An early and unproven theory the couple was exposed to the virus because of vermin at a landfill in Ushuaia, a resort city they apparently visited for birdwatching before the ship departed, has spread wildly but Argentine officials say their visits did not align with the dates they are believed to have been infected or with places in the country the Andes variant of hantavirus is known to exist.
