The map displays the most recent reporting of avian influenza outbreaks in Thailand as published by the Office International des Epizooties (OIE, 2004). The mapping has been produced on a provincial basis, requiring “Bangkok Province” (as named in the data source: OIE, 2004) to be mapped to Krung Thep Province. Access to improved geographical data, e.g., sub province, would enable the mapping to be more precise, making full use of the level of detail published by OIE. Produced by: Microbial Risk Assessment Team, HPA Porton Down. In collaboration with colleagues at ProMED-mail, Oracle Corporation, and Environmental Systems Institute, Inc. (UK) Health Protection Agency are developing a mapping front end to the ProMED website.
