The current brucellosis control program in small ruminants consists in two major components the first is an intervention strategy through modification of host resistance by vaccinating the entire small ruminant’s population using live attenuated Rev-1 strain of B. melitensis.  The second is a post vaccination monitoring and surveillance system (MOSS) to monitor the efficacy of the mass vaccination. The MOSS is based on sampling vaccinated animals between 20 to 40 days post-vaccination and testing through Rose Bengal Plate Test in order to detect antibody presence and evaluate the vaccination sero-conversion and coverage. Rose Bengal test is recommended for screening of samples to determine flock prevalence and like other serological tests it cannot discriminate between natural infection and vaccination antibodies. The methodology used in the post vaccination MOSS during the mass vaccination campaigns of 2012 and 2013 demonstrated much strength upon which future MOSS should be built. However, the current system has also shown gaps in terms of missed opportunities to analyse information generated from other sources. Trends of disease in accidental hosts like humans have not been integrated within post vaccination MOSS. Given that the infection level cannot be estimated in small ruminants, data generated by public health surveillance system can be able to give an independent overview of the impact of the vaccination campaign. This paper will address in depth this issue by showcasing the value of integrated surveillance data in monitoring the success of brucellosis control measures in small ruminants as a one health approach in practise.
