In a recent health update, officials in Canada reported a presumptive positive test result for hantavirus in one of four Canadians under quarantine in British Columbia. The individuals had been exposed to the virus on the MV Hondius cruise ship. Dr. Bonnie Henry, British Columbia’s provincial health officer, shared that the affected person experienced mild symptoms such as fever and headache. Both the individual and their partner, who were on the cruise, have been hospitalized in Victoria for further evaluation and testing.
Dr. Henry announced that the test results, which came in late Friday, indicated a presumptive positive for the virus. To ensure accuracy, the samples have been forwarded to the national microbiology lab in Winnipeg for confirmation, with results expected over the weekend. Despite the unexpected development, Dr. Henry assured that the situation was anticipated and planned for, emphasizing that the patient remained stable with only mild symptoms. The patient’s partner tested negative but will remain in the hospital for ongoing observation.
As a precaution, a third person from the same quarantine lodging has also been moved to the hospital for monitoring. Meanwhile, the fourth individual continues their isolation at home under daily observation. The four Canadians involved had arrived in Victoria on May 10, after which they were quarantined for a minimum of 21 days despite being symptom-free upon arrival.
In related developments, the Pasteur Institute in France has completed the full sequencing of the Andes virus found in a French passenger from the cruise. The analysis revealed that the virus closely matches strains already identified in South America, showing no new traits that could increase its transmissibility or danger. The genomic study confirmed that the virus from the ship’s cases was nearly identical to known Andes virus samples circulating in South America, with natural viral variation not affecting the virus’s characteristics.
Since April 11, the hantavirus outbreak on the MV Hondius has led to the deaths of three passengers, including a Dutch couple and a German woman. The Canadian and international health authorities continue to monitor the situation closely to prevent further spread and manage the health of affected individuals.
