The Argentine health ministry on Tuesday reported 101 hantavirus infections since June 2025, roughly double to the year prior.
A hantavirus found in South America, called the Andes virus, can cause a severe and often fatal lung disease called hantavirus pulmonary syndrome. The disease led to death in nearly a third of cases in the last year, Argentina’s health ministry said.
Authorities said passengers on the MV Hondius ship tested positive for the Andes virus.
