Introduction

African Swine Fever ocurs after infection by the Asfarviridae family of viruses. ASF is a serious exotic virus that should not be confused with Classical Swine Fever.

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

The virus can persist on infected premises for months. Subacute recovered pigs become antibody-positive carriers.

  • Viral transfer occurs as follows:
    • Africa: vertical transfer between soft ticks
    • Europe/Africa: direct contact with carrier pigs, aerosol, infected swill, etc.

Diagnosis

Control

No vaccine is available.

Prevention control measures include:

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