Rare human-to-human hantavirus transmission suspected on cruise ship

A WHO briefing says MV Hondius passengers may have contracted hantavirus through rare human-to-human transmission, with two confirmed cases, five suspected, and three deaths as about 150 passengers remain quarantined while scientists work to identify the virus strain (likely Andes) and trace transmission routes; hantaviruses usually spread via rodents, and human-to-human spread is extraordinarily rare and requires close contact, with an incubation of 2–8 weeks and no cure beyond supportive care.
