      Epidemiological comments New outbreaks in this report are as follows: Case 1: On 11th November, one Cygnus olor (mute swan) was found dead in Matsue-shi and the sample taken tested positive for influenza A virus by antigen-capture kit. On 20th November, the sample was confirmed positive for H5N6 subtype influenza A virus. Case 2: On 12th November, one Cygnus olor (mute swan) was found dead in Matsue-shi and the sample taken tested positive for influenza A virus by antigen-capture kit. On 20th November, the sample was confirmed positive for H5N6 subtype influenza A virus. Case 3: On 12th November, one Aythya fuligula (tufted duck) was found dead in Matsue-shi and the sample taken tested negative for influenza A virus by antigen-capture kit but positive for genome diagnosis. On 20th November, the sample was confirmed positive for H5N6 subtype influenza A virus.
