Hantavirus Outbreak on MV Hondius

An outbreak of Andes virus, a hantavirus capable of human-to-human transmission, occurred on the MV Hondius cruise ship. Ten individuals with connections to the ship or related flights have returned to Canada and are undergoing isolation and monitoring in various provinces including Canada — British Columbia, Canada — Ontario, Canada — Alberta, and Canada — Quebec. The Canada — Public Health Agency of Canada has implemented temporary travel restrictions for those aboard the MV Hondius. Public health officials, including Dr. Bonnie Henry and David Safronetz, are managing the situation, noting the long incubation period of the virus and challenges in testing asymptomatic individuals. The World Health Organization has provided guidance on quarantine periods. Scientists at institutions like the University of Saskatchewan are in early stages of developing a hantavirus vaccine, but no direct antiviral treatment currently exists for hantavirus pulmonary syndrome, which has a 30% mortality rate.
