A school pupil has been confirmed as having tuberculosis.
Health officials in Dumfries and Galloway said it is a single, isolated case in the area.
The infection is being dealt with in a "routine way", officials said.
Derek Cox, director of public health at NHS Dumfries and Galloway, said: ""NHS Dumfries and Galloway can confirm that a single isolated case of tuberculosis (TB) has been identified in a school child. We are dealing with this case in a routine way and in accordance with national guidelines.
"Although TB can sometimes be serious for those affected, it is usually easily treated with certain antibiotics, and most people make a full recovery."
Up to 500 cases of TB are diagnosed in Scotland each year. In Dumfries and Galloway, the number of new cases annually is "very small", usually accounting for less than 10 cases per year.
Mr Cox said: "In Dumfries and Galloway, TB is rare and it usually takes close, lengthy contact with an infectious person to catch the disease. So the risk of the disease spreading between people is very low.
"In line with national guidance, NHS Dumfries and Galloway is working very closely with the education department and the school concerned to identify those individuals most at risk and offer screening for TB."
TB is a bacterial infection spread by inhaling drops of saliva when an infected person coughs, speaks or sneezes. It mainly affects the lungs but can spread to other parts of the body including bones, skin and nervous system.
Typical symptoms are a persistent cough, coughing up blood, chest pain, tiredness, weight loss, fever and night sweats.
