Argentina is experiencing a surge in hantavirus infections, with 101 cases reported since June 2025, nearly double the previous year, and a mortality rate tripling to about one-third of cases. This rise is linked to climate change, which is expanding the virus's range and allowing infected rodents to migrate. The country, where the MV Hondius cruise departed, consistently has the highest incidence of the disease in Latin America.

Argentina has reported 101 hantavirus infections since June 2025, a figure double that of the previous year, with the mortality rate nearly tripling to approximately one-third of cases. Rising temperatures and extreme weather patterns are contributing to the expansion of the virus's range, allowing infected rodents to migrate into previously unaffected regions across Argentina. Authorities are investigating if the country is the source of a deadly hantavirus outbreak on an Atlantic cruise ship.

The World Health Organization (WHO) revised the global total of hantavirus cases linked to the MV Hondius cruise ship down to 10 on May 15, 2026, after a U.S. passenger's inconclusive test was confirmed negative. U.S. health officials are monitoring 41 people, including 18 quarantined in Nebraska and Atlanta, for possible infection. The outbreak involves the Andes virus, a strain that has circulated in parts of Argentina and Chile for decades, with no significant viral changes identified to make it more transmissible or severe. The WHO stressed that the outbreak is not comparable to COVID-19 a
