Authorities extend quarantine for six passengers from a cruise ship involved in a hantavirus outbreak in Western Australia. The people are held in quarantine in Bullsbrook, an outer suburb of Perth. Coverage reports that their quarantine period is prolonged until June 23, extending it by nearly another month. The extension follows the identification of additional confirmed cases linked to the same outbreak on the cruise ship. The measures apply specifically to the six passengers who were aboard the vessel that was affected by hantavirus, with the quarantine duration adjusted in response to the evolving public health situation. The reports do not describe individual medical outcomes, but they indicate that the continued risk of exposure is the basis for keeping the passengers under quarantine longer than the initial period. Overall, both sources state that the quarantine is extended for the same group of passengers and to the same end date, citing fresh developments in the outbreak as the reason for the change.
