Six Australians on board a cruise ship exposed to the deadly hantavirus have departed The Netherlands.NewsWire understands the Australian Government-supported flight carrying the six passengers - four citizens, a permanent resident and a New Zealander - departed the country after being evacuated from the MV Hondius.All have tested negative to hantavirus.Medical personnel are accompanying the group, who are due to touch down in Perth on Friday.It is understood passengers will be securely transported to the WA Centre for National Resilience in Bullsbrook with no community contact, where they will commence an initial three-week quarantine period.Health authorities earlier said they were “confident” the cruisegoers potentially were not infected.Health Minister Mark Butler said on Thursday the returnees had taken a “pre-flight test” and all “tested negative”.“I can also indicate they are all symptom-free,” he told reporters in Canberra.“So we’re pretty confident they’re getting onto the plane without the virus, certainly without symptoms.“But they will be subject to testing when they arrive in Australia, and they will be in full PPE during the duration of the flight so there is no risk of transmission.”Hantavirus is rarely transmitted between humans.Its symptoms start as flu-like, according to the World Health Organisation (WHO), typically including fever, muscle aches, fatigue, and headache.Symptoms often get worse quickly and can include coughing, shortness of breath and kidney failure.Three people exposed in the outbreak on the MV Hondius cruise ship caused three deaths.The WHO has confirmed 11 cases worldwide at the time of writing.
