Every claim on this tracker is sourced. If we can't find a source, we retract the claim.
This is an independent tracker, not affiliated with any government or health agency. It was built to provide a clear, well-sourced picture of the MV Hondius Andes virus outbreak as it unfolds — organized by where patients are, not where they're from.
Data is drawn from official health agencies (WHO, CDC, ECDC, NICD, RIVM, UKHSA) and verified against reporting by CNN, ABC, BBC, Al Jazeera, NPR, NBC, CBS, PBS, Reuters, AP, Euronews, Daily Maverick, Time, STAT News, and Xinhua. This tracker actively monitored the outbreak from late March through June 2026. With the final exposure cohorts clearing their 42-day windows on 22 June 2026, active monitoring concludes on that date and the site becomes a fixed record. This does not constitute a declaration that the outbreak is epidemiologically over — WHO's formal end-of-outbreak declaration is expected later in 2026 — only that this tracker's active surveillance has ended.
