Habitat loss exacerbates pathogen spread: An Agent-based model of avian influenza infection in migratory waterfowl

Habitat availability determines the distribution of migratory waterfowl along their flyway, which further influences the transmission and spatial spread of avian influenza virus (AIV). The extensive habitat loss in the East Asian-Australasian Flyway (EAAF) may have altered AIV spread and transmission, but those consequences are rarely studied. Yin et al. constructed migration networks that differed in the level of habitat loss and integrated Agent-based model and SIR model to simulate waterfowl migration and AIV transmission. The results suggested that an extensive habitat loss can increase AIV outbreak risk in remaining habitats and facilitate transmission due to larger congregations. Yin et al
