Avian Flu Update - Czech
Republic & Russia
Czech Republic - Swans

CTK Czech News Agency

Vets have discovered 2 new cases of bird flu in dead swans found in southern Moravia, State Veterinary Authority spokesman Josef Duben said. Tests have confirmed the H5 virus in both birds, and a highly contagious form in one case, he added.
In all, 14 cases of bird flu have occurred in the Czech Republic. The previous 12 dead swans were found in South Bohemia and all of them were infected with the H5N1 strain, dangerous to humans.
Special measures will now be introduced in the critical area. The towns and villages situated in the zones of strict protection and supervision must make a count of all household poultry breeds and secure containers for the dead birds.
Local breeders must not keep poultry in open-air enclosures.
A ban will be imposed on the transfer of poultry, eggs and further material, and access to poultry farms will be limited. Steps will be taken to secure disinfection of the people and cars in contact with the farms.
The measures are to last at least 21 days. The previous special measures were cancelled on 10 May 2006.
According to the recent update (19 May 2006) of EU's Animal Disease
Notification System (ADNS), 10 new HPAI cases in wild birds have been added
this week to the list of 455 wild birds reported since the beginning of
2006 until 12 May 2006 (previous weekly report). These new cases were
reported from Germany (5), Poland (one), and Italy (4, probably detected in
March). Obviously the new cases in the Czech republic are not yet included
in these statistics. See

Tests have confirmed that 86 dead chickens found in the village of Maksimovka in the Omsk region between 29 Apr and 13 May were infected with the H5N1 bird flu strain, the press service of the Emergency Situations Ministry's Siberian branch told Interfax on Tuesday 16 May 2006.
"Examinations have confirmed the bird flu virus. A total of 3893 domestic birds have already been inoculated against the disease in the village," the press service said.
No poultry deaths have been reported over the last 24 hours, it said. The village has been quarantined.
Russia, Western Siberia - Poultry

The avian flu virus which killed birds in the Novosibirsk and Omsk regions in late April-early May 2006 does not significantly differ from the virus exposed in Siberia during 2005.
"The H5N1 virus most likely had the same source as the spring outbreak at Lake Qinghai in China," Alexander Shestopalov, head of the laboratory monitoring and studying zoonotic infections, told Interfax.
"This year's virus is almost the same by its pathological characteristics and methods of transmission. It still has a fecal-oral way of transmission, instead of aerosolic," the expert said.
2 villages in the Novosibirsk region and 3 in the Omsk region have registered cases of bird flu in 2006.
The West-Siberian oblasts Novosibirsk and Omsk, bordering to their south Mongolia and Kazachstan, were the first Russian territories to be infected by the H5N1 virus in 2005. The outbreak began in early July in Novosibirsk, spreading initially to Omsk and Tyumen and then further west. The outbreak in wild birds in Qinghai, China, had taken place earlier, probably beginning in May. Alexander Shestopalov might be right in pointing to similarities between the chronologies of 2005 and 2006. - Mod.AS
