Epidemiological situation of transboundary animal diseases in North African countries-proposition of a regional control strategy.

The Food and Agricultural Organization (FAO) defined transboundary animal diseases (TADs) as those that are of significant economic, trade, and food security importance for a considerable number of countries. TADs can easily spread to other countries, reach epidemic proportions, and where control, management, or exclusion is required cooperation between several countries. The North African countries are vulnerable to several TADs by virtue of its geographical location, its borders with the Sahel region, and peculiar control constraints on the budgets of the national veterinary services of each country and on the livelihoods of livestock owners across the region. In a narrative approach, we comprehensively described the epidemiology of TADs in North African countries, eradication constraints and control measures adopted to conclude with a proposition of a regional control strategy. Our review uncovered foot-and-mouth disease, peste des petites ruminants, bluetongue, sheep/goats pox, brucellosis, West Nile and Rift Valley fever, as the major TADs in this region, while the major constraints identified were illegal animal movement, communal clashes, unreported outbreaks, poor vaccination coverage, and other factors peculiar to each etiology. Therefore, the establishment of early warning systems and proper implementation of control measures at regional level are highly recommended to the relevant stakeholders involved in TADs control in the region.
