Covid-19 contact tracing is being carried out in Our Lady and St Patrick's High School in Dumbarton by NHS Test and Protect, health officials have announced.

NHS Greater Glasgow and Clyde has not provided information about the number of positive tests at the school, but says there is "no evidence of transmission" within the school itself at this time.

The health board said in a statement: "Close contacts are being advised to self-isolate and being given advice and support.

"Apart from those who are identified as close contacts, all other staff and pupils can continue to attend as normal.

"There is no risk to the wider community.

"We continue to ask the public to remain vigilant. The general measures to minimise the risk of Covid-19 remain the same – social distancing, regular hand washing, and being on the look-out for symptoms.

"There is no need for anyone to seek a test if they are not experiencing any symptoms but anyone with one or more of the symptoms should immediately self-isolate and order a test."

Tests can be ordered on the NHS Inform website.
