5/6/2026, 11:15:54 PM
Outbreak Overview: Disembarkation and Initial Response
On April 21, 23 passengers left the cruise ship MV Hondius, which is experiencing a hantavirus outbreak, at Saint Helena, ten days after the first onboard death. The remaining passengers stayed on the vessel under isolation. A Spanish passenger on board said the 23 disembarked individuals were not contacted by health authorities until three days before the WHO’s May 6 announcement.
Chronology of Key Events
- First death on MV Hondius (date unspecified, at least ten days before April 21).
- April 21: 23 passengers disembarked at Saint Helena.
- Early May (three days before May 6): WHO began contacting the disembarked passengers.
- May 6: WHO confirmed the outbreak is due to the Andes virus (ANDV) and that it spreads person-to-person.
Case Count and Clinical Outcomes
Eight cases have been identified, three laboratory-confirmed as Andes virus infections. Three deaths occurred; one patient remains in intensive care in Johannesburg and another is hospitalized in Switzerland. The other cases are under observation.
WHO Statements and Public Health Response
The World Health Organization (WHO) said the hantavirus outbreak on MV Hondius is caused by the Andes virus, the only hantavirus known to spread between humans. WHO officials noted that transmission requires close, prolonged contact with bodily fluids and that contact tracing is ongoing for all passengers, including those who left Saint Helena.
Passenger Criticism of Contact Delays
The Spanish passenger on board said the 23 disembarked individuals were not contacted by health authorities until three days before the WHO’s May 6 statement, describing the delay as a source of uncertainty. This reflects criticism of the timeliness of official outreach.
Passenger Accounts of Returnees
The Spanish passenger listed returnees: an Australian, a Taiwanese individual, Americans to various North American locations, an Englishman and a Dutch national. No Spanish nationals were among them. The passenger also reported that one disembarked traveler was hospitalized in Switzerland after testing positive for the virus.
Reporting Gaps and Uncertainties
The source notes WHO contact with Saint Helena passengers began only three days before the public announcement, but exact outreach dates are unspecified. The identities and health status of the 23 passengers who remained on the ship are also not detailed, leaving gaps in assessing potential secondary transmission.
