Researchers from the European Food Safety Authority (EFSA) have utilized data from northern Italy to model the impact of wild boar density on the spread of African swine fever (ASF) using a spatially explicit detection delay (SIR) model. The study, which incorporates epidemiological data and wild boar density estimates, suggests that during the second wave of the outbreak in Italy, wild boar density may have contributed to ASF transmission. The model, with adjustable transmission rates and habitat susceptibility/infectivity, could be applied to other epidemic situations to further understand the role of wild boar density in disease spread.
