Disease Monitoring (Surveillance) Concerns
Normal appearing animals can spread the disease
Shed the virus 2 to 4 days before clinical signs appear
Biosecurity is critical
Shedding of FMD virus

ASF and CSF may resemble other swine diseases
• Porcine dermatitis and nephropathy syndrome (PDNS)
• Postweaningmultisystemic wasting syndrome (PMWS)
• Porcine reproductive and respiratory syndrome (PRRS)
• Aujeszky’s Disease (PRV)
• Erysipelas• Salmonellosis• Pasteurellosis• Actinobacillosis• Haemophilus suis
Close Observation
Diagnostic Testing
