Findings also suggest that poultry trade seasonality may affect the risk of HPAI H5N1 spread (Soares Magalhaes et al., 2012). Most studies focused on the influence of the Chinese New Year only, and quantitative data on the spatial and temporal dynamics of poultry flows in Southeast Asia are still lacking. Moreover, although the pattern of live poultry trade in Thailand may differ from that of other Asian countries, it is still poorly explored. Unlike Cambodia, Vietnam, and China, live bird markets are rare in Thailand (Tiensin et al., 2009).
