Hi itsy,
This part and fear-mongering are the 'scary' parts IMO:
"It has also killed or provoked the culling of more than 400m domestic poultry worldwide and caused an estimated $20bn (£12.2bn) of economic damage."
So I think this article refers to a mutant of the H5N1 virus, and there is also concern that H2N2 flu virus is on the rise. The second one only dangerous to people under age 50 I think.
Time to educate people that many people don't use the same flock raising methods employed in SouthEast Asia, and for all of us to be more aware of biosecurity for our birds.
