Cygne trouvé mort à Matsue, atteint par virus HN6
TOKYO (Kyodo) -- The Environment Ministry said Thursday a dead wild swan found at a western Japan lake was infected with a highly pathogenic avian influenza virus, confirming it as the first bird flu case in the country this season.
A detailed examination conducted at Tottori University determined the presence of the H5N6 influenza strain, which has caused severe outbreaks in Japan and Asia in the past, according to the ministry.
The dead mute swan was discovered near Lake Shinji in Matsue, Shimane Prefecture, on Sunday and it tested positive for bird flu in a simple test carried out by the prefectural government.
Since Sunday, the ministry has intensified its monitoring of wild birds within a 10-kilometer area of the site where the dead swan was discovered, while elevating the 3-stage alert level Thursday from level 1 to 2.
The ministry will dispatch experts to the site from next week to assess the situation. It will also examine dead birds more closely to ascertain whether they were infected with the bird flu virus.
The Shimane prefectural government will begin inspections across the entire prefecture from Friday, planning to alert poultry farmers around the area and conduct on-site inspections.
Initial testing on a tufted duck found dead on the other side of Lake Shinji Tuesday indicated it may have carried bird flu, the university is examining the bird further to confirm.
In Japan, hundreds of thousands of chickens were culled at poultry farms in Miyagi and Chiba prefectures in March this year following the outbreak of bird flu caused by highly virulent H5N6 strain.
