One person with the illness has died, but intensive care numbers did not see a comparable spike, lifting from 20 to 24 patients.
Premier Dominic Perrottet and Chief Health Officer Dr Kerry Chant will provide a COVID-19 update at 12pm (AEDT) today.
The new jump in NSW came as the head of the New South Wales branch of the Australian Medical Association sounded a note of concern over the end of the state’s mask mandate.
From today, masks are only required on public transport, in airports and on planes, and for front-of-house hospitality staff who are unvaccinated.
People are still “strongly encouraged” to wear masks when they cannot socially distance.
But NSW AMA president Dr Danielle McMullen said the rising case numbers were a worrying sign.
“We’ve been worried in the weeks leading up to this anyway, and encouraging the government to reconsider the mask mandate in particular,” Dr McMullen told Today.
“We know that indoor masks are a really simple, cheap way of reducing the spread of COVID-19.”
She said people were likely to be nervous about getting infected ahead of Christmas, particularly with parties and gatherings on this week.
“I think the best thing we can all do, to be able to have as much of a normal life as possible, is to keep those masks on indoors, get tested if you even have the slightest sniffle, go and get a proper PCR test,” Dr McMullen said.
“And if you’re going to a big Christmas gathering or you’re going to go visit nan or visit other elderly relatives, maybe think about doing one of the home tests before you go out, even if you are feeling fine, because we are seeing some spread from people who just don’t know they’re carrying COVID.”
Despite recording 804 new COVID-19 cases yesterday, just 21 people were in intensive care – compared to more than 200 when NSW last topped 800 daily cases.
Dr McMullen said doctors were “cautiously confident” that Omicron appeared to be a milder variant.
“Our health systems are coping, but even if it’s only a mild illness, we still can’t afford to have the whole community infected all at once,” she said.
Newcastle outbreak came from Sydney
A COVID-19 outbreak that has spread to hundreds of cases in Newcastle in the Hunter Valley has been linked to an alleged Sydney breacher, Health Minister Brad Hazzard has said.
“I believe that person was asked to self-isolate for seven days and that person apparently on the face of it may not have done that and went to a nightclub in Newcastle,” Mr Hazzard said.
Mr Hazzard also confirmed there has been a significant jump in people testing positive for the virus after attending the nightclub on December 8.
“What we do know is that out of the 650 to 680 people, there are now more than 200 patrons positive for COVID-19,” he said.
Testing is underway to see if these cases are the Omicron variant.
Anyone who went to The Argyle House nightclub from 9pm on Wednesday, December 8 to 3am on December 9 has been deemed a close contact and must immediately get tested, and isolate for seven days.
They must then minimise mixing with other people and avoid high-risk settings for the next seven days.
It’s understood a passenger with COVID-19 travelled on a flight to Brisbane, before catching a connecting one to Townsville.
