More than 1500 school pupils tested positive for Covid-19 in just one month.
And more than 70 schools had at least one pupil who had tested positive for the virus in the same period.
Public Health Scotland confirmed to the Courier that a total of 77 primary and secondary schools recorded cases between September 1 and the beginning of October.
A Freedom of Information request also revealed a total of 1,523 pupils tested positive.
It said 77 schools recorded at least one enrolled pupil testing positive for Covid-19, although the figures do not specify where the infection was acquired, or whether pupils were present in school at any point during their illness.
Of these, 17 schools had more than 10 pupils test positive within at least one school week from September 1 to October 7.
These were: Armadale Academy, Bathgate Academy, Broxburn Academy, Deans Community High School, Harrysmuir Primary, Inveralmond Community High School, James Young High School, Linlithgow Academy, Linlithgow Primary, Simpson Primary, Southdale Primary, St Kentigern’s Academy, St Margaret’s Academy, St Nicholas RC Primary, Uphall Primary, West Calder High and Whitburn Academy.
The findings come after the most recent stats show that West Lothian has seen a drop in covid cases and now sits third in Scotland’s league table compared to second last week.
This week’s seven-day positivity cases have fallen from 843 to 826.
First Minister Nicola Sturgeon gave an update to MSPs for the first time following the October recess on Tuesday.
She confirmed there will be no change to Scotland’s remaining coronavirus restrictions for now, but warned that the NHS remains under huge pressure.
The First Minister told MSPs that Scotland currently has the lowest Covid infection rate of the four UK nations, with case numbers well below the surge seen in late August and early September.
But the SNP leader also said that there had been a “slight increase” in cases in recent days.
Ms Sturgeon said there could be no room for complacency as around 600 people are being admitted to hospital with Covid every week in Scotland.
She said: “The pressures on the NHS are a reminder that Covid continues to be a threat – to our individual health and wellbeing, and to the capacity of our health and care services.
“This is why continued high compliance with existing mitigations and protections is so vitally important.”
