The objective of this advice is to identify the risk factors of emergence of infectious animal diseases in Belgium to allow the risk managers to undertake control measures in time. For that purpose, 34 examples of (re)-emerging or at risk of (re)-emergence infectious animal diseases and 33 risk (or protection) factors of emergence were selected aiming for the most complete representativeness as possible. The effect of these factors on the risk of emergence of the 34 animal diseases was analysed via a Delphi survey by 50 experts. The study allowed to rank the risk factors according to their relevance to the emergence of separate groups of infectious animal diseases (for example, exotic, zoonotic, foodborne diseases, etc.), as well as for all the diseases, taken together in one global group. The six most important risk factors, when considering (re)-emerging animal diseases as one global group, are the following: presence of an animal reservoir, detection problems of emergence of disease, difficulties to ... : BE; nl; secretariaat.scicom@favv-afsca.be ...
