The person was on board the MV Hondius, the center of the outbreak that has claimed three lives

Canadian officials said on Saturday that one of the four Canadians currently quarantining in British Columbia after being exposed to the hantavirus while on board the cruise ship where the outbreak occurred has presumptively tested positive.

Speaking at news conference, Dr Bonnie Henry, British Columbia’s provincial health officer, said the individual developed mild symptoms, including fever and headache, two days ago, and that the individual and their partner, who had also been on board the cruise ship where they had been isolating together, were transferred to a hospital in Victoria for assessment and testing.
