ASF entry risk assessment model
We used the risk assessment model that we previously developed (Sugiura et al., 2020), reparametrizing the variables that are deemed to be affected under the coronavirus pandemic, namely the number of air travelers from China and the amount of food waste from restaurants. We assumed that variables other than these two do not change even under the coronavirus pandemic. The number of infected pig farms in China remained more or less the same during the first four months of 2020 (OIE, 2020). The simulation was performed using @Risk Version 7.6 (Palisade, Ithaca, New York) within Microsoft® Excel 2013, and was run with 10,000 iterations using Latin Hybercube sampling for each simulation.
