Peterhead Central School will remain shut this week following a minor outbreak of the disease.
NHS Grampian have confirmed this evening that two cases of Coronavirus have been detected at the primary school.
The health board is working closely with Aberdeenshire Council as investigations continue.
A statement said: “A second case of Covid-19, connected with a primary school in Peterhead, has been detected.
“Our investigations are continuing and we are working closely with Aberdeenshire Council.
“They have delayed the reopening of the school in the meantime.”
Councillor Stephen Calder said he was “shocked but not surprised” after a the school was forced to close earlier today.
He said: “We were worst hit in the first wave back in April as an area of multiple deprivation and growing poverty and inequality. I warned this could happen for weeks.
“This isn’t a criticism of the schools. We shouldn’t have opened up to full class sizes with no protection or physical distancing, my preference would have been to continue blended learning with partly smaller class sizes.”
Last night an Aberdeenshire Council spokesman told the Evening Express “A number of staff from Peterhead Central Primary School are currently self-isolating following the identification of a confirmed case of coronavirus within the school team.”
In a statement, the health board confirmed the case was being investigated. They said: “We are investigating a detected case of Covid-19, connected with a primary school in Peterhead.
“Our health protection and Test and Protect teams are working hard to establish who close contacts may be and advising them to isolate.
“We are also working very closely with our colleagues at Aberdeenshire Council.”
The council made the decision to shut the school last night.
MSP for Banffshire and Buchan Coast, Stewart Stevenson praised Aberdeenshire Council for their “swift action in managing what is understood to be a household outbreak.”
Mr Stevenson said: “Test and Protect procedures have been put in to swift action as a result. I am hopeful of the swift return of pupils to Peterhead Central Primary School when it is safe to do so.”
In response to the news of the schools closure, one social media user said: “We really have to learn to live with this virus or we are going in collapse.”
