The latest published case rate is 70.9 per 100,000 - well above a key threshold for easing restrictions, though not as high as rates in Moray. Reasons behind the city's "red flag" increase are not yet known. However, Prof Linda Bauld said it was "extremely important" to identify the prevalence of the Indian variant.
