Confirmed Hantavirus Cases: 10 Cases Across 8 Countries

Last updated: May 8, 2026 · 17:00 UTC

As of the May 7 World Health Organization Director-General briefing, 10 laboratory-confirmed Andes hantavirus cases have been reported across 8 countries in connection with the MV Hondius cluster. This page lists each confirmed case by jurisdiction. It is regenerated on every site build directly from our verified case database — if a jurisdiction is missing here, it is because no confirmed case has yet been reported by a Tier 1 health authority for that jurisdiction.

WHO has additionally noted three suspected cases pending confirmation. Those are not listed here. For the suspected and probable case picture, see the live map or the raw data feed.

Confirmed cases by jurisdiction

South Africa — Gauteng

Johannesburg · Case ID HV-002 · Last verified 2026-05-08

Two PCR-confirmed cases on South African territory. Case 2 (Dutch woman, wife of index case) died in Johannesburg emergency department April 26 — PCR-confirmed hantavirus May 4, the only death officially confirmed as hantavirus-caused. Case 3 (adult male) was medically evacuated from Ascension Island April 27 to a Johannesburg ICU, PCR-confirmed hantavirus May 2, alive as of May 7. Case 1 (Dutch man, husband / index case) died at sea April 11 — death attributed to Saint Helena (HV-006) where his body was removed April 24. Africa CDC contact tracing active for Johannesburg flight contacts. Condition improving as of May 7 per WHO and CBC. 60+ contacts identified from April 25 Saint Helena-Johannesburg flight on which confirmed Case 2 traveled. All successfully contacted individuals are being monitored per South Africa Health Department.

Netherlands — Noord-Holland

Amsterdam / Haarlem · Case ID HV-003 · Last verified 2026-05-22

RIVM contact tracing active. KLM flight attendant from Haarlem hospitalized at Amsterdam UMC tested negative for Andes hantavirus per WHO May 8 (case resolved). Three patients evacuated from MV Hondius arrived Netherlands May 7 — German, Dutch, and British nationals. Per WHO DON600 (8 May 2026) Cases 5 (ship's doctor) and 6 (ship's guide) are now tracked as their own records HV-024 and HV-025; the two confirmed-cases counts that previously sat on this Netherlands jurisdiction record have moved with them so the global confirmed total is not double-counted. QUARANTINE ORDER May 9 2026: Dutch Health Minister Hermans and Foreign Affairs Minister Berendsen jointly issued a formal 6-week home quarantine order for all Dutch MV Hondius passengers, confirmed in a letter to the Tweede Kamer. Per RIVM / ECDC protocol: asymptomatic returned passengers must self-quarantine for 6 weeks, may leave only for medical appointments and necessary exercise, must wear a medical face mask during any excursion, and will be monitored by local GGD health professionals at least weekly. Source: NL Times, government.nl (Tier 1). RIVM confirmed all three Dutch flight contacts (KLM / Schiphol) tested negative as of May 8. RUN-016 UPDATE May 12 2026: RIVM (Tier 1) confirmed that 12 healthcare workers at a Dutch hospital treating a hantavirus-positive evacuee from MV Hondius have been placed in preventative quarantine following procedural errors during blood collection and disposal of the patient's urine. RIVM considers the infection risk to be low. contactsMonitored increased from 53 to 65 (53 existing + 12 HCW). RIVM also reported that 3 people in the Netherlands with hantavirus-compatible symptoms have been tested: 2 results are negative, 1 test result is still pending analysis as of this run (01:09 UTC 12 May). The identity/category of the pending case is not yet specified; analyst flag: if the pending PCR returns positive, HV-003 confirmedCases would need updating or a new record created. Do not update confirmedCases until a Tier 1 source confirms a positive PCR result. RUN-018 CORRECTION May 13 2026: The third Netherlands PCR (previously recorded as 'still pending as of RUN-016 / 01:09 UTC 12 May') was confirmed NEGATIVE by RIVM on 08-05-2026 at 11:06 (Tier 1, rivm.nl/en/hantavirus/current-information). All three Netherlands symptomatic flight contacts (individuals who developed symptoms after contact on the SHN–JNB Airlink flight with Case 2) have now tested NEGATIVE. The 'pending PCR' watch item is closed; no new confirmed case in the Netherlands from this group. RIVM (Tier 1, 12-05-2026 15:45): All passengers arriving on the first MV Hondius repatriation flight (Sunday 10 May, Eindhoven Airport, 26 persons including 8 Dutch) tested NEGATIVE on arrival screening; samples cross-checked by both RIVM and Erasmus MC. Subsequent flights (Monday night / Tuesday morning) also screened on arrival with samples taken; results pending for those cohorts. All repatriated passengers subject to 42-day mandatory home self-isolation (quarantine period started 06 May). GGD monitoring daily by phone; weekly re-testing protocol in place. RUN-022 UPDATE 15 May 2026: Radboudumc (Tier 2) and NL Times report blood tests for the 12 Radboudumc healthcare workers in preventative quarantine show they 'were not contagious to others.' The 6-week precautionary quarantine continues per RIVM protocol but the contagion risk is resolved as low. This closes the 'HCW PCR results pending' watch item from RUN-016 through RUN-021. contactsMonitored holds at 65 (the 12 HCW remain in the tally per existing convention).

Rotterdam-Rijnmond GGD has erected 23 temporary quarantine cabins at the port to receive the 25 remaining international crew members. GGD will conduct PCR tests upon arrival. A decision on whether crew will serve the remainder of the mandatory 6-week quarantine at the port or elsewhere is still pending per Dutch health authorities (NL Times, 15 May, Tier 2). Docking confirmation NOT yet received — watch next cycle. RUN-025 UPDATE 17 May 2026 18:40 UTC: MV Hondius arrival timing revised — ship confirmed to dock MONDAY MORNING 18 May 2026, not evening 17 May as previously expected. 23 GGD quarantine cabins assembled at Rotterdam dockside. RIVM officials remain on board. Rotterdam-Rijnmond GGD will conduct PCR tests on arrival. 17 Filipino crew expected to remain in NL for the full 6-week quarantine. Source: TechTimes / Dimsum Daily citing Rotterdam-Rijnmond GGD / Oceanwide (Tier 2, 16–17 May). RUN-026 CONFIRMED 18 May 2026 14:18 UTC: MV Hondius has ARRIVED at the Port of Rotterdam, Netherlands, on Monday morning 18 May 2026. Disembarkation of the 25 remaining international crew members and 2 RIVM medical staff is underway. Rotterdam-Rijnmond GGD is conducting PCR tests on all arrivals per RIVM protocol. The 23 temporary quarantine cabins erected dockside by Rotterdam-Rijnmond GGD are now in use. Dutch health authorities and the Rotterdam GGD have oversight of quarantine management. 17 Filipino crew members are expected to remain in the Netherlands for the full 6-week quarantine. The ship will undergo disinfection while in port. Voyage of MV Hondius is now formally complete. contactsMonitored holds at 65 — the 25 crew aboard are already accounted for in the Rotterdam crew quarantine count per RUN-025.

RUN-026 SUPPLEMENT 18 May 2026 19:55 UTC: Granular docking detail per Port of Rotterdam official statement (Tier 2, via Pravda Netherlands) + Ports Europe (Tier 2) + Oceanwide Expeditions (Tier 2 via Al Jazeera AFP/AP): MV Hondius docked at Rotterdam Europoort, Calandsteiger 7 / Pier 7, approximately 10:30 local time (08:30 UTC) Monday 18 May 2026. Crew composition: 17 Filipino, 4 Ukrainian, 1 Russian, 1 Polish (+ remaining nationalities to Oceanwide total of 25). All 27 (25 crew + 2 RIVM medics) asymptomatic on arrival. Rotterdam-Rijnmond GGD administered PCR/virus tests to all 27 on arrival; results PENDING. Crew entered quarantine in 23 prefabricated white container units near Calandsteiger windmills. 17 Filipino crew will serve remainder of mandatory 6-week NL quarantine; 2 Dutch crew quarantining at home; remaining foreign nationals in dockside containers pending repatriation clearance. Disinfection contractor: EWS Group (engaged by Oceanwide in consultation with RIVM per Dutch Health Ministry letter to parliament). Dutch Health Ministry: 'Personal protective measures are being taken to ensure that cleaners do not need to quarantine after cleaning.' Public health officials will inspect the ship before it is allowed to sail again. WHO press statement late Sunday 17 May reiterates low-risk: 'while additional cases may still occur among passengers and crew members exposed before containment measures were implemented, the risk of onward transmission is expected to be reduced following disembarkation.' WHO press-conference figure cited '440 contacts in ≥30 countries' — NOT yet in a formal published DON; contactsMonitored on this record HELD per protocol pending formal Tier 1 DON. RUN-027 CREW PCR RESULTS 21 May 2026 19:09 UTC: GGD Rotterdam-Rijnmond (Tier 2, director Yvonne van Duijnhoven, cited NL Times / Irish Times, ~19 May 2026) confirmed all 27 persons aboard MV Hondius on Rotterdam arrival — 25 crew (17 Filipino, 4 Ukrainian, 1 Russian, 1 Polish) + 2 RIVM medical officers — tested NEGATIVE for Andes virus. This resolves the 'GGD arrival PCR results PENDING' watch item from RUN-026. 17 Filipino crew quarantining in mobile-home units, Rotterdam port; 2 Dutch RIVM officers returned home for mandatory 6-week quarantine. RUN-027 SUPPLEMENT 22 May 2026 01:29 UTC: RIVM (Tier 1, rivm.nl/en/hantavirus/current-information, 20 May 2026 16:50 CEST = 14:50 UTC) has directly corroborated — upgrade from Tier 2 GGD to Tier 1 RIVM. RIVM confirms all 27 disembarking persons tested NEGATIVE for Andes virus and that onboard tests taken prior to Rotterdam arrival also returned negative. RIVM SILENCE SIGNAL: 'As long as test results continue to be negative, RIVM will not issue further updates on test results. In the event of any positive test results, RIVM will publish these.' Future RIVM silence is therefore expected and should not be interpreted as a missed update. Dutch Minister of Health letter to parliament (Tier 1 source, reported via Pravda Netherlands / TASS Tier 2, published 21 May 2026 20:36 CET) independently corroborates crew PCR all negative and confirms '11 cases of infection' — consistent with current totals. ECDC INCONCLUSIVE CLOSURE: ECDC's 21 May 2026 update now shows 9 confirmed + 2 probable = 11 total, with the '1 inconclusive' count from 17 May no longer listed. ECDC (Tier 1) has implicitly closed the inconclusive-case flag from RUN-025/RUN-026 without a separate explanation; no new record created (analyst correctly held the line on 'do not add records without Tier 1 corroboration'). RUN-028 NEW CONFIRMED CASE 22 May 2026 14:45 UTC (16:45 CEST): RIVM (Tier 1, rivm.nl/en/hantavirus/current-information) reported 'Dutch national in quarantine has Andes virus.' One person in NL home quarantine has been diagnosed with Andes virus via weekly PCR protocol (RIVM + Erasmus Medical Centre dual laboratory confirmation). Person is a CREW MEMBER of MV Hondius who disembarked in Tenerife (Granadilla port, May 10–11) and was repatriated to the Netherlands; placed in home quarantine as a close contact of confirmed cases on board. Patient has since been admitted to hospital as a precaution and is in isolation. GGD is identifying any contacts the patient may have had during the quarantine period. WHO DG Tedros Adhanom Ghebreyesus publicly confirmed the same day (22 May, via Al Jazeera / NBC News / Manila Times / DutchNews.nl): 'Today, the Netherlands confirmed an additional case among a crew member who disembarked in Tenerife, was repatriated to the Netherlands and has been isolating since then.' RIVM silence signal triggered as expected (positive result = update published). This is the 10th PCR-confirmed case globally (12th total including 2 probables). confirmedCases for HV-003: 0→1; contactsMonitored: 65→64 (confirmed case exits monitoring pool). Source: RIVM (Tier 1) + WHO DG Tedros (Tier 1) + Al Jazeera/AFP/NBC/Manila Times/DutchNews (Tier 2–3). RUN-019 UPDATE May 13 2026: Filipino crew members quarantine in Netherlands. 38 Filipino crew members aboard MV Hondius are undergoing 42-day quarantine in the Netherlands. 24 of the 38 flew to Eindhoven Airport on a Netherlands government-arranged charter flight from Tenerife, landing approximately 1 AM local time May 12. All underwent medical tests on arrival; all tested NEGATIVE for Andes hantavirus. They are being held in designated quarantine facilities in the Netherlands during the 42-day period per Dutch/RIVM protocol, after which repatriation to the Philippines will be arranged. Remaining Filipino crew are still aboard MV Hondius en route Rotterdam. Their salaries and benefits continue during quarantine. The remaining crew aboard (25 total, which includes non-Filipino crew) are expected to disembark in Rotterdam on 18 May. Source: NL Times (12 May 2026), Philippine News Agency (12 May 2026), Philstar.com, Rappler — Tier 2–3 sources. The 38 Filipino crew contactsMonitored count is separate from the 65 RIVM-traced Dutch contacts; they are crew, not passengers, and are being quarantined by Dutch authorities. Analyst note: consider whether the 24 Filipino crew in NL quarantine should be reflected in contactsMonitored for HV-003 (would raise from 65 to 89). Pending human review decision.

France — France

Various · Case ID HV-011 · Last verified 2026-05-18

8 French nationals identified as close contacts on the April 25 Saint Helena-Johannesburg international flight, on which confirmed Case 2 (Dutch woman) also traveled. One individual previously displaying mild symptoms (cough); diagnostic tests underway and isolation measures in place. Not confirmed hantavirus infections. None were MV Hondius passengers. SHIP PASSENGER SUSPECTED CASE May 10 2026: One of five French nationals repatriated from Tenerife (MV Hondius ship passenger) developed fever and respiratory distress in-flight during evacuation. French PM Sébastien Lecornu (Tier 1) formally reclassified patient as 'suspect case.' All 5 French repatriates transferred by ambulance under police escort to Bichat-Claude-Bernard hospital, Paris (national reference centre for high-risk pathogens). All placed in strict isolation. PM Lecornu announced decree to implement isolation measures for close contacts and protect general population. PCR result pending from National Reference Centre. This is the first suspected ship-passenger case for France, distinct from the 8 April 25 flight contacts. FRANCE CONFIRMED CASE May 11 2026: French Health Minister Stéphanie Rist (Tier 1) confirmed one of the five French MV Hondius ship passengers evacuated to Bichat-Claude-Bernard hospital tested PCR positive for hantavirus — the woman who developed fever and respiratory distress in-flight during repatriation (classified as suspected case since May 10). Condition worsened overnight at Bichat before PCR result returned positive from National Reference Centre. The four other French ship passengers at Bichat tested negative; will be re-tested per protocol. French authorities now monitoring 22 contact cases nationally (including the 8 April 25 flight contacts and new contacts identified through ship passenger tracing). PM Lecornu quarantine decree for close contacts in force. This is France's first confirmed hantavirus case. confirmedCases: 0→1. suspectedCases: 1→0. RUN-016 UPDATE May 12 2026: contactsMonitored updated from 8 to 22 per French Ministry of Health (Rist statement, France Inter radio). 22 total contact cases identified in France: ship passengers + April 25 SHN-JNB flight contacts + additional contacts identified through tracing. French PM Lecornu confirmed the 8 April 25 flight contacts who had been self-monitoring are now in hospital isolation; none symptomatic as of May 11. French confirmed case (Bichat ICU) reported as 'deteriorating' by Health Minister Rist (France Inter) but 'stable' by PM Lecornu — reporting is inconsistent; monitor next cycle. The four other French ship passengers at Bichat still testing negative as of 11 May 18:31 UTC. French government decree published 11 May 2026 (Journal Officiel): mandatory 42-day hospital quarantine for all contacts, replacing previous voluntary self-monitoring guidance. RUN-018 UPDATE May 13 2026: French confirmed patient at Bichat-Claude-Bernard Hospital placed on ECMO (extracorporeal membrane oxygenation / artificial lung). Dr. Xavier Lescure, infectious disease specialist at Bichat (Tier 2, Bichat Hospital, NPR 13 May 2026): patient has a 'severe form' of the disease causing life-threatening lung and heart problems; she is on a device that pumps blood through an artificial lung to provide oxygen; Lescure called it 'the final stage of supportive care.' Condition is NOW 'CRITICALLY ILL' — clinical deterioration from 'stable' per PM Lecornu (May 11) and 'severe condition' per Health Minister Rist (Tier 1 press conference, May 12). Prior RUN-017 assessment of 'stable' is superseded. France Health Minister Rist (Tier 1 press conference 12 May): 'no elements suggesting the circulation of the virus on national territory'; all 22 identified French contacts directly linked to the cruise ship. Eight Saint Helena–Johannesburg (SHN–JNB Airlink, April 25) contacts all tested NEGATIVE per Minister Rist. Contact case from SHN–JNB flight (man, Concarneau, Finistère) self-reported and transferred to Rennes hospital; asymptomatic per Rist (May 12). Fourteen Johannesburg–Amsterdam KLM leg contacts: status of individual test results not yet publicly confirmed. French PM decree (Journal Officiel 11 May) requires self-quarantine within 3 days of notification; fines €1,500 (first offence) / €3,750 (repeat); driving licences may be suspended. RUN-021 UPDATE 14 May 2026: French Health Minister Stéphanie Rist (Tier 1, X / official statement, 14 May 2026, via France 24 / Manila Times / Al Arabiya / SCMP) confirmed 26 people in hospital isolation in France — breakdown: 22 close contacts of confirmed Case 2 (April 25 SHN–JNB flight, previously tracked) + 4 French ship passengers added to formal monitoring. All 26 tested NEGATIVE as of 14 May 2026; testing 3× per week continues. Confirmed French ECMO patient still in critical condition at Bichat; no clinical change reported this cycle. RUN-026 UPDATE 18 May 2026 19:55 UTC: France Pasteur Institute (Tier 2, published Saturday 17 May 2026, confirmed via Al Jazeera AFP/AP 18 May) has fully sequenced the Andes virus isolated from the French HV-011 patient at Bichat. Finding: the sequence matches viruses already known in South America; no evidence of new characteristics that would make the virus more transmissible or more dangerous. This closes the virological uncertainty watch item. The French confirmed case remains critically ill on ECMO at Bichat-Claude-Bernard Hospital — no clinical change reported in any source checked this cycle. The 26 contacts in hospital isolation (22 flight contacts + 4 ship passengers) all tested negative as of 14 May; tri-weekly testing continues.

Four Canadian citizens who were aboard MV Hondius disembarked in Tenerife on May 10 2026 and were repatriated to British Columbia via chartered Chrono Aviation Boeing 737. Route: Tenerife → Saguenay-Bagotville Airport, Quebec (stopover) → Victoria International Airport, BC. Aircraft landed Victoria on Sunday evening May 10. A PHAC officer was aboard the repatriation flight with masking and physical distancing protocols in place. The Canadian Armed Forces provided logistics support — limited to facilitating transfer on chartered flight. All four individuals have connections to British Columbia per BC Provincial Health Officer Dr. Bonnie Henry. None are considered confirmed cases or close contacts of symptomatic individuals. All four remain asymptomatic as of May 11 2026. Isolation protocol: minimum 21-day self-isolation in pre-arranged private lodgings in BC (not a hospital or facility), extendable to 42 days maximum based on last potential exposure (believed to be May 6 2026). Local public health teams monitoring daily. Secure plans in place for safe assessment and testing if any individual develops symptoms. PHAC risk assessment: overall risk to Canadian general population remains low.

The individual is Yukon-homed but monitored in BC; tracked under HV-013 (BC) per the testing/isolation jurisdiction, not a separate Yukon record. contactsMonitored retained at 4 (overlap with suspectedCases:1 is the 1 presumptive-positive individual already counted in the BC cohort). If NML confirmatory PCR is POSITIVE: upgrade to CONFIRMED_CASE, confirmedCases 0→1, displayColor #f59e0b→#dc2626, global confirmed 8→9. If NEGATIVE: revert suspectedCases→0, classification→CONTACT_MONITORING_ONLY, displayColor→#3b82f6. RUN-023 REFINEMENT 17 May 2026 12:49 UTC: Reclassification corrected — the BC presumptive positive is properly a PROBABLE_CASE not a SUSPECTED_CASE. Presumptive positive = provincial-lab (BC CDC) positive, PENDING confirmatory NML Winnipeg testing. Per established methodology this is the textbook definition of a probable case (cf. Saint Helena HV-006 probable, Tristan da Cunha HV-022 probable). suspectedCases 1→0; probableCases 0→1; classification SUSPECTED_CASE→PROBABLE_CASE; displayColor unchanged (amber covers both PROBABLE and SUSPECTED on the map). BC PHO briefing details (16 May): patient symptom onset ~14 May (fever, headache); BC CDC lab result received late evening 15 May; patient and partner transferred to hospital in Victoria for assessment; partner tested NEGATIVE; a third individual transferred 'out of abundance of caution'; a fourth continues isolating at home. Sources upgraded: PHAC Canada.ca media update; CBC, Globe and Mail, Times Colonist (Tier 3 corroboration). Global probable total: 2→3 (HV-006 + HV-022 + HV-013). Global confirmed total holds at 8. NML result expected within 24–48 hours from 16 May. RUN-024 CONFIRMATION 17 May 2026 16:27 UTC: PHAC NML (National Microbiology Laboratory, Winnipeg) issued news release Sunday 17 May 2026 (Tier 1) confirming that the Yukon resident isolating in Victoria, BC has tested CONFIRMED POSITIVE for Andes hantavirus. This resolves the RUN-023 probable flag. Patient hospitalized in Victoria with mild symptoms (fever, headache). Partner tested NEGATIVE per PHAC — no second case from this couple. Third individual transferred to hospital 'out of abundance of caution' — no positive result reported. Fourth traveller continues isolating at home. Classification upgraded: PROBABLE_CASE → CONFIRMED_CASE. confirmedCases: 0→1. probableCases: 1→0. contactsMonitored: 4→3 (confirmed case exits monitoring pool; 3 remaining = negative partner + caution-transfer + home-isolating). displayColor: #F59E0B→#dc2626.

Spain — Multiple

Mainland Spain · Case ID HV-015 · Last verified 2026-05-13

MV Hondius departed Cape Verde May 6, expected to anchor offshore near Granadilla port, Tenerife early Sunday May 10 (not directly docking). Passengers will be removed by small boats to isolated buses. WHO Director-General Tedros Adhanom Ghebreyesus will be present in Tenerife to coordinate evacuation. Spain Health Minister Mónica García, Interior Minister Fernando Grande-Marlaska also attending. 14 Spanish passengers to be flown to Torrejón air base and quarantined at Gómez Ulla military hospital, Madrid. Non-Spanish nationals to be repatriated from Tenerife. MAINLAND SPAIN FLIGHT CONTACTS (April 25 SHN–JNB flight): (1) 32-year-old woman in Alicante — formally classified as suspected case by Spain Secretary of State Javier Padilla; mild symptoms (cough); hospitalized in negative pressure isolation room, San Juan Hospital, Alicante. (2) 45-year-old woman in Catalonia — asymptomatic; newly identified May 9 after investigators found she changed seats during the flight, which complicated initial contact tracing; now formally a monitored close contact under Spain health protocols. (3) South African woman who spent several days in Barcelona before returning home — being tracked by Catalan health authorities; risk of transmission considered extremely remote. These three contacts are separate from the 14 Spanish ship passengers. Tenerife regional president Fernando Clavijo had resisted docking; national health minister confirmed ship will proceed. ALICANTE UPDATE May 9 2026: Spain Ministry of Health (Tier 1) confirmed via National Centre for Microbiology that the first PCR performed on the 32-year-old Alicante woman came back NEGATIVE for hantavirus. Per protocol, a second PCR is required 24 hours later. If second PCR is also negative, the patient will be reclassified as quarantined contact and transferred to Gómez Ulla Central Defence Hospital, Madrid. suspectedCases status maintained at 1 pending second PCR result (expected ~May 10 2026). ALICANTE RESOLVED May 10–11 2026: Spain Ministry of Health / National Centre for Microbiology confirmed the second PCR test for the 32-year-old Alicante woman was NEGATIVE (following first PCR also negative May 9). Both consecutive PCRs negative per protocol removes the suspected-case classification. She remains in isolation for continued monitoring per Spain MOH guidance and was transferred to Gómez Ulla Central Defence Hospital, Madrid. suspectedCases now 0. Catalonia contact (45yo woman) and South African Barcelona contact remain under monitoring; those two contacts are still active (contactsMonitored: 10 unchanged). RUN-017 UPDATE May 12 2026: Spain Health Minister Mónica García (Tier 1, X post Monday 12 May) confirmed that one of the 14 Spanish ship passengers isolated at Gómez Ulla Central Defence Hospital, Madrid, tested PRELIMINARY PCR POSITIVE for hantavirus upon arrival. The individual was initially asymptomatic and in good general health. By early Tuesday 12 May the patient began developing symptoms compatible with the disease (Tier 3 corroboration). The other 13 Spanish passengers tested provisionally negative; final results were expected within hours per García. WHO count updated to 9 confirmed + 2 probable = 11 total as of Tuesday 12 May. confirmedCases: 0→1. classification: TRAVEL_LINKED_LOCATION→CONFIRMED_CASE. NOTE FOR ANALYST: This is a PRELIMINARY positive. A second confirmatory PCR has not yet been publicly announced. The French case precedent (PCR positive = immediate confirmation per Health Minister statement) supports upgrading now; but the Alicante precedent (two PCRs required before resolution) would counsel holding at suspectedCases=1 until a second PCR confirms. Given that (a) WHO is counting 9 confirmed and (b) the patient is now symptomatic, upgrading to confirmed is recommended — but flag for review before pushing to production. If the human reviewer prefers to wait for a second confirmatory PCR, change the proposed diff to: suspectedCases: 0→1, confirmedCases stays 0, classification stays TRAVEL_LINKED_LOCATION. RUN-018 UPDATE May 13 2026: Spain Ministry of Health / National Centre for Microbiology (Tier 1) confirmed the SECOND PCR was POSITIVE for the Spanish passenger at Gómez Ulla Central Defence Hospital, Madrid. The case is now DEFINITIVELY CONFIRMED (no longer 'preliminary'). This resolves the RUN-017 analyst flag. Patient is symptomatic (mild respiratory symptoms, slight fever) but stable per ministry. The other 13 Spanish ship passengers at Gómez Ulla were reported provisionally negative; final confirmatory results expected. No change to confirmedCases (remains 1, set in RUN-017). WHO count of 9 confirmed remains valid.
