    Epidemiology
    Source of the outbreak(s) or origin of infection • Introduction of new live animals
    • Legal movement of animals
    Epidemiological comments An active surveillance for avian influenza in 5 targeted provinces of Northern Laos started in July 2014 with financial support from the United States Agency for International Development (USAID) through Food and Agriculture Organization (FAO). As of 15 September 2014, the laboratory diagnostic results from the National Animal Health Laboratory (NAHL) have revealed that a poultry farm where were introduced one-day-old chicken and ducks was positive for H5N6 as confirmed by real-time PCR. It is now planned to send the positive samples to the Australian Animal Health Laboratory for sequencing.

    First appearance of H5N6 in Laotian poultry

    Low-pathogenic H5N6 avian flu, reported as a new strain in several outbreaks in Vietnam since August, has now appeared in Laos, says a report yesterday from the World Organization for Animal Health (OIE).

    Two birds in a flock of 200 on a poultry farm in Viengsavang, Luangprabang, showed signs of clinical disease and died, for an apparent morbidity rate of 1% and an apparent case-mortality rate of 100%.

    Testing by real-time polymerase chain reaction (PCR) at the National Animal Health Laboratory confirmed H5N6. The remaining birds in the flock were destroyed.
    The report says active surveillance for avian flu was started in five Laotian provinces in July with support from the US Agency for International Development through the Food and Agriculture Organization of the United Nations.
