Officials from Argentina are investigating the likely source of a hantavirus outbreak aboard the MV Hondius cruise ship. Multiple reports say the inquiry centers on whether exposure could have occurred during a pre-boarding visit by a couple who went birdwatching at a landfill site in South America before they boarded the vessel. The officials involved in tracing the outbreak’s origins state the landfill visit is one possible lead, based on information gathered during the investigation. The reports frame the landfill trip as a potential link rather than a confirmed cause. Both outlets agree that investigators are looking at the couple’s activities as part of determining how the infection was contracted and brought onto the ship. The reports do not specify the date of the birdwatching trip, the exact landfill location, or whether other passengers may have had similar exposure. The investigation is ongoing, with authorities continuing to examine timelines, travel details, and potential contacts tied to the couple and the landfill environment.
