H5N6 Bird Flu Outbreak in Vietnamese Provinces14 August 2014
VIET NAM - The Vietnamese veterinary authorities have reported two fresh outbreaks of highly pathogenic (H5N6) bird flu in Lang Son and Ha Tinh provinces.
The World Organisation for Animal Health (OIE) received an immediate notification on Tuesday, 12 August. According to the report, this is a new strain detected from outbreak surveillance activities. The initial result was positive for H5 but negative for N1. As a result, further testing was needed and the final result was only available in July 2014 (N6 positive).
The report states that a total of 1980 birds were found susceptible, out of which 950 birds were found to be infected. A total of 15 deaths were reported and the remaining 1965 birds were destroyed.
According to the OIE, all poultry in affected flocks were destroyed immediately when poultry showing clinical signs of HPAI (highly pathogenic avian influenza) were detected. Samples were taken from surrounding poultry flocks. All were negative for avian influenza.
On 16 July, a real-time reverse transcriptase/polymerase chain reaction (RRT-PCR) test was carried out at the National Centre for Veterinary Diagnosis (NCVD). The test resulted positive.
The source of the outbreaks remains inconclusive.
Several control measures have been applied to contain the situation, thereby preventing further spread of the disease.
