World-first: Macquarie University respiratory physician Professor Alvin Ing was on the MV Greg Mortimer Antarctic cruise ship when COVID-19 struck the passengers and crew in March. His subsequent research findings raise an alarm about how we may be underestimating the prevalence of the virus.

World-first research by Macquarie University physician Professor Alvin Ing has revealed the proportion of people with COVID-19 who are asymptomatic may be far higher than previously understood.

The study was carried out in real-time on the Australian-owned MV Greg Mortimer cruise ship, operated by Aurora Expeditions, which became stranded off South America in late March as border closures to combat the spread of COVID-19 swept the globe.

The research describes the first instance of complete COVID-19 testing of all passengers and crew on an isolated cruise ship during the pandemic. Its findings may apply in particular to similarly closed environments such as aged care homes, migrant camps and prisons, Ing says.
