In this section—

Any medical officer employed in the Department of Health, or other officer so employed and authorised by the Minister to exercise the powers conferred by this section on an officer so authorised, may at all reasonable times enter any public school or child care centre and examine the children attending the school or centre, and may notify the parent or guardian of any such child, or any other person whom he reasonably believes to be concerned with the welfare of the child, of any condition which in his opinion is affecting the health or normal development of the child or of any disease or defect from which in his opinion the child may be suffering.

The powers conferred by subsection (2) of this section may be exercised in respect of any private school, and in respect of the children attending there, if application in that behalf is made in writing to the Medical Officer of Health by the controlling authority thereof. Any such application may be revoked in like manner at any time.”
