Health authorities continue to investigate. Onset of illness was on March 1 and rash appeared on March 6. The case may also have visited Saskatchewan during incubation period. The illness was characterized by vomiting and diarrhea and lasted no more than 48 hours. One week later, several Canadians travelling on the same charter flight became ill after arriving in Antigua.
Laboratory investigations are ongoing.

The flight kitchen in Toronto serving this particular charter airline and several other airlines has been inspected by federal public health officials and hygienic precautions have been reinforced.
