Clinical Signs

Acute Virus (Africa)

  • Nasal discharge, diarrhoea, reddening of the skin
  • Death within 7 days
  • PM: widespread internal hemorrhage

Subacute Virus (Europe)

  • Mortality: 30-70%
  • Survivors may lose body condition, have skin ulcers and joint swelling
  • PM: Petechial hemorrhages may be seen under kidney capsule

Epidemiology

  • Can persist on infected premises for months
  • Subacute recovered pigs become antibody-positive carriers
  • Transfer:
    • Africa: vertical transfer between soft ticks
    • Europe/Africa: direct contact with carrier pigs, aerosol, infected swill, etc.

Diagnosis

Control

  • No vaccine is available

Prevention:

  • Boiling swill
  • Isolation of sick pigs, domestic pigs from wild pigs
  • Keep pigs on concrete, not soil (to lessen tick contact)
