The relationship between environmental factors and the onsets of avian influenza virus (AIV; H5N1) outbreaks in Thailand was studied. The results show that the onsets of the disease correlate with the maximum gradient of temperature and wind speed within 24 hours, density of villages in a radius of five kilometers, and distance from the last AIV outbreak area. This study also presents how meteorological conditions have an effect on the occurrence of onsets of AIV in Thailand.
