Interior Health Authority officials say a downtown Kamloops (that’s in Canada) restaurant was the source of Norovirus that struck more than three-dozen staff at Royal Inland Hospital last week.

Medical Health Officer Dr. Rob Parker says the staff became sick after attending a party catered by Dorian Greek House.

Parker adds despite precautionary measures and extra cleaning undertaken by Dorian’s — a second party hosted by the restaurant Friday has resulted in another group of patrons falling ill Sunday.

Parker says Dorian has been closed temporarily while it hires a company to give the restaurant a full cleaning.
