The authors represent different institutions, authorities or universities in European Union member states. Arvo Viltrop represents an ASF affected country, Estonia, Vittorio Guberti represents Italy that has been affected by ASF on the island of Sardinia for more than 35 years. Erika Chenais, Karl Ståhl, Klaus Depner and Klaas Dietze represent unaffected countries at risk for introduction (Sweden and Germany). All the authors have special interest in, and research experience from, different aspects of African swine fever.
Understanding humans – the key to African swine fever control
For more than ten years African swine fever (ASF) has been spreading in Eurasia, currently expanding its territory both west- and eastwards. The disease affects domestic pigs and wild boar: animals usually die within three to ten days after infection and the case fatality rate can be almost 100%. Disease impacts are enormous, relating to the welfare of domestic pigs and wild boar, and negative economic consequences for individual pig farmers, the pig industry, the hunting sector, regions, nations and common trade areas. A review published in Porcine Health and Management presents recent developments in the epidemiological understanding of African swine fever, based on the current epidemic in Europe and Asia.
The 4 epidemiologic cycles of African swine fever. 1) Sylvatic cycle: the common warthog, bushpig, and soft ticks of Ornithodoros spp. 2) The tick–pig cycle: soft ticks and domestic pigs. 3) The domestic cycle: domestic pigs and pig-derived products (pork, blood, fat, lard, bones, bone marrow, hides). 4) The wild boar–habitat cycle: wild boar, pig- and wild boar–derived products and carcasses, and the habitat.
