Hello, please pay attention:
A Nevada dairy worker has contracted the deadly D1.1 strain of bird flu, seen in a British Columbia teen who recovered and a Louisiana victim who died.
This mutated strain spreads rapidly among mammals, including cattle, and is moving faster than others.
Migrating birds will spread it globally, increasing the risk of more outbreaks.
What started in the U.S. is now a global threat.
A bird flu pandemic is almost here.
