Hantavirus Tracker

2026 MV Hondius Outbreak

This hantavirus tracker monitors the MV Hondius expedition cruise ship Andes virus outbreak (2026). The first death occurred aboard the ship on April 11; a second passenger died in Johannesburg on April 26, triggering WHO's international response. Exact exposure origin remains under investigation.

WHO initiated contact tracing covering passengers and crew across 14 countries shown on this map. Confirmed and probable case counts are synced from ECDC automatically every 20 minutes.

About This Hantavirus Tracker

The hantavirus tracker map covers both the 2026 MV Hondius active outbreak and compiled historical records (1993–present) across the Americas, Europe, and Asia — including HPS cases (Americas) and HFRS cases (Asia/Europe). Andes and Sin Nombre strains cause HCPS with a CFR of 35–50%.

Unlike other hantaviruses, the Andes strain is the only one with documented person-to-person transmission — which is why this hantavirus tracker follows repatriation flights and quarantine status across 14 countries.
