After the H5N2 outbreak identified on 21 March 2011, an epidemiological and clinical investigation was conducted on the surrounding poultry farms within a 3-km-radius of the index farm. In this investigation, the notifiable avian influenza (NAI) viral infection was detected on a duck breeder farm and identified as H7N3 strain on 7 April 2011. Movement restriction was implemented on the farm immediately after the virus was detected. Clinical investigation on that farm was done and showed that the breeders were healthy and without abnormal mortality and dropping of egg production. The positive results of serological and virological tests confirmed this new outbreak. The pathogenicity assays of this virus isolate are on-going.
