The Country Where Lethal Hantavirus Cases Are on the Rise. Experts Blame Climate Change

Authorities say the season has brought 101 confirmed cases and 32 deaths, while investigators trace a cruise ship outbreak linked to the Andes strain.

  • Argentina's Health Ministry reported 101 confirmed hantavirus cases this season, compared to 57 last year, as authorities investigate a separate outbreak on the cruise ship MV Hondius that departed Ushuaia on April 1.
  • Climate change and habitat destruction are fueling the trend, according to experts, as environmental degradation allows virus-carrying rodents to thrive in new areas outside historically endemic regions.
  • Citing records, Juan Petrina, director of epidemiology for Tierra del Fuego, stated the timeline "doesn't add up for them to have contracted the disease here," as the couple visited Ushuaia only from March 29 to April 1.
  • Technical health teams are deploying to Ushuaia to analyze local rodents, while Buenos Aires province reported the highest infection count this season with 42 cases concentrated in the central region.
  • Lethality rates have increased by 10 percentage points over the previous year, marking a more severe situation than the 2018 Patagonia outbreak, which killed 11 people and resulted in dozens of infections.
