Premier Gladys Berejiklian confirmed a man from southwest Sydney, aged in his 20s, died from the virus at home after his condition “suddenly deteriorated” on Tuesday.
The man is the youngest COVID patient to die in the state since the beginning of the pandemic.
“He was a confirmed case of COVID and was isolating at home,” Chief Health Officer Dr Kerry Chant said.
“He was being cared for by South Western Sydney Local Health District during his isolation period and he’d reached day 13.
“He was being followed up daily by nursing staff and suddenly deteriorated.
“That death is being referred to the coroner.”
The man was living with one other person, who was also infected with COVID.
A woman aged in her 80s, from Sydney’s inner west, also died at Royal Prince Alfred Hospital.
Neither the young man nor the elderly woman were vaccinated.
There are 286 COVID patients being treated in hospital, an increase of 36 from Tuesday.
Of those, 53 are in intensive care, with 23 requiring ventilation.
The total number of cases in the outbreak is now 4063, with 17 deaths recorded.
Wednesday’s result comes after more than 105,000 people came forward for testing.
‘Concerning’ sewage detection
Chant added she was very concerned after fragments of the virus were detected in the sewerage networks in Newcastle, the Mid North Coast, the Central Coast and the central west.
Residents in the Belmont and Shortland areas of the Central Coast are being urged to be alert, as are Newcastle residents in Burwood Beach.
Detections were also made in Coffs Harbour and Bonny Hills and Mudgee.
“We want to see high rates of testing there, again to make sure there isn’t any unrecognised transmission in those communities,” she said.
The premier also indicated she believes the outbreak will continue to worsen.
“I actually think (case numbers) will get worse if you look at the number of people infectious in the community, it indicates that perhaps we haven’t reached our peak,” Berejiklian said.
