Hantavirus Timeline

Complete timeline for the MV Hondius cruise-linked hantavirus cluster, including WHO notices, confirmed cases, deaths, repatriation, isolation, and contact tracing.

All recorded outbreak milestones

The homepage shows only the latest events. This page keeps the full archive so older vessel-route, case-confirmation, WHO, and repatriation details remain available without lengthening the tracker landing page.

CONFIRMED

US and French evacuees test positive during repatriation

A French passenger evacuated to Paris tests positive and is reported in serious condition. A US passenger flown to Nebraska tests positive for Andes virus but is asymptomatic; another American has mild symptoms. WHO-linked public-health advice continues to emphasize 42 days of active follow-up after last exposure.

RESPONSE

UK passengers enter isolation at Arrowe Park

A repatriation flight brings 20 British passengers plus two additional residents or travellers to Manchester. They enter isolation and medical assessment at Arrowe Park Hospital in Wirral after testing negative before departure from Tenerife.

DISEMBARKATION

MV Hondius arrives at Tenerife; disembarkation begins

The vessel reaches the Canary Islands in the early hours of Sunday. Passengers begin disembarking in small groups after screening, with Spanish passengers moved first and repatriation flights planned for the UK, US, Canada, Turkey, France, Ireland, the Netherlands, and Australia. Isolation or monitoring continues for 42 days after last exposure.

CDC RESPONSE

CDC escorts ~17 Americans to Nebraska quarantine unit

CDC dispatches staff to meet American passengers at Tenerife and escort them on a charter flight to the US. Nebraska Medicine's National Quarantine Unit — a federally funded facility — is standing by. All ~17 Americans on board are reported well with no symptoms.

VESSEL

Spain overrides Canary Islands opposition; ship to dock May 10

Spain's health agency approves the MV Hondius docking at Granadilla, Tenerife, citing international law and humanitarian principles — overriding the Canary Islands president who had declared the ship unwelcome. Vessel expected to arrive early May 10.

WHO UPDATE

WHO DON600: 6 confirmed, 2 probable cases

WHO updates the formal outbreak notice to eight cases: six laboratory-confirmed Andes virus infections and two probable cases, including three deaths.

TRACING

KLM flight attendant tests negative; monitoring continues

A KLM flight attendant hospitalised with suspected hantavirus — after close contact with the Dutch woman who died on the April 26 Johannesburg–Amsterdam flight — tests negative. WHO notes the long incubation period means further testing remains necessary.

WHO UPDATE

Three patients — including the ship's doctor — evacuated from the vessel in Cape Verde for specialist care. A British national in Johannesburg ICU is reported improving.
