  • Northern Vietnam: Porcine Reproductive & Respiratory Syndrome (PRRS).

    Blue ear disease attacks pigs in northern Vietnam
    Hundreds of pigs have died since last month in northern Vietnam of Porcine Reproductive & Respiratory Syndrome (PRRS). The Central Steering Committee for Bird Flu Control and the Animal Health Department Tuesday held a meeting and announced PRRS, also known as blue ear disease, had infected **** Yen, Bac Ninh, Bac Giang, and Thai Binh provinces, and Hai Phong and Hanoi cities.
    The disease first broke out in Hai Duong where tens of thousands of pigs are now infected.
    Trinh Van Quyet, **** Yen veterinary department head, said over 1,000 pigs in eight out of 10 districts in his province had been infected, 217 fatally.
    Many pig farmers have gone bankrupt.
    As the name suggests, the disease causes blueing of the ears, besides lack of appetite, high fever, miscarriage and premature delivery among sows, coughing and respiratory problems, and death in extreme cases.http://www.thanhniennews.com/healthy...8&newsid=26959

    [ProMED and PRO/MBDS would like to thank Dr. Huu Dung for alerting us
    to the OIE report on the PRRS outbreak in Viet Nam.

    A good map with affected areas highlighted can be found at the above
    given URL link for the WAHID report. - Mod. MPP]

    [PRRS is a disease of great importance to the swine industry wherever
    it occurs. We are therefore very pleased to see the excellent
    communication efforts made by the Vietnamese animal health
    authorities. It is important that all concerned with both regional
    and global animal health be apprised of its spread. We also
    appreciate the clarification of the exact locations where the disease
    affected swine.

    In case anyone wonders what PRO/MBDS signifies, it is a regional
    ProMED-mail list similar to ProMED-PORT (Portuguese), ProMED-ESP
    (Spanish) and ProMED-RUS (Russia and Newly Independent States. It has
    been championed by Mod. MPP, and we can see the value by the
    timeliness of these reports.

    Similar efforts throughout the Middle East and regions of Africa
    (West, East, South and North) would improve global alertness and
    response to emerging diseases in humans, animals and plants.
