Abstract
African swine fever (ASF) and classical swine fever (CSF) are transboundary animal diseases
(TADs) of pigs. Much effort and resources are regularly put into preventing these diseases’
introduction in free areas. Passive surveillance activities bring the highest chances for the
early detection of TAD incursions because they are routinely Rev Sci Tech, 41 (2) 2 41_2_16_
Schettino_preprint 2/30 and widely conducted at the farm, and because these activities focus
on the time between introduction and the time the first sample is sent for diagnostic testing.
Here, we proposed the implementation of an enhanced passive surveillance (EPS) protocol
based on collecting data through participatory surveillance actions using an objective and
adaptable scoring system to aid the early detection of ASF or CSF at the farm level. The
protocol was applied in two commercial pig farms for ten weeks in the Dominican Republic,
which is a CSF- and ASFinfected country. This study was a proof of concept, based on the
EPS protocol to aid detection of substantial variations in the risk score triggering testing. One
of the followed farms had score variation, whichtriggered testing of the animals, although
the test results were negative. The study help assess some of the weaknesses and learn lessons applicable to the problem. Results demonstrate the potential for overcoming some issues preventing the broad application of EPS protocols and suggest that standardised approaches may contribute to the early detection of CSF and ASF introductions.
