"Apart from those who are identified as close contacts, all other staff and pupils can continue to attend as normal.
"The exception to this applies to East Renfrewshire, Glasgow City and West Dunbartonshire, where additional Covid-19 control measures are in place.
"In these local authority areas, any close contacts of someone who has tested positive for COVID-19 are being advised that they and all those in their household group, should self-isolate for 14 days."
