Why hantavirus isn’t the ‘next Covid’

For many people, news of a virus outbreak on a cruise ship immediately brings back memories of Covid-19 spreading when the Ruby Princess docked in Sydney in March 2020. Of the passengers and crew who disembarked, 575 had Covid. The virus then spread to the community.

So it’s understandable people are concerned that passengers from the MV Hondius need to be quarantined after potential exposure to Andes virus, a rodent-borne hantavirus.

However, the comparison with Covid only goes so far. Andes virus is serious and authorities are right to respond cautiously. But experts, including from the World Health Organization, note it doesn’t have the characteristics needed to become “the next Covid”.

As of May 11, European health authorities have reported nine cases linked to the cruise ship, including seven confirmed and two probable cases. Three deaths have been reported.

Five Australians and one New Zealander are being repatriated to Australia for quarantine and monitoring. The passengers will initially quarantine at the Centre for National Resilience near RAAF Base Pearce in Western Australia.
