The veterinary authority sent Follow Up report No. 6 dated 26 August to the World Organisation for Animal Health (OIE).

According to the report, 30 ostriches at a farm of 115 birds at Oudtshoorn in Western Cape Province were HI positive for H5 on 14 July.

The report adds that this was a commercial ostrich farm. The farm tested positive on serology during routine surveillance, but tested negative on PCR and no virus could be found. Diagnosis was only confirmed after several follow-up PCR tests. South Africa only reports outbreaks on confirmation on PCR tests. Initially, no clinical signs or mortalities were seen. Stamping out in positive farms is taking place.
