Epidemiological comments

This outbreak is more than 1,000 km away from any other reported H7N1 or H7N7 outbreaks and occurred in species other than ostriches. There is no evidence to link this outbreak to previous outbreaks. This outbreak occurred in indigenous wild birds and an exotic parrot kept in captivity. The birds were tested for planned export. They tested positive on RT-PCR for H7. The samples did not render enough material to allow sequencing or virus isolation and the N-type could not be determined. It is highly unlikely that further information on the N-type will be obtained. For this reason, the veterinary services decided to report it as a new event.

Note by the OIE Animal Health Information Department: H5 and H7 avian influenza in its low pathogenic form in poultry is a notifiable disease as per Chapter 10.4. on avian influenza of the Terrestrial Animal Health Code (2012).
