Officials in Ushuaia address competing accounts about where a lethal hantavirus strain originated. Media reports say multiple official documents previously pointed to a landfill area and a nearby bird-watching site in the city as the “ground zero” for transmission. However, one source now says the story may not be accurate in the way it has been widely described. The report states that an official contends a specific Dutch couple did not contract the virus from the landfill site, challenging the earlier implication that the landfill and bird-watching location were the infection source for the cases being discussed. The same coverage notes that attention has shifted to a new location, which is now being examined as part of the investigation. Overall, the information indicates that authorities have produced reports linking the hantavirus to particular sites around Ushuaia, while later statements and additional scrutiny introduce uncertainty about which location directly led to infection in the reported cases. The dispute centers on the exact transmission source rather than the existence of hantavirus cases themselves.
