Abstract
Porcine epidemic diarrhea (PED) is caused by the PED virus (PEDV), which is characterized by enteritis, vomiting, and watery diarrhea. The study was conducted a retrospective investigation of 63 small-scale farms, including 31 case farms and 32 control farms by a case-control study with a questionnaire including risk factors that could play a role in the spreading of PEDV. Thirteen risk factors as 13 independent variables included in the univariate analysis; there were 11 factors related to PEDV status at the P level less than 0.1. Only 3 of 11 risk factors remained in the multivariate regression model including a history of PED within 2 years; near residential areas and near to irrigation system were significantly associated with the spread of PEDV among small-scale pig farms (P <0.05).
