    ARGENTINA: 150 box traps set in forests around Ushuaia — colilargo rat hunt for hantavirus source

    Argentine scientists set 150 box traps in forests surrounding Ushuaia on May 19, targeting the colilargo rat subspecies (known hantavirus reservoir) in two areas: Tierra del Fuego National Park and wooded hillsides above the main beach. Dead rodents are being transported to a makeshift field lab for blood sampling, then sent to the Malbrán Institute in Buenos Aires for Andes virus testing. Results expected in up to one month. The province of Tierra del Fuego has never previously recorded hantavirus in wild rodents. Provincial spokesperson Martín Alfaro: 'The province has never done this kind of testing before. It's important that we rule out the possibility of transmission occurring here.' Government and provincial authorities disagree on whether the couple visited the landfill during the infection window.
