds such as ducks and gulls and can also infect farmed birds and domestic poultry such as chickens, turkeys and quails. Although the viruses largely affect
