MOSCOW, May 29 (RIA Novosti) - Bird flu has been registered in 10 villages in three West Siberian regions, the Russian Agriculture Ministry said Monday.

"The Novosibirsk and Omsk regions and the Altai Territory remain unfavorable in terms of bird flu outbreaks," the ministry said.

The deadly disease, which has claimed dozens of human lives, has been registered in three villages in the Novosibirsk Region, five in the Omsk Region and two in the Altai Territory.

Although no human lives have been claimed to date in Russia, around 1.1 million birds have died of the disease and 300,000 have been culled to control the spread of the virus since the beginning of February.

Almost 140 million doses of a vaccine had been delivered to Federation members by May 26.

In addition to the problems in Siberia, bird flu has been identified in 11 regions of the Southern Federal District since the start of the year, but health authorities are confident that the situation is now under control.

"Owing to veterinary measures, all outbreaks of the virus were eliminated in the Southern Federal District," the source said.
