Three passengers have died and five have been confirmed with hantavirus aboard the MV Hondius, a Dutch cruise ship. The outbreak involves the Andes virus, which can be transmitted between people and is endemic to Argentina, where the cruise began. The World Health Organization (WHO) has stated that the public risk remains low, emphasizing that this is not a repeat of the COVID-19 pandemic. Investigations are ongoing to determine how the virus spread, particularly as the maritime setting is unusual for hantavirus outbreaks. Symptoms can take one to eight weeks to appear, complicating the tracing of contacts. Preventive measures against hantavirus include sealing entry points to homes, securely storing food, and using protective gear when cleaning areas potentially contaminated with rodent droppings. Health officials in South Africa are tracing individuals who may have encountered infected passengers, with 62 potential contacts identified. The cruise ship is now heading to Tenerife, where passengers will be quarantined based on their health status.
