U.S. satellites tracking infected flocks with bird flu
virus
In a remarkable speech in mid March of 2006, Secretary of Health and Human Services
Michael Leavitt recommended that Americans start storing canned tuna and powdered milk
under their beds as the prospect of a deadly bird flu outbreak approaches the United
States.
Bird flu is being spread much faster than first predicted from one wild flock of birds to
another, an airborne delivery system that no government can stop.
"There's no way you can protect the United States by building a big cage around it
and preventing wild birds from flying in and out," U.S. Secretary of Agriculture
Michael Johanns said.
U.S. spy satellites are tracking the infected flocks, which started in Asia and are now
heading north to Siberia and Alaska, where they will soon mingle with flocks from the
North American flyways.
"What we're watching in real time is evolution," said Laurie Garrett, a senior
fellow for global health at the Council on Foreign Relations. "And it's a biological
process, and it is, by definition, unpredictable."
Industry Precautions
America's poultry farms could become ground zero as infected flocks fly over. The industry
says it is prepared for quick action.
"All the birds involved in it would be destroyed, and the area would be isolated and
quarantined," said Richard Lobb of the National Chicken Council. "It would very
much [look] like a sort of military operation if it came to that."
Extraordinary precautions are already being taken at the huge chicken farms in Lancaster
County, Pa., the site of the last great outbreak of a similar bird flu 20 years ago.
Other than the farmers, everyone there has to dress as if it were a visit to a hospital
operating room.
"Back in 1983-1984, we had to kill 17 million birds at a cost of $60
million," said Dr. Sherrill Davison, a veterinary medicine expert at the
University of Pennsylvania.
Can It Be Stopped?
Even on a model farm, ABC News saw a pond just outside the protected barns attracting wild
geese.
It is the droppings of infected waterfowl that carry the virus.
The bird flu virus, to date, is still not easily transmitted to humans. There have been
lots of dead birds on three continents, but so far fewer than 100 reported human deaths.
But should that change, the spread could be rapid.
ABC News has obtained a mathematical projection prepared by federal scientists based on an
initial outbreak on an East Coast chicken farm in which humans are infected. Within three
months, with no vaccine, almost half of the country would have the flu.
That, of course, is a worst-case scenario -- one that Lobb says the poultry industry is
determined to prevent with an aggressive strategy to contain and destroy infected flocks
and deny the virus the opportunity to mutate to a more dangerous form but one that experts
say cannot be completely discounted.
The current bird flu strain has been around for at least 10 years and has taken surprising
twists and turns -- not the least of which is that it's now showing up in cats in Europe,
where officials are advising owners to bring their cats inside. It's advice that might
soon have to be considered here.
