Sydney apartment block residents locked down after ‘several’ cases of COVID

At least 100 residents in an apartment block in Sydney’s west are in lockdown after multiple people tested positive to coronavirus.

Police have been guarding the block of 50 units in Blacktown since 10.30pm on Monday night.

Since then, health authorities dressed in full PPE have been seen walking in and out of the building.

Every resident has been tested for COVID.

NSW Health confirmed six cases have so far been detected across three associated households in the building.

“Western Sydney Local Health District have worked with the residents and building management to assess the situation and, in collaboration with other agencies, are implementing measures to address infection control and the health and welfare of residents,” a Western Sydney Local Health District spokesperson said in a statement.

“All residents of the building have been determined to be close contacts.

“The NSW Police Force and private security are ensuring the safety of the building.

“Food and other services, including daily welfare checks, will be provided to residents safely during their 14-day quarantine period.

“Tailored support services will be provided to all isolated residents as needed.”

One resident, who described the situation as being “very scary”, told 7NEWS they were informed of the positive cases on Monday.

“It’s not just one family or one apartment,” she said, adding the virus could have spread in the building’s elevator or garbage room.

All residents will now isolate inside their units until midnight August 9.

“The NSW Police Force are providing support to NSW Health, who are responding to several cases of COVID-19 in an apartment block in Blacktown,” NSW Police told 7NEWS.com.au.

“NSW Police were asked to be on site in case assistance was required.”

The cases in the apartment block come after New South Wales recorded another 145 cases of COVID on Monday.

Since the beginning of the outbreak on June 16, more than 2200 people have been infected with the Delta strain.

NSW has also recorded 10 deaths linked to the current outbreak.

Across the state, there are 156 cases being treated in hospital, with 44 people in intensive care.

Of those in ICU, 18 are being ventilated.
