A retrospective study was conducted to evaluate the epidemiological characteristics of the epidemic and the risk factors associated with the ASF at the household farm level. There were 285 households farms in the surveying areas, of which 173 household farms having the ASF cases were interviewed to collect the target information using the questionnaires.
