No new cases of locally acquired coronavirus have been recorded in New South Wales in the 24 hours to 8pm on Friday.
Two new coronavirus cases were recorded from returned overseas travellers, who are within the state’s hotel quarantine system.
NSW Health has also linked the recent infection of a Sydney hotel worker to a US strain of the virus.
“The viral genome sequence from the recent COVID-19 who works at a Sydney quarantine hotel complex does not match the virus strains seen in recent clusters in Australia,” Dr Stephen Corbett said.
“The virus may be of United States origin. The source of infection may be international aircrew who were self-isolating in the hotel at the time, however investigations are continuing.”
No further positive cases are linked to the incident. Australian health authorities are seeking to contact potentially infectious aircrew staff.
The infected woman travelled on a number of train and light rail services between November 27 and 30, including trains between Minto and Lidcombe and Lidcombe and Central, and light rail between Central and Capitol Square and Central and Convention.
NSW Health has urged anyone in the Minto and Lidcombe areas to come forward for testing if they have flu-like symptoms.
The total number of cases recorded in NSW since the start of the pandemic is 4416 and 11,593 tests were reported in the past 24 hours.
Victoria has also recorded no new cases and no lives lost from COVID-19 in the past 24 hours.
