Introduction

H5N1 Avian Influenza, the worst threat to the poultry farming in Thailand, caused drastic losses to the livestock farming throughout the world as well as the country. The Avian Influenza viruses affect not only the livestocks but also human beings in the worst cases. In this regard a study was conducted to visualize the pattern of H5N1 Avian Influenza outbreaks and its impact on the various livestocks in Thailand using GIS maps. The spatial analysis was concentrated only on livestocks and not on human beings. The website includes disease incidence, diffusion and emergence of H5N1 outbreak mapping as well as livestock mapping. The maps are produced based on the absolute number and density of holdings and species, by district and sub district. This analysis was carried out for over a period of 4 years from 03.07.2004 to 01.12.2008.
