A man believed to be the patient zero of the Mercure Hotel cluster had recently returned to Perth from attending a wedding in India.
India is in the midst of a massive wave of coronavirus cases that has been clogging local hospitals and overwhelming local authorities. This week, the country set a new world record for daily infections after recording 314,000 new cases in a day.
There are about 34,000 Australians overseas registered as wanting to return, the largest cohort of whom, about 9000, are in India.
The man was in quarantine on a floor of the Mercure Hotel with 24 other overseas travellers when the virus spread across several rooms. A woman, her four-year-old child and a Victorian man who had recently returned from China were all infected.
The Victorian man, who has since returned to Melbourne, spent five days in Perth as a ‘tourist’ visiting several sites and transmitted the virus to a Kardinya receptionist who had hosted him at her home.
