The zone spans across a portion of Oxford County and Waterloo County, Ontario. Infected premises ONT-2015-NAI-003 is located in Oxford County within the second AICZ. All premises located within the AICZ have been placed under quarantine. The CFIA is monitoring these premises closely for any signs of disease.
