Foreign Animal Disease Surveillance Project
About FADS
An outbreak of a highly contagious foreign animal disease (FAD)
has the potential to cripple the animal agriculture industry of the
United States. Surveillance systems currently employed for
detection of FADs rely heavily on recognition of such diseases by
producers and private veterinary practitioners. Methods of active
surveillance are necessary to guarantee rapid detection of an FAD
incursion to prevent the devastating economic and social
consequences of delayed recognition. The field use of new
diagnostic assays developed for the recognition of high consequence
pathogens have yet to be clearly defined and evaluated. This gap in
knowledge prevents government agencies from making informed
decisions concerning mitigation strategies as related to FAD
surveillance.
The creation of a practitioner network involved in the active
surveillance of cattle with undifferentiated illness will help
prevent catastrophic disease epidemics that could result from the
intentional or accidental introduction of an FAD. Routine
surveillance by veterinary practitioners examining ill livestock
with vague clinical presentations may allow earlier detection of an
FAD before an explosive epidemic occurs. Screening cattle for FADs
at markets (as brucellosis) would increase the probability of
earlier detection. Prevention is the key to all disease control
programs, whether they are FADs or naturally-occurring endemic
conditions. A well-trained network of private veterinary
practitioners routinely submitting diagnostic specimens for
screening would be an effective tool for prevention. This research
program will also develop the statistical tools necessary to
optimize decision rules for the initiation of FAD outbreak
investigations, based on results of imperfect screening tests.
