Seven workers at a poultry farm in the south of the country have been infected with the virus, officials said. Ms Papova said there was no sign of the virus being passed from person to person.
“Discovering these mutations, when the virus is not yet able to transmit from one human to another, gives us, and indeed the whole world, time for possible mutations and to respond to them effectively and in a timely manner,” he said. “Let’s be ready.”
Other species of bird flu have sometimes infected humans and in some cases been fatal, but this is the first case of H5N8 transmission from chicken to humans.
