Porcine epidemic diarrhea virus (PEDV) emerged for the first time in Canada in Ontario swine herds in latex000D
January of 2014. Initial outbreak investigations and subsequent experiments identified porcine plasma as thex000D
most likely vector by which the virus was introduced into Ontario swine populations. The role of feed andx000D
other potential confounding factors in the emergence of PEDV in Canada has to be investigated andx000D
documented using sound epidemiological study design. The epidemiological study presented in this proposalx000D
aims to clearly document and determine aspects of risk associated with an Ontario swine farm becomingx000D
infected with PEDV using case-control and cohort epidemiological observational study approaches. The otherx000D
aspects of this study are to characterize the network structure and movement patterns between case and controlx000D
herds and to evaluate the utility and success of infection elimination strategies on PEDV case herds. Data forx000D
the study will be collected through many mechanisms i) detailed interviews with producers of case and controlx000D
herds (case-control study), ii) detailed interviews with producers of exposed and non-exposed herds (cohortx000D
study) , iii) diagnostic laboratory data, iv) interviews with Ontario swine herd veterinarians, and v) data derivedx000D
from industry-led PEDV control and elimination programs. The information gained from this study isx000D
important for the swine industry as it will inform industry wide biosecurity practices. Additionally, thex000D
information has the potential to be extrapolated and used to aid in the control of other infectious swinex000D
pathogens, and the results will inform the development of successful elimination strategies for herds thatx000D
become infected with PEDV now and in the future. This information will ultimately help Ontario andx000D
Canadian pork producers to remain competitive in the global pork market by protecting and promoting thex000D
health and welfare of the Canadian swine herd from PEDV and similar infectious pathogens.
