    Epidemiological comments

    The national surveillance plan for avian influenza is being applied and samples are being taken in fighting cocks, backyard birds and birds in markets and in commercial bird farms in the whole country.

    Surveillance was intensified following the first outbreak of the disease on 10 December 2007.

    Since that date and until 28 February 2008, samples were taken in 14,876 backyard birds.

    All positive birds and all in-contact birds in the outbreaks were slaughtered and cleaning and disinfection of all affected farms were implemented.

    Surveillance is on-going in the protection zones and monitoring has been intensified in commercial farms.

    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 2.7.12. on avian influenza of the Terrestrial Animal Health Code.
