Seventeen members of staff and two pupils have tested positive for coronavirus at a school in Dundee less than two weeks after Scottish schools returned.
Three “community contacts” linked to Kingspark School also tested positive for COVID-19 as of 6pm on Sunday, NHS Tayside said.
The school, which caters for children with additional support needs, has been closed since last Wednesday due to the outbreak and pupils have been told to self-isolate for 14 days from last Thursday.
Any parents, carers or siblings living with the children should also self-isolate if they cannot self-distance within the household.
Staff have been told to quarantine for a fortnight from the last day they were on site, while anybody who was in contact with those infected has also been told to self-isolate for 14 days.
Contact tracing identified a link with two other schools in Dundee, with one Primary Two child at St Peter and Paul’s School testing positive on Sunday and another case identified at the Happy Times out-of-school club at Downfield Primary School on Sunday.
The outbreak at Kingspark School, which only has 185 pupils, came after schools reopened in Scotland from 11 August.
Scotland’s first minister, Nicola Sturgeon, confirmed the outbreak on Monday and said: “Let me stress the importance of these rules on self-isolation.
“Self-isolation is a crucial way, perhaps the most important way, of keeping clusters like this under control.”
