In a recent development from British Columbia, Canadian authorities have reported a presumptive positive test result for hantavirus in one of the four Canadians currently in quarantine. The individuals had been exposed to the virus aboard the MV Hondius cruise ship, which recently experienced an outbreak. Dr. Bonnie Henry, the provincial health officer for British Columbia, shared that the affected individual exhibited mild symptoms like fever and headache two days prior and is currently hospitalized in Victoria for further evaluation and testing.
Dr. Henry elaborated that the presumptive positive results for the individual were received late Friday night. She emphasized that these results are preliminary and have been forwarded to the national microbiology lab in Winnipeg for confirmation, with expected results over the weekend. She reassured the public that although the outcome is not ideal, it aligns with the planned response measures. The patient remains stable, with mild symptoms, and is under isolation in the hospital, receiving necessary care.
While the patient’s partner, who was also on the cruise, tested negative, they have been admitted to the hospital for additional monitoring. In a precautionary move, a third person who had been staying with them in the same lodging has also been hospitalized for observation. Meanwhile, the fourth Canadian continues to observe quarantine protocols at home, under daily health checks. The group had arrived in Victoria on May 10, with initial assessments showing no symptoms, and were subsequently placed under a mandatory 21-day quarantine period.
On an international note, France’s Pasteur Institute has successfully sequenced the Andes virus from a French passenger on the MV Hondius. The analysis revealed that the virus closely aligns with other known strains in South America, showing no new traits that might increase its transmissibility or severity. The genomic study indicated a 97% similarity with Andes virus samples found in South American rodents, and the remaining variations were attributed to natural viral changes, without impacting the virus’s characteristics among passengers.
Tragically, since April 11, three individuals from the cruise have passed away from suspected hantavirus infections, including a Dutch couple and a German woman. These developments underscore the ongoing health monitoring and response efforts following the outbreak on the MV Hondius.
