Birds don't become sick when exposed to the H1N1 influenza strains that caused the 1918 and 2009 global flu pandemics, which suggests birds played no role in the spread of the pandemic-causing viruses.
To investigate how major human pandemic flu viruses affect birds and other domestic animal species in order to discover the role birds and animals in spreading viruses in the human population, researchers from Canada and USA injected the 1918 and 2009 H1N1 flu virus strains into chickens.
After 18 days, none of the birds had developed flu symptoms or showed any signs of tissue damage. The 1918 H1N1 virus also didn't cause disease in ducks. This indicates that birds are unlikely to have played a part in the spread of the 1918 and latest 2009 H1N1 pandemic viruses.
The above finding can help guide decisions about how to respond to influenza outbreaks in poultry. The findings support the use of normal veterinary management practices in poultry infected with pandemic 2009 H1N1 influenza and demonstrate that quarantining and culling infected stocks is not necessary.
