NSW outbreak stabilising as workers return

Case numbers and hospitalisations are plateauing and more health staff are back on the job, but tracking the spread of the virus in the community is still a challenge.

Healthcare settings still have a "Red" status, the highest of the three in the state's COVID-19 risk monitoring dashboard, updated weekly.

But "available metrics continue to point towards a stabilisation of the outbreak".

There remains "some uncertainty around levels of case ascertainment".

As of Monday, 3034 health staff were in isolation after potential exposure to the virus, down from 4523 the previous week.

Fewer people were admitted to hospitals with the virus but those who eventually found themselves in intensive care units were staying there longer, with those patients spending an average of over a week in ICU.

There were close to 33,000 fewer positive cases recorded in the week up to Monday compared to the previous week.

Case numbers have subsided from peaks in mid-January, but it's anticipated the return of children to classrooms could cause case numbers to rise again, as the government warned in the lead-up to the school return this week.

Parents have been urged to get their children vaccinated and boosters for themselves if they have not done so already.

Some 41.6 per cent of primary school aged children have now receieved at least one dose of the vaccine while 42.8 per cent of the state has received a booster (or top-up for immunocompromised people).

The opposition has taken aim at what it says is a lagging booster rate, calling for it to be mandated that essential workers receive a third dose to be considered fully vaccinated and that they get a half day of leave to do it in.

NSW has received the most boosters of any state or territory but more of the population is eligible due to being vaccinated earlier when the Delta outbreak locked down the state last year.

People who have recently caught COVID-19 - a sizeable group of more than a million in NSW - are also advised to wait four to six weeks after their infection to get a booster.
