Authorities are also tracing the movements of a couple who died after an outbreak on the MV Hondius cruise ship, which departed from Ushuaia. The Andes strain, capable of human-to-human transmission, is linked to the outbreak. Four geographic regions of Argentina are historically high-risk areas for c
