B. Active surveillance

epidemiological

Levels of advancement

  • 1.

    The VS have no active surveillance programme.

  • 2.

    The VS conduct active surveillance for some relevant

diseases (of economic and zoonotic importance) but apply it only in a part of susceptible populations and/or do not update it regularly. 3. The VS conduct active surveillance for some relevant diseases and apply it to all susceptible populations but do not update it regularly. 4. The VS conduct active surveillance for some relevant diseases, apply it to all susceptible populations, update it

regularly and report the results systematically.

5.

The VS conduct active surveillance for most or all

relevant diseases and apply it to all susceptible populations. The surveillance programmes are evaluated and meet the

country’s OIE obligations.

Results Strengths : See point II.5.A Weaknesses : Most of the field work is done by trained Animal Health Technicians and not by veterinarians Personnel vacancies and budgetary deficiencies in the laboratory negatively impact the capability to conduct extensive surveillance programs Supporting documentation (documents or photos): See point II.5.A Detailed findings during visit: Animal health inspections: The animal health inspections of the farms within the territory of a SVO are done by the SVOs and a certain percentage by AHTs, while the information from all other farms is provided directly by the farmers in the form of a questionnaire. The farm visits are selected at random or when information in the questionnaire determines it. Farms are suspended from being able to move animals (farm is closed) when the farmer is negligent in providing the questionnaire or fails to return the animal movement permits within the established time period.

Active surveillance is conducted by the VS, not only on diseases of importance for exports. They have extensive programs on surveillance for FMD (in the buffer, surveillance and free zones), CBPP, rabies, anthrax, lumpy skin disease, MCF, pasteurellosis, tuberculosis and brucellosis, as well as residue testing and feed sampling for bovine proteins. The surveillance in poultry is limited due to the small number of poultry in the country. Low and highly pathogenic Avian influenza has not been reported, although there is an occasional report of Newcastle disease.
