Analysis of present day spread of classical swine fever in the world

Abstract

The purpose. To study epizootic situation concerning classical swine fever (CSF) in the world in 2012-2017 and to determine major factors which can promote spread of infection to Ukraine. Methods. Data of official veterinary statistics, materials of scientific publications and Internet-resource WOAH (http://www.oie.int) are used. Reports from 243 countries of the world including Europe (55), Asia (46), Africa (59), America (52) and Oceania (31) are analyzed. Results. It is established that for the last 6 years CSF flashes were registered in 30 countries (12,3%) of 243 analyzed; in 92 countries (37,9%) there were no revealed flashes of disease for the accounting period; 57 countries (23,5%) did not give information on CSF; and in 64 countries (26,3%) CSF had never registered. The greatest amount of CSF flashes was registered in countries of Asia (15), Central and South America (8), a little bit less in East Europe (3) and Africa. According to WOAH countries of Northern America, Europe (22), Australia, New Zealand, New Caledonia and Japan are officially recognized as CSF free. In Ukraine epizootic CSF was liquidated in 1997, however sporadic events of disease among wild boars still occur. Major factors which can lead to spread of CSF to our country include: migration of wild boars and their contact to house pigs, international trade, and also vaccination against CSF. Key tool of monitoring and prevention of emersion of new CSF flashes is duly and effective diagnostics. Conclusions. During 2012-2017 CSF flashes were registered in 30 countries, in particular in territory of Asia, Central and South America, and also East Europe and Africa. Northern America, the most part of Europe (22), Australia, New Zealand, New Caledonia and Japan are officially recognized as CSF free. Epizootic situation on CSF in Ukraine is concerning stable. For the last 6 years only one CSF flash had been registered among wild boars. However there is a high risk of repetitive occurrence of the disease.
