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
