If vaccination is continued for a few more years and the downward trend continues, the stage will be set for the eradication phase. Unfortunately, this is unlikely to be achieved in the foreseeable future unless movements from Angola can be controlled. This leaves only the option of implementing the same strategy in Angola and other affected countries with the aim of eradicating the disease on a regional basis. The number of CBPP foci reported from the different regions are shown in the map below. Although the current disease trend is very encouraging, it must be viewed with caution because the disease data are based on passive surveillance.
Active surveillance is required to make a better assessment of the disease status.
This requires accurate identification of individual herds, sources of infection, traceability of origins of infections and all contact herds. Cases detected at the abattoir must also be traceable. The recent introduction of individual brands in infected areas will help in this regard. Abattoir data Valuable data can be obtained from examining lungs at slaughter. In the case of high-risk regions, animals go through quarantine before slaughter, thus eliminating visibly infected animals.
