Argentina has said it is expanding its probe into the origins of the hantavirus outbreak that struck an Atlantic cruise vessel past month, sending scientists to trap and trial rats successful the occidental state of Mendoza portion laboratory results are pending from the southernmost metropolis of Ushuaia.
Argentine authorities said biologists from the United States Centers for Disease Control and Prevention (CDC) were joining the ngo adjacent week successful Mendoza.
The uncommon outbreak connected the MV Hondius was caused by the Andes hantavirus, a illness carried by rodents endemic to Argentina and Chile and the lone hantavirus thought to beryllium capable to dispersed betwixt radical successful immoderate cases.
Reconstructing the concatenation of transmission is hard work, and Argentine authorities accidental it whitethorn ne'er beryllium imaginable to pinpoint precisely wherever the archetypal known victims — a Dutch mates who died successful April — contracted the microorganism earlier boarding the cruise successful Ushuaia.
But experts accidental getting to the bottommost of the outbreak volition connection invaluable accusation astir however the uncommon microorganism dispersed and transportation important lessons for absorption of the disease.
As repatriated cruise passengers from much than 20 countries person disembarked and entered specialised quarantine centres, epidemiologists are examining the 11 confirmed hantavirus cases, including the schedules of the 3 radical killed, to amended recognize the concatenation of transmission.
Argentine scientists are moving to retrace the way of the Dutch tourists, believing that the archetypal root of the onboard microorganism to beryllium the man's vulnerability to rodent droppings oregon urine during their monthslong travel crossed Argentina and Chile earlier the ship's departure. The emblematic incubation play earlier symptoms look is astir 3 weeks but tin widen up to eight.
Shortly aft quality of the outbreak emerged, Argentina's Health Ministry identified Ushuaia arsenic a imaginable root of the contagion and past period sent investigators from the Malbran authorities probe institute to cod rodent samples successful assorted wooded areas astir the city.
Local authorities successful the tourism-dependent metropolis of Ushuaia, famed for its determination astatine “the extremity of the world”, person angrily disputed that the microorganism originated there. While the Andes hantavirus infects a fewer twelve radical each twelvemonth successful the Patagonian portion of Argentina further north, it has ne'er been detected successful Ushuaia oregon the wider archipelago of Tierra del Fuego.
The Health Ministry said connected Friday (June 5, 2026) that it's inactive awaiting laboratory results from those tests to find whether the mates contracted the microorganism there.
On Friday (June 5, 2026), the Ministry said specialists from Malbran, unneurotic with U.S. counterparts astatine the CDC, were preparing to trial rodents for the hantavirus successful the metropolis of Malargüe, Mendoza from June 8-12.
A spokesperson for the Malbran Institute confirmed that the Dutch mates visited Malargüe arsenic they drove done the winemaking portion of Mendoza to the northeastern state of Misiones during the past limb of their travel successful Argentina.
The caput of Malbran, Claudia Perandones, met with CDC investigators successful Argentina connected Friday (June 5, 2026) to sermon the operation, which she said would impact teams successful extended protective instrumentality taking humor samples from dormant rodents and transferring the worldly to the main laboratory successful Buenos Aires for testing. Authorities person said trial results could instrumentality up to a month.
The World Health Organization (WHO) has made wide that, fixed the debased hazard of transmission, the hantavirus volition not go a pandemic threat. Still, the Andes hantavirus has raised concerns astir the satellite owed to its mortality rate, arsenic precocious arsenic 30%, and the existent deficiency of attraction and vaccines.
