Scotland’s level system came into force in the Autumn, but the criteria for deciding on levels has since changed.
The government considers the World Health Organisation (WHO) thresholds when deciding on levels, which are that an area with over 150 cases per 100,000 people should be in level four, and anywhere with a case rate between 50 and 150 would be in level three.
An area with cases between 20 and 50 per 100,000 people would be in level two, and case rates below 20 would mean level one.
However, last week First Minister Nicola Sturgeon suggested that health chiefs will consider other criteria as well when deciding to ease restrictions, such as whether hospital admissions are rising in correlation with increasing case numbers.
These are the 12 areas in Scotland which exceeded 50 cases per 100,000 people between May 21 and May 27.
