    • 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).
