A Brisbane childcare centre has been shut after a child tested positive to swine flu, with cases of the virus in Queensland rising to 53 last night.

Five new cases were recorded yesterday, including Queensland origin player Ben Hannant, who is in isolation on the Gold Coast.

A 10-year-old girl linked to Ferny Hills State School in Brisbane, which has been closed by the outbreak, has been listed as a probable case.

The others new cases include a 45-year-old Moreton Bay woman, a 24-year-old Cairns man and a 25-year-old Gold Coast man.

The Hamilton Road Early Education Centre at West Chermside will shut for a week.

Queensland Health is contacting parents after one child at the centre tested positive.

Children who had close contact with the child will be given anti-viral medication.

More than 2,000 passengers who disembarked the cruise ship Dawn Princess in Brisbane on the weekend were screened but none required testing.

Cairns schools

Meanwhile, six students in far north Queensland who contracted swine flu are expected to return to school today when two Cairns Catholic colleges reopen.

St Mary's and St Monica's colleges have been closed for a week.

Dr Bill Sultmann from Catholic Education in Cairns says he is delighted the schools can reopen on schedule.

"We're conscious that it was very disruptive, particularly at this time of the year, and certainly difficult for families to make adjustments," he said.

"But it was a decision I think taken on a variety of reasons - associated with the school, the community, general health, and advice, so we hope it's been for the good.

"Dr [Jeannette] Young, [Queensland Health's] chief medical officer, was taking a fairly conservative view, which we thought was prudent and I think it's proved effective.

"Within Cairns, there's been a restricted number of cases.

"We expect that not to explode - we hope it won't explode."

Cairns State High School will stay closed until Thursday after a second student contracted the virus.

Warwick

Warwick State High School in Queensland's south-east is expected to reopen today after a swine flu scare.

The school was closed last Thursday as a precaution after a student - whose sibling tested positive to swine flu - showed symptoms of having the illness.

Parents were told late on Wednesday night about the closure.

Queensland Health authorities also opened a clinic at the nearby Old Oaks nursing home treating 124 people for flu-like symptoms before closing on Sunday.

No students from Warwick State High School contracted the virus.

So far there are only two swine flu cases in southern Queensland - one in Warwick and the other in Toowoomba.
