NHS Dumfries and Galloway say they are aware of “a small number of cases”.
A spokesman said: “Parents in affected settings have been informed. The cases are not considered to represent a significant public health concern for the region.”
Scarlet fever is an infectious disease which mainly affects children of nursery or primary-school age. It is treated with antibiotics and will rarely cause serious illness.
Symptoms include sore throat, high temperature and headache, followed a day or two later by a pinkish rash.
Illness rarely lasts more than a week, but people with scarlet fever may infect others with whom they come into close contact, and so they should remain at home rather than going to work, school or nursery.
Anyone who believes they or their child may have scarlet fever should consult their GP, who will be able to diagnose scarlet fever and prescribe antibiotics if appropriate.
