Portrait of the national veterinary service as a surveillance continuum

In anticipation of, or in response to, these myriad challenges, national veterinary services mount surveillance campaigns. From the national survey that denies the presence of exogenous disease to the post-eradication assessment that confirms its demise, surveillance forms the sensory acumen of the service. From the passive assessments that detect the emerging to the active regimens that plot progress against the indigenous, they form a continuum that defines the very nature of the national veterinary service.
