90-Second Read: Hantavirus latest updates: Canada reports first presumptive case linked to MV Hondius as global total hits 11

There are no known cases of Hantavirus in the United States, health officials say. Dozens of people are being monitored for Hantavirus tied to the deadly outbreak on board the cruise ship MV Hondius. The case total has climbed to 11, the BBC reported Sunday, after a Canadian passenger from the ship tested presumptive positive for the virus. Three people who traveled on the ship have died, two of them confirmed to have had Hantavirus.

In Colorado, the state health department said Saturday that a Douglas County adult had died of Hantavirus in a case that is also not linked to the cruise ship. The Colorado case involves the Sin Nombre strain, not the Andes strain circulating on the MV Hondius, and is the kind of infection state officials say turns up nearly every spring and summer. From 1993 through 2023, Colorado reported 121 Hantavirus cases to the CDC. The two most recent arrivals had been at Emory University Hospital in Atlanta and were transferred to Nebraska on Friday after being medically cleared.

Six Canadians traveled on the MV Hondius; none of the other five have tested positive. WHO Director-General Tedros Adhanom Ghebreyesus has said the risk to the global population remains low. One of them had been admitted to Emory's biocontainment unit with mild symptoms but tested negative; the other was a close contact who was asymptomatic. The Colorado Department of Public Health and Environment said preliminary evidence points to local exposure to rodents, and that the strain involved, Sin Nombre, does not spread person-to-person.
