Systematic review of transmission factors, management interventions, and elimination techniques related to porcine epidemic diarrhea

National PEDV eradication may not be feasible, but improved biosecurity, feed decontamination, and surveillance can reduce transmission and losses. Vaccines can help control disease but do not provide complete immunity, and other complementary control strategies are required for an industry-level control program. Future research should focus on improving biosecurity compliance, information-sharing during outbreaks, and epidemiological modelling to understand the role of vaccines during an eradication program.
