Three new cases of COVID-19 were diagnosed in the 24 hours to 8pm last night and one previous case has been excluded, bringing the total number of cases in NSW to 4,009.

There were 15,239 tests reported in the 24-hour reporting period, compared with 16,843 in the previous 24 hours.

Of the three new cases to 8pm last night:

• Two are returned overseas travellers in hotel quarantine
• One is locally acquired and under investigation.

The locally acquired case worked at Concord Hospital while potentially infectious. The case cared for patients with COVID-19 and further investigation is underway to identify how the infection was acquired. Contact tracing is underway.

NSW Health advises that further assessments and testing of the case reported in Murrumbidgee Local Health District on Thursday has determined it was a false positive and therefore not a case. This case has now been excluded from the official count.

Locations linked to known cases, advice on testing and isolation, and areas identified for increased testing can be found at NSW Government - Latest new and updates.

While the number of locally acquired cases recorded in the past 24 hours is low, the virus is likely circulating among people in the community with mild symptoms. As such, the risk of outbreaks and a resurgence of cases remains.

It's vital that everyone who does have the virus is tested and diagnosed, in order to stop further spread to others.

NSW Health is again urging anyone feeling unwell – even with the mildest of symptoms such as a runny nose or scratchy throat – to come forward and get tested, so cases in the community are identified as quickly as possible.

This is even more important with the upcoming school holidays, when people will travel across the state.

NSW Health is treating 83 COVID-19 cases, including four in intensive care, two of whom are being ventilated. Eighty-six per cent of cases being treated by NSW Health are in non-acute, out-of-hospital care.

COVID-19 continues to circulate in the community and we must all be vigilant. To help stop the spread of COVID-19:

• If you are unwell, get tested and isolate right away – don't delay.
• Wash your hands regularly. Take hand sanitiser with you when you go out.
• Keep your distance. Leave 1.5 metres between yourself and others.
• Wear a mask on public transport, ride share, taxis, shopping, places of worship and other places where you can't physically distance.

A full list of COVID-19 testing clinics is available or people can visit their GP.
