Distinct from droplets by size (typically < 5 µm) and their ability to remain airborne for extended periods. Andes virus — Hantavirus strain present in South America (Argentina, Chile). The only hantavirus with documented human-to-human transmission. Leading cause of severe pulmonary syndrome. Case fatality rate — Proportion of deaths among people diagnosed with a disease. For hantavirus pulmonary syndrome: ~36% on average, up to 40% for Andes virus. CDC — US federal public health agency based in Atlanta. Global reference on hantavirus diseases since the identification of Sin Nombre virus in 1993. Contact case — A person exposed to a confirmed case under conditions likely to enable transmission. Subject to medical surveillance and, depending on risk, appropriate isolation. Contact tracing — Public health process of identifying, informing and following up people who have been in contact with a confirmed case of an infectious disease, to break transmission chains. ECDC — European Union agency based in Stockholm, tasked with identifying, assessing and communicating health threats in Europe. Coordinates the European response to the MV Hondius episode. ECMO — Extracorporeal membrane oxygenation. A life-support technique that oxygenates blood outside the body when the lungs (or the heart) can no longer do the job. Expedition cruise — Small-capacity cruise format (~100 to 200 passengers) for remote or polar destinations (Antarctica, Arctic, South Atlantic). The format the MV Hondius belongs to. Favipiravir — Broad-spectrum antiviral developed in Japan against influenza (Fujifilm Toyama, 2014). Now being explored against Andes hantavirus — efficacy not yet demonstrated. Genetic sequencing — Determining the exact nucleotide order of a viral genome. Used to identify variants, retrace transmission chains and compare strains. GPMB — Independent body of experts created by the WHO and the World Bank in 2018. Assesses every year the world's pandemic preparedness and publishes its findings without political filter. Hantavirus pulmonary syndrome — Severe clinical form of hantavirus infection, mainly caused by American strains (Andes virus, Sin Nombre). Case fatality rate of 30 to 40 percent. Hantavirus — Genus of segmented RNA viruses transmitted by wild rodents. In humans causes hantavirus pulmonary syndrome (Americas) or hemorrhagic fever with renal syndrome (Eurasia). Hemorrhagic fever with renal syndrome — Clinical form of Eurasian hantavirus diseases, primarily affecting the kidneys. Global incidence is 60,000 to 150,000 cases per year, the vast majority in China. Incubation period — Interval between exposure to a pathogen and the onset of the first symptoms. For Andes virus: 7 to 42 days, on average 18 to 24 days. Infodemic — An overabundance of information, accurate or false, accompanying a health crisis. A concept popularised by the WHO that hampers public access to reliable sources. MV Hondius — Polar expedition vessel operated by Oceanwide Expeditions, at the origin of the April-May 2026 Andes hantavirus cluster between Ushuaia and Tenerife (Granadilla de Abona). PCR — Polymerase chain reaction. Molecular method for detecting viral DNA or RNA. For hantaviruses: sensitivity ~92%, specificity 100%, result in a few hours. Human-to-human transmission — Passage of an infectious agent from one human to another. For hantaviruses, only documented with Andes virus; requires close, prolonged contact with a symptomatic person. Personal protective equipment — Equipment worn to limit exposure to an infectious agent. Includes filtering masks (FFP2/N95), gloves, gowns and goggles. FFP2 filters at least 94% of particles under EN 149. PREP Act — US federal law (2005) granting liability immunity for the development and deployment of medical countermeasures during a declared public health emergency. Rodent reservoirs — Wild rodent species that chronically carry a hantavirus without apparent symptoms. The Andes virus reservoir is the rodent Oligoryzomys longicaudatus (colilargo) in Patagonia. Santé publique France — The French national public health agency, created in 2016. Surveillance, alert and intervention on health threats facing the French population. Vaccine — A preparation that trains the immune system to recognise a pathogen. Against Andes hantavirus, no vaccine is licensed to date. Viral variant — A strain of a virus carrying one or more mutations in its genome compared with reference strains. Most are neutral; some change transmissibility, virulence or treatment resistance. WHO — United Nations specialised agency responsible for global public health. Coordinates the international response to outbreaks via the International Health Regulations. Zoonosis — Infectious disease naturally transmissible between vertebrates and humans. 60 percent of emerging infectious diseases are of animal origin; hantavirus diseases are among them.
