BIRD FLU ON THE WING? NOT A CHANCE

CLAIM: THREAT OF VIRUS SPREADING THROUGH MIGRATING BIRDS IS FALSE

ATTENTION TURNS BACK TO BUSINESS PRACTICES OF POULTRY FARMS

From The New York Times : "ROME, May 10 — Defying the dire predictions of health officials, the flocks of migratory birds that flew south to Africa last fall, then back over Europe in recent weeks did not carry the deadly bird flu virus or spread it during their annual journey, scientists have concluded.

"International health officials had feared that the disease was likely to spread to Africa during the southward migration and return to Europe with a vengeance during the reverse migration this spring. That has not happened — a significant finding for Europe, because it is far easier to monitor a virus that exists domestically on farms but not in the wild.

"In thousands of samples collected in Africa this winter, the bird flu virus, A(H5N1), was not detected in a single wild bird, health officials and scientists said. In Europe, only a few cases have been detected in wild birds since April 1, at the height of the migration north.

"The number of cases in Europe has fallen off so steeply compared with February, when dozens of new cases were found daily, that specialists contend that the northward spring migration played no role.

"In response to the good news, agriculture officials in many European countries are lifting restrictions intended to protect valuable poultry from infected wild birds.

"...the lack of wild bird cases in Europe only underscores how little is understood about the virus. And scientists warn that it could return to Europe.

"While bird flu has become a huge problem in poultry on farms in a few African countries, including Egypt, Nigeria and Sudan, specialists increasingly suspect that it was introduced in those countries through imported infected poultry and poultry products....the strength of the virus among wild birds possibly weakened as the southward migration season progressed..."
