SINGAPORE - A PCF Sparkletots centre in Choa Chu Kang has closed after two children from the same household tested positive for Covid-19.

All children and staff from the Playgroup to Kindergarten 2 classes who were recently in school with the affected children have been placed on leave of absence from Wednesday (July 14) to July 26, lead executive principal Janica Ng said in a letter to parents.

The centre, PCF Sparkletots @ Brickland at Block 801 Keat Hong Close, is closed from Wednesday to Thursday for deep cleaning and disinfection of the premises and equipment, and contact tracing is under way, she said.

The Ministry of Health (MOH) informed the centre on Wednesday evening that a child from Kindergarten 1 had tested positive. A second child from Playgroup was then confirmed with the virus on Thursday morning.

Both children were last in the centre on Monday and had cleared all temperature checks without any symptoms of being unwell.

The centre is unable to provide further information on the two children due to patient confidentiality and will be working with the authorities to ensure the safety of all staff and children.

MOH may contact parents with children enrolled in the centre, Ms Ng added.

Infant care services will resume first on Friday, while all other classes are expected to resume on July 27.

"We seek your understanding and cooperation to make alternative childcare arrangements during this period," said Ms Ng.

Ms Marini Khamis, senior director of the preschool management division at PCF later said in a media statement that it is monitoring the situation closely with MOH and the Early Childhood Development Agency and will contact parents to follow up on the well-being of their children.

"We also stand ready to adjust or step up our measures where required or upon ECDA's advice," she added.

Parents are advised to monitor the health of their children and to seek medical attention if they are unwell, she added.
