The fifth, which Premier Marshall noted as "far more worrying", visited The Greek on Halifax restaurant at the same time as someone who was later confirmed to be carrying the virus. Chief Public Health Officer for the state Nicola Spurrier said "if anyone has been at The Greek on Halifax they need to get into quarantine and get tested".
