WHO/ECDC global public health risk assessment held at LOW; ECDC EU/EEA risk: very low.

ECDC's surveillance update (page last updated 11 Jun 2026) reclassifies one of the two previously reported probable cases as confirmed following a positive laboratory result — revising the breakdown to 13 cases: 12 confirmed · 1 probable · 3 deaths (cumulative total unchanged; no new death). Per Wikipedia's outbreak timeline, the reclassification corresponds to the patient hospitalised on Tristan da Cunha (Case 8, British national) testing PCR-positive for Andes virus on 10 June. The sole remaining probable case is the deceased index case (Case 1, Dutch male, 70 — no PCR sample was ever taken). No new geographic spread: still 9 countries with confirmed cases. No new confirmed cases since the 10 June Tristan da Cunha result and no new deaths since 2 May. WHO DON604 (28 May) remains the most recent WHO Disease Outbreak News item; the ECDC surveillance page is the latest official source for the revised confirmed/probable split. MV Hondius remains in service after its Rotterdam deep-clean — operator Oceanwide Expeditions resumed regular operations (departed Rotterdam ~6 June bound for Svalbard, regular sailings from ~13 June). With 9 days remaining until the 42-day Andes virus incubation window for Tenerife evacuees (disembarked 10 May) closes on 21 June, WHO/ECDC continue active monitoring; the outbreak has not yet been formally declared over. ECDC notes additional cases remain possible after former passengers and crew return home given the long incubation period. All current and former Hondius crew members continue to be reported as symptom-free. Per CDC, the U.S. 42-day monitoring period closed 6 June with no cases detected; risk to the American public remains extremely low. WHO/ECDC global public health risk assessment held at LOW; ECDC EU/EEA risk: very low.

Important: as of today neither WHO nor ECDC has issued a formal 'outbreak over' declaration; the dashboard will reflect such a statement only when an official source publishes it. Still 9 countries with confirmed cases (Netherlands, South Africa, Germany, Switzerland, United Kingdom, United States, France, Spain, Canada). MV Hondius remains in service following its Rotterdam deep-clean, operating regular Svalbard sailings. All current and former Hondius crew members continue to be reported as symptom-free. Risk to the American public remains extremely low; WHO/ECDC global public health risk assessment held at LOW; ECDC EU/EEA risk: very low.

Seven days after the 42-day Andes virus incubation window for the Tenerife evacuees (disembarked 10 May) closed on 21 June with no new cases. Eighteen days since the most recent confirmation (Case 8, Tristan da Cunha, PCR-positive 10 Jun); no new death since 2 May. Cumulative totals hold at 13 cases (12 confirmed · 1 probable) · 3 deaths (case fatality ratio ~23%) per the ECDC surveillance update (page last updated 17 Jun 2026) and WHO DON604 (28 May 2026), which remains the latest official Disease Outbreak News item. Per WHO's fourth Disease Outbreak News report, as of 17 June 2026 a total of 13 cases have been reported, including 12 confirmed and one probable; some identified contacts have completed their quarantine while others are expected to do so in the coming days, and ECDC continues to assess the likelihood of additional cases related to this event as very low. The sole remaining probable case is the deceased index case (Case 1, Dutch male, 70 — no PCR sample was ever taken).

Eight days after the 42-day Andes virus incubation window for the Tenerife evacuees (disembarked 10 May) closed on 21 June with no new cases. Nineteen days since the most recent confirmation (Case 8, Tristan da Cunha, PCR-positive 10 Jun); no new death since 2 May. Cumulative totals hold at 13 cases (12 confirmed · 1 probable) · 3 deaths (case fatality ratio ~23%) per the ECDC surveillance update (page last updated 17 Jun 2026) and WHO DON604 (28 May 2026), which remains the latest official Disease Outbreak News item. Per WHO's fourth Disease Outbreak News report, as of 17 June 2026 a total of 13 cases have been reported, including 12 confirmed and one probable; ECDC reports that identified contacts have progressively completed their quarantine periods and continues to assess the likelihood of additional cases related to this event as very low. The sole remaining probable case is the deceased index case (Case 1, Dutch male, 70 — no PCR sample was ever taken).
