A Canadian passenger from the MV Hondius, one of four Canadians who were quarantining in British Columbia, has tested "presumptive positive" for Andes Hantavirus, according to government officials. So far no cases have been identified in anyone other than passengers on the Dutch cruise ship. Public health staff from the Centers for Disease Control and Prevention will meet passengers in Tenerife, Spain as they deboard a cruise ship that has been at the center of a Hantavirus outbreak.
The case count from the Dutch cruise outbreak remains at 11 cases, including three fatalities. Late last week, the case count had been reduced to 10 cases after an American with an inconclusive test had been ruled out as having the virus, which is spread via inhaling rodent droppings or, rarely, from person to person. Currently, 41 Americans are still being monitored for up to 42 days for the virus, which can have a long incubation period.
Among those who debarked yesterday are 18 Americans, 1 of whom has tested positive for the virus. A case previously labeled as inconclusive has tested negative, WHO officials said. The person was transported to hospital for assessment and care on May 14 along with their spouse who also has mild symptoms.
