ASF is a highlycontagious hemorrhagic disease that affects both domestic and wild pigs. This OIE-notifiable disease isconsidered one of the most important transboundary illnesses in pigs. For many years ASF hasremained endemic in Sardinia and Southern Africa. However, only a few years ago it was re-introducedin Europe once again through the Caucasus.• Generalized hemorrhagesFig 1. Countries where ASF is present (red, rose, purple). Fig 2. ASFV main transmission routes: sylvatic cycle, domestic cycle, through contaminated pork products and fomites.Fig 3. ASFV morphology.Fig 4. Macrophages infected with ASFV.Fig 5. Acute petechiae in the kidney.Fig 6. Positive HAD “rosette” test.ASFV has an important social and economic impact in the swine industry. Its potential to rapidly spread and produce long-termpersistent infection threatens many ASF-free European and Asian countries. Up to now, stamping out policies are the only measureable to control this disease, but they are ethically and financially difficult to accept. For this reason, the future control andelimination of ASFV occurrence depends on the development of an effective and safe DIVA vaccine .
