Overview and epidemiology of contagious bovine pleuropneumonia in Africa.
Contagious bovine pleuropneumonia (CBPP) is widespread in Africa and in other regions of the world. This disease is particularly important in the semi-arid, sub-humid and arid zones of tropical Africa, but CBPP incidence seems to be increasing in some parts of East Africa. The epidemiology of CBPP is characterised by the occurrence of sub-acute and symptomless infections, and the persistence of chronic carriers. Spread of the disease is associated with cattle movement. The major obstacles to eradication of CBPP are the difficulties in controlling cattle movement and applying quarantine and slaughter policies. Other difficulties arise due to the absence of a field test for diagnosis, the relatively short duration of post-vaccinal immunity and the lack of data on the economic impact of the disease. The Pan-African Rinderpest Campaign strategy for CBPP control and eradication conforms with national control programmes, which include cost/benefit analysis. It is planned to perform blanket vaccination against the disease for three to five years, depending on the economic situation of each country. Stringent control of cattle movement will complement vaccination campaigns. The eradication phase, including slaughter measures, will be instituted following reduction of CBPP incidence. Regional and international coordination will be instituted to control international cattle movement and harmonise control strategies.
