"The chances of getting bird flu off a pet bird or your neighbours birds are so infinitesimally small," UQ School of Veterinary Science Adjunct Professor Dr Doneley said.

Authorities have confirmed the dangerous H5NI strain of bird flu in South East Asia, Russia and Eastern Europe but not in Australia.
They fear an epidemic if this strain mutates to spread into a people-to-people virus.
"We need to be very alert for bird flu in poultry because the more people who get it from birds, the higher the chance that the virus could change."
