In plain terms
The Polar-expedition cruise sector functions as an emergent biosecurity exposure substrate - tourists are funneled in massive numbers (IAATO data: 27,243 visitors 2014-15 to 118,491 in 2024-25, over 4× growth) through one primary gateway…
The Polar-expedition cruise sector functions as an emergent biosecurity exposure substrate - tourists are funneled in massive numbers (IAATO data: 27,243 visitors 2014-15 to 118,491 in 2024-25, over 4× growth) through one primary gateway port (Ushuaia, Argentina) that sits inside the endemic range of zoonotic pathogen reservoirs. Existing biosecurity protocols are one-directional: rigorous screening prevents humans from introducing invasive species INTO Antarctica, but no equivalent system catches tourists carrying zoonotic pathogens OUT of South American gateway ports into the global travel network. The MV Hondius Andes hantavirus cluster (April-May 2026) is the first verified outbreak event under this substrate.
