Surveillance has revealed evidence of the avian influenza virus; H5 and H6 sub-types; at three further ostrich farms in Western Cape, the same province where previous outbreaks occurred. All three premises were commercial ostrich farms. Farms tested positive on serology during routine surveillance but tested negative on PCR and no virus could be found. Diagnosis only confirmed after several follow-up PCR tests.Initially no clinical signs or mortalities were seen. Stamping out in positive farms is taking place.
