Initial reports indicate that this horse has traveled extensively within the province for both work and competition. No clinical signs of disease were noted at the time of sampling.
A CFIA investigation is underway and as per program policy, a quarantine has been placed on the infected animal and its on-premises contact animals. The quarantine will remain until all disease response activities have been completed, including follow-up testing and ordering the destruction of positive cases.
