NSW Health can confirm the viral genome sequence from the recent COVID-19 case who works at a Sydney quarantine hotel complex does not match the virus strains seen in recent clusters in Australia.
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.
NSW is working with Commonwealth agencies to identify potential COVID-19 cases among aircrew who stayed at the hotel, who may have since departed Australia.
Testing of close contacts of the case, and other staff at the hotel complex, is continuing. No further cases have been identified so far.
The case travelled on a number of train and light rail services between 27 and 30 November. People who travelled on the same services should get tested and self-isolate until they receive their results.
However, commuters who were in the same carriage as the case are considered
close contacts. These commuters are required to self-isolate for the full 14 days, even if they initially receive a negative result.
All affected services and carriage numbers can be found on
COVID-19 case locations and alerts in NSW.
There are more than 300 COVID-19 testing locations across NSW. To find your nearest clinic visit
