Key result
A higher number of confined farms per commune was significantly associated with an increased risk of African swine fever virus occurrence (OR 2.21), while a higher proportion of censused open farms was protective.

May guide risk-based ASF surveillance in confined farm areas; leaves open causality and generalizability beyond Sardinia.
Observational (n=376)
Odds Ratio: 2.21 (95% CI 1.23–4.13)
p-value: p=<0.05
Socio-cultural and productive factors, such as the number of confined backyard farms and road density, are significant risk factors for African swine fever occurrence in Sardinia.
Martínez‐López et al. (2015) conducted an observational in African swine fever (n=376). Number of confined/closed farms vs. Fewer confined/closed farms was evaluated on African swine fever virus occurrence (OR 2.21, 95% CI 1.23-4.13, p=<0.05). A higher number of confined farms per commune was significantly associated with an increased risk of African swine fever virus occurrence (OR 2.21), while a higher proportion of censused open farms was protective.
