| The evaluation of animal health surveillance will allow to identify the actions required to improve \\ the system (either passive or active components or both) and increase the number of cases detected and report.\\ Of course a part of non-detected cases will always remain.\\ \\ | The evaluation of animal health surveillance will allow to identify the actions required to improve \\ the system (either passive or active components or both) and increase the number of cases detected and report.\\ Of course a part of non-detected cases will always remain.\\ \\ | ||
