Seven employees of a poultry farm in the south of the country fell ill in December. Those affected are fine, they have recovered. The disease was mild.
The disinfection work should be completed in the next few days and new chickens should be bought in mid-April, it said. There are three poultry farms in the region that specialize primarily in the production of eggs.
The vector research center in the Siberian city of Novosibirsk had proven that the employees were transmitted with the H5N8 virus.
“With avian influenza viruses there is always the possibility of a quick change in the properties,” said a spokeswoman for the German Press Agency in Moscow on Sunday. In addition, with a high viral load, as in affected companies, it must be expected that there will be transmissions one day.
The Friedrich Loeffler Institute now wants to get more information on the cases in Russia, said the spokeswoman. She reminded of the applicable hygiene rules: dead wild birds should therefore not be touched with bare hands. If it does come into contact, hands should be washed thoroughly. If poultry farms affected are evacuated, protective clothing is worn.
In Austria, too, outbreaks of bird flu have been detected in animals on several occasions. The highest incidence and death rates are observed in chickens and turkeys. Avian flu occurs with different subtypes. Several had already known that people could be infected with it. Transmission via infected food is however unlikely. The German Friedrich Loeffler Institute announced on Friday that the risk of the disease spreading further was still high.
According to the institute, the H5N8 virus has not yet been transmitted to humans. “With avian influenza viruses there is always the possibility of a quick change in the properties,” said a spokeswoman on Sunday. In addition, with a high viral load, as in affected companies, it must be expected that there will be transmissions one day.
There are several subtypes of avian flu viruses, including the H5N1 virus, which can cause serious illness in humans. The mortality rate is 60 percent. The last major outbreak of avian influenza in European countries occurred in the winter of 2016/17.
The so-called avian influenza was first observed in Italy in 1878. The pathogens occur worldwide, reports AGES. In Austria, the AGES national reference laboratory has been investigating an increasing number of wild birds found dead in recent weeks: On February 4, 2021, a swan found dead in Lower Austria (Klosterneuburg) was diagnosed with the highly pathogenic avian influenza virus (HPAI, serotype H5N8).
Further cases were confirmed on February 10: a swan in Vienna (H5N8) and two swans in southern Styria (H5N5).
