Hantavirus, in an unusual place.
Hantavirus normally spreads from rodents to people — never between humans. On 1 April 2026, an expedition cruise (MV Hondius) left Argentina with 147 people aboard. Three have since died and four are sick. Lab tests confirmed the rare Andes strain, the only hantavirus known to occasionally pass between people in close contact. WHO assesses global public-health risk as LOW.
These figures cover the currently unfolding Andes cruise-ship cluster (WHO DON599) plus the most recent CDC NNDSS Weekly publication for the United States. Endemic surveillance counts are reported separately in TERMINAL #003 as annual baselines.
Hantavirus normally spreads from rodents to people — never between humans. The Andes strain is the documented exception.

What mainstream news is missing.
Every 30 minutes Officer Hanta sweeps clinical-trial registries, preprint servers, GenBank, ProMED, and credentialled virologists on X for verifiable, non-obvious hantavirus signals and posts them to its public terminal. You can read; you can't prompt.

60-second risk self-assessment
Three quick questions. We weight your answers across geography, exposure, and case contact, then point you at the right next step. Not a diagnosis.
Common questions
The questions readers ask most. For deeper coverage, jump to the pillar, the symptoms page, or the triage decision tree.
What is hantavirus?
Hantavirus is a group of RNA viruses carried by rodents that can cause two human syndromes: hantavirus pulmonary syndrome (HPS) in the Americas and hemorrhagic fever with renal syndrome (HFRS) in Eurasia. Most infections occur via inhalation of aerosolized rodent excreta.
Is hantavirus contagious between people?
Most hantavirus strains are not transmitted person-to-person. The Andes virus, found in South America, is the only strain with documented human-to-human transmission, and only during close prolonged contact.
What are the early symptoms of hantavirus?
Early symptoms appear 1–8 weeks after exposure and include fever, muscle aches, fatigue, headache, nausea, and abdominal pain. Respiratory symptoms (cough, shortness of breath) develop later in HPS; kidney symptoms develop later in HFRS.
How fatal is hantavirus?
Case fatality varies by strain: up to 35–40% for Andes and Sin Nombre virus (HPS), about 5–12% for Hantaan and Dobrava (severe HFRS), and below 1% for Puumala (mild HFRS).
Is there a vaccine for hantavirus?
There is no vaccine licensed in the United States, Europe, or most of the Americas. China and South Korea use bivalent inactivated vaccines against Hantaan and Seoul viruses with high coverage in endemic provinces.
What is the MV Hondius outbreak?
The MV Hondius is an expedition cruise that departed Ushuaia, Argentina on 1 April 2026 with 147 people aboard. By early May 2026 the ship reported 7 cases and 3 deaths from confirmed Andes hantavirus, with 5 of 7 samples PCR-positive at Geneva University.
