NSW Health is urgently seeking to identify the source of a coronavirus case that has emerged inside a quarantine hotel.
The return traveller, who was staying on the fourth floor of the Radisson Blu, is believed to have caught the virus from a couple who were staying on the same floor in an adjacent room.
All three travellers arrived in Sydney on the same flight from Doha, Qatar, on June 1.
According to NSW Health, it is unclear how and where transmission occurred.
“Early possibilities as to where transmission may have occurred from the couple to the secondary case include on the flight, on transport from the airport to the hotel, in the lobby of the hotel, or while in quarantine,” NSW Health said in a statement.
Genomic sequencing shows all three cases have the Alpha strain. So far, no other cases have been identified.
Traveller tested negative before returning positive test
The couple, who were asymptomatic, returned positive Covid tests on Day 2 of quarantine.
The secondary traveller returned a negative test on Day 2, before developing symptoms of Covid and testing positive on Day 4.
All three patients have since been transferred from the Radisson Blu to the Special Health Accommodation.
NSW Health is now contacting all returned travellers who stayed on the fourth floor of the Radisson Blu between June 1 and June 5 and asking them to get tested and isolate immediately pending further advice.
The same applies to all staff who worked on the fourth floor on the same dates.
The Radisson Blu has been providing quarantine services for returned travellers since April 2020.
