Hantavirus outbreak on cruise ship extends quarantine for passengers
Consensus Summary
Six passengers from a hantavirus-hit cruise ship (MV Hondius) are under extended quarantine in Bullsbrook, Western Australia, until June 23, 2026, after two new cases emerged overseas. The groupāfour Australians, one permanent resident, and one New Zealanderātested negative but remain asymptomatic. Health authorities extended the quarantine to cover the full 42-day incubation period for Andes hantavirus, a strain known for person-to-person transmission. The outbreak has caused 13 confirmed cases and three deaths, with the ship linked to rodent-borne exposure. Quarantine was initially set to end June 5 but was prolonged due to ongoing transmission risks, as advised by the World Health Organization and Australian health officials.
