A Canadian who sailed on the cruise ship MV Hondius which was hit by a hantavirus outbreak in April has tested positive for the disease, officials in the province of British Columbia say. The individual, one of four people isolating on Vancouver Island after leaving the ship, had developed mild symptoms. The province's senior health officer said the four had not had any contact with the public since arriving in Canada. The case brings the total number of infections to 11, all among cruise passengers. Three people who travelled on the ship have died, with two confirmed to have had the virus. British Columbia health officer Bonnie Henry said the person's test came back as a presumptive positive on Friday, meaning that it still remains to be confirmed by a national microbiology lab. 'Clearly, this is not what we hoped for, but it is what we planned for,' she said, quoted by national broadcaster CBC. Dr. Henry reassured that hantavirus is significantly different from other respiratory viruses, emphasizing that it does not pose the same pandemic potential. Of the six Canadians who were on the ship, two are self-isolating in Ontario, while two couples remain on Vancouver Island, including the individual who tested positive. The cruise ship set sail from Argentina on April 1, docking in Tenerife, Spain less than a week ago. Following this outbreak, the remaining passengers have gone into isolation. The WHO has recommended a 42-day isolation period, although the initial expectation was 21 days. Hantaviruses are primarily carried by rodents and human transmission is possible. Symptoms include fever, fatigue, muscle aches, and stomach issues, with officials noting a low risk for a major outbreak.
