    Highly pathogenic avian influenza, Cote D'Ivoire

    Information received on 20/11/2009 from Dr Kanga Kouame, Directeur des Services Vétérinaires et de la Qualité, -, Ministère de la Production Animale et des Ressources Halieutiques, Abidjan, Cote D'Ivoire

    • Summary

      • Report date 20/11/2009
      • Date submitted to OIE 20/11/2009
      • Date event resolved 30/10/2009
      • Reason for notification Reoccurrence of a listed disease
      • Date of previous occurrence 01/2007
      • Manifestation of disease Sub-clinical infection
      • Causal agent Highly pathogenic avian influenza virus
      • Serotype H5N1
      • Nature of diagnosis Laboratory (advanced)
      • This event pertains to a defined zone within the country

    • Outbreaks
      • There are no new outbreaks in this report

    • Epidemiology
      • Source of the outbreak(s) or origin of infection
        • Unknown or inconclusive

    • Epidemiological comments
      • The reoccurrence of highly pathogenic avian influenza serotype H5N1 is not confirmed and will be closed since the results obtained by the OIE Reference Laboratory in Padova were negative for avian influenza by RT-PCR, virus isolation in embryonated eggs, sequencing, intravenous pathogenicity index test and hemagglutination inhibition test. Further tests were carried out by the same laboratory for Newcastle disease and West Nile fever and they were negative.
      • Concerning the ravens that died in Abidjan, some people have revealed that they had spread a toxic product, mainly Gambaril; that could be the origin of the deaths reported. Toxicological tests gave negative results.
