Core Event and Extension of Quarantine
On 28 May Australian Health Minister Mark Butler announced that the quarantine of six repatriated passengers from the Dutch-flagged cruise liner MV Hondius will be extended to a full 42-day period, ending on 23 June. The group – four Australian citizens, one permanent resident and one New Zealand citizen – arrived at a quarantine facility near Perth on 15 May after being evacuated from the vessel, which has been linked to a hantavirus outbreak.
Chronology
- 6 Apr: First passenger shows symptoms.
- 10 May: MV Hondius docks in Tenerife; passengers evacuated.
- 15 May: Six Australian-linked passengers enter quarantine in Western Australia.
- 26 May: WHO reports 12 confirmed cases, three deaths.
- 13 Jun: Ship scheduled to resume voyages after cleaning.
Data and Statistics
Confirmed infections have been reported as 11, 12 or 13; three deaths are confirmed; the ship carried about 150 passengers and crew from 23 countries; the incubation period of Andes hantavirus can be up to six weeks, prompting a 42-day monitoring window.
Key Figures and Organizations
Key actors include Health Minister Mark Butler, WHO Director-General Tedros Adhanom Ghebreyesus, Oceanwide Expeditions CEO Remi Bouysset, Rotterdam public-health director Yvonne van Duijnhoven, infectious-disease specialist Dr. Isaac Bogoch, and ship captain Jan Dobrogowski.
Official Statements and Responses
Butler said the quarantine will stay for the full 42-day incubation period. WHO Director-General Ghebreyesus called the situation stable and said monitoring will continue for all passengers and crew. The Rotterdam public-health service (GGD) ordered extra cleaning and will inspect the ship before it departs. Oceanwide Expeditions confirmed deep cleaning is under way and that voyages from 13 June will proceed as scheduled.
Criticism and Expert Concern
Infectious-disease specialist Dr. Isaac Bogoch cautioned that additional cases could appear during the 42-day window, noting the Andes virus can spread between people in rare instances despite WHO’s low-risk assessment.
Conflicting Reports and Gaps
Sources report 11, 12 or 13 confirmed infections and have not explained why GGD advised extra cleaning. Whether the virus was contracted before embarkation or onboard remains under investigation.
