Everyone living in the DG13 and DG14 postcode areas is being encouraged to come forward for testing – regardless as to whether or not they are currently experiencing symptoms.
It is the first time that mass testing has taken place in Dumfries and Galloway and NHS chief officer Julie White said: “We’re currently seeing a particular concentration of cases in the Langholm and Canonbie areas.
“We are encouraging all residents in these postcode areas to come forward to be tested over these four days – in the hope that we can we can identify live cases and help halt the spread.
“Testing of a population in general has not been undertaken before within Dumfries and Galloway, and this process and its outcomes will be closely monitored.”
A testing site has been set up at the Kilngreen car park, pictured, and will remain there until tomorrow, Tuesday.
Appointments must be made in advance through the www.nhs.uk/ask-for-a-coronavirus-test website.
