A member of staff at a Dublin creche is thought to be the first in the sector to test positive for Covid-19.
Tusla and the HSE have both refused to comment, but the Minister for Children confirmed the positive test to the Dáil late last night.
He said his officials have been assured "all necessary actions have been taken".
Sinn Féin's spokesperson for children, Kathleen Funchion, says the positive test is a huge concern for the childcare sector.
