REGIONAL DATA
This hantavirus map covers both the active cruise cluster and endemic background risk worldwide.
| Region | Status | Cases | Deaths / CFR | Note | Source |
|---|---|---|---|---|---|
| MV Hondius cluster (multi-country) | Active | 8 (5 confirmed) | 3 | Andes virus strain. 12+ countries monitoring disembarked passengers. Ship docking at Granadilla (Tenerife) May 10. CDC escorting ~17 Americans to Nebraska quarantine unit. | WHO, May 7, 2026 |
| Argentina | Watch | 101 (since June 2025) | ~35% CFR historically | Hantavirus endemic. 101 infections since June 2025 — roughly twice the caseload of the prior year. Leading hypothesis links the cruise index case to Argentina. | Argentina Health Ministry |
| United States | Historical | 890 cumulative | ~35% case fatality (CDC) | CDC reports cases across many states, mostly rodent-exposure-linked hantavirus pulmonary syndrome. No current outbreak. | CDC, Apr. 23, 2026 |
| Europe (N. & Central) | Endemic | Several thousand/year | <1–12% CFR (HFRS) | Puumala and Dobrava viruses cause hemorrhagic fever with renal syndrome (HFRS). Finland, Sweden, Germany among highest burden countries. | WHO fact sheet |
| China & East Asia | Endemic | ~10,000–100,000/year globally | <1–15% CFR (HFRS) | China and Republic of Korea account for the majority of global HFRS burden. Hantaan and Seoul viruses are predominant strains. | WHO / PMC review |
| South Africa | Watch | 3 confirmed (cruise-linked) | 1 | No endemic presence. First known hantavirus cases on the African continent — all linked to MV Hondius passengers. NICD confirmed Andes virus by PCR. | SA NICD / SAnews |
| Americas (broader) | Watch | Varies by country | Up to 50% CFR (HPS) | Most hantavirus infections in the Americas present as hantavirus pulmonary syndrome. Bolivia, Chile, Paraguay, Uruguay also report endemic cases. | WHO fact sheet |
Confirmed 2026 cases are in the Netherlands (Amsterdam, Nijmegen), Switzerland (Zurich), and South Africa (Johannesburg). Three deaths occurred — two at sea in the South Atlantic and one in Johannesburg. All are linked to the MV Hondius cruise cluster.
The dashed line traces the MV Hondius vessel route from Ushuaia, Argentina through South Georgia, Tristan da Cunha, Saint Helena, Ascension Island, and Cape Verde, heading to the Canary Islands.
Twelve countries are actively monitoring disembarked passengers: Canada, Denmark, Germany, Netherlands, New Zealand, Saint Kitts and Nevis, Singapore, Sweden, Switzerland, Turkey, United Kingdom, and United States.
Hantavirus is endemic in the Americas (HPS), Northern and Central Europe (HFRS via Puumala virus), and East Asia — particularly China and South Korea (HFRS via Hantaan/Seoul virus). WHO estimates 10,000–100,000 global infections annually.
The leading hypothesis is that the index case contracted Andes virus during a birdwatching trip in Patagonia, Argentina in November 2025 — before boarding the MV Hondius. Argentina reported 101 hantavirus infections in 2025–26, roughly double the prior year.
