This is sounding a lot less like norovirus.

Elizabeth Church of Toronto’s Globe and Mail reports that for the fifth time in less than a week, a Canadian airline is reporting several ill passengers on a flight returning from the vacation destination of Holguin in Cuba.

Although many travellers on each flight reported staying at the same resorts, at least four resorts have been identified amongst the travellers onboard the first four affected flights, according to the Public Health Agency of Canada.

But those resorts could have the same food suppliers; and at least one commenter to barfblog.com said he or she was tested upon arriving in Canada and tested positive for salmonella.

Michelle Larabie said she got sick on a plane returning to Toronto from Holguin on Jan. 13, a week earlier than the other flights. She said she began feeling nauseous while in the air, and her sickness and diarrhea lasted nearly a week.
