H5N1 highly pathogenic avian influenza in Southeast Asia.Rev Sci Tech 2009; 28(1):341-8RS
Since the first H5N1 highly pathogenic avian influenza virus (HPAIV) infection in the region in August 2003, Cambodia, Laos, Malaysia, Myanmar, Indonesia, Thailand and Vietnam have all recorded outbreaks of the disease. The HPAIV continues to occur in some countries in Southeast Asia despite control programmes encompassing surveillance, vaccination and stamping out strategies. A number of strains have been circulating in the region since the first outbreaks in 2003, and although the source of the initial outbreaks in domestic poultry is not known, the continuing propagation of disease in the region is primarily the result of the movement of domestic poultry and poultry products, and people. A comprehensive approach using all the strategies available to break the chain of transmission of the virus in poultry will be needed to achieve lasting disease control.
