Terrain of Feared Bird Flu Strain Expands
Russian veterinary officials said an outbreak of an avian flu strain that can infect humans had spread to another region in Siberia.
The outbreak began in the Novosibirsk region in early July and has killed thousands of domestic fowl. Last week, the veterinary service identified the virus as the H5N1 strain, which can kill people, but no human cases have been reported in Russia. The same strain has been reported in a village in the adjacent Altai territory and in the Tyumen region farther west.
