Queensland health authorities say they are "concerned" about the increasing spread of COVID-19 as the state recorded a more than 15 per cent rise in new case numbers in a day.
The state recorded 10,476 new known cases in the latest reporting period, compared to 8,881 yesterday. It is the highest daily jump in cases since January 29.
Seven more COVID-related deaths were recorded.
There are 252 people being treated in hospital for symptoms, including seven in intensive care.
Health Minister Yvette D'Ath said primary-school-aged children and people up to the age of 30 were making up the majority of new cases infected with the BA.2 Omicron sub-variant.
"[They] are the larger number who are getting this because they're the most mobile in the community and of course, they're passing this on to other people," she said.
She said the latest rise in cases was leading to more health workers having to isolate.
"We are concerned sadly with the increase in COVID cases," she said.
"We're not seeing an increase in ICU, which is great news and we're not seeing a significant increase in beds [being used for] COVID [patients].
"However, what I have seen in the last few days is an increase in health workers having to be isolated and quarantine again.
"We've got over 1,600 health workers again now actually in quarantine or isolation."
Officials closely monitoring Omicron sub-variant, rising cases
Ms D'Ath said she would not be implementing any further restrictions to curb the spread of the new sub-variant of until she received more advice from the Australian Health Protection Principal Committee (AHPPC), who are meeting today.
"It's too early again to know, but it is certainly having an impact on the number of people who are having to stay home," she said.
She said authorities were closely monitoring the situation and that they were not "surprised" about the spike in cases.
"We knew that the wave we had in December, January, February was not going to be the only one," she said.
She said the AHPPC will also be revisiting quarantine rules for people who are close contacts of positive cases.
"I have no doubt though we'll be considering that in light of what we're seeing with increased cases again," she said.
There have been no recommendations for people to receive a fourth shot of the COVID-19 vaccine yet, with only severely immunocompromised people currently eligible.
"For everyone else it is three shots and that's what we're asking people to get," Ms D'Ath said.
"We know the difference between that second vaccination and a booster. We've seen the difference in our hospitalisations and we've seen the difference in our aged care deaths as well."
