Scientists Deploy to Ushuaia for Hantavirus Investigation

A team of scientists from Argentina's ANLIS-Malbrán Institute is scheduled to travel to Ushuaia next week to investigate the potential presence of hantavirus in the region. This fact-finding mission follows a rare outbreak aboard the MV Hondius cruise ship, which departed from Ushuaia on April 1 and resulted in three fatalities. While local health authorities doubt that passengers were infected in Ushuaia due to the virus's incubation period and the absence of historical cases in Tierra del Fuego, the probe aims to definitively determine if the local rodent vector exists there. Provincial health official Juan Petrina stated that results are expected within four weeks. The World Health Organization suggests the initial infection likely occurred before the voyage, with subsequent human-to-human transmission on board. The Andes strain, carried by the long-tailed pygmy rice rat, has been identified as the cause. No vaccines or specific treatments exist for this respiratory disease, which remains endemic in other parts of Argentina but has never been recorded in this southern province.
