An urgent virus alert has been issued for Sydney’s CBD after a worker tested positive to coronavirus.
The man aged in his 40s was an office worker in the Hunter and Bligh street area.
NSW chief health officer Dr Kerry Chant said the case was under investigation.
“Anyone who has been in the northeastern part of the city, including the Australia Square, MLC Centre and Chifley Square, should be alert for symptoms and isolate immediately and get tested should even the mildest symptoms develop,” she said.
“We’re asking anyone who has been in that area, please have a very low threshold for testing and please come forward immediately.”
NSW Premier Gladys Berejiklian said there was concern about people who may have been infectious and went to work in the CBD.
She said they could have then passed the virus on to other people in the CBD and those people could have passed it on in their communities.
“They are all eventually linked to the Avalon cluster but it does mean that there is potential transmission that we are not on top of and that is a concern,” the Premier said.
NSW Health has also issued an alert for the MLC Building food court at 19 Martin Place, Sydney.
Anyone who was at the food court from 1pm to 2pm on Tuesday December 15 has been considered a casual contact.
Those people have been urged to get tested and immediately self-isolate until a negative result is received.
Dr Chant said she was highlighting the CBD as an “additional risk” the community faced.
She said it was an area where they had seen infectious people and health authorities were aim to “mop up any unrecognised transmission” that was occurring.
Another new case reported on Thursday attended the Paragon Hotel sports bar at 1 Loftus Street near Circular Quay.
Anyone who attended the sports bar for more than one hour between 12.45pm and 3.30pm on Wednesday December 16 has been considered a close contact.
Those people should get tested immediately and isolate for 14 days even if they receive a negative result.
Anyone who was at the sports bar for less than an hour has been advised to get tested immediately and self-isolate until they receive a negative result.
It comes as the Premier revealed the New Year’s fireworks display in the Sydney CBD at midnight would “definitely” be going ahead.
“It will be happening no matter what,” Ms Berejiklian said.
“I’ll certainly be watching it at home. We encourage everybody else to do that as well.
“We have at this stage provided some access for frontline workers and others, but again, everything is reassessed based on the most recent cluster of cases.”
Ms Berejiklian announced nine new cases of community transmission in NSW on Thursday, with two still under investigation.
The remaining seven were linked to the northern beaches cluster, taking the total number of infections in the outbreak to 104.
