R stands for reproduction and relates to the number of people someone with the virus can infect.
Scientists want to see it stay low, ideally under one to contain the spread and prevent further outbreaks.
The region’s 0.75 current R-rate means anyone with Covid-19 is likely to pass it on to less than one other person.
However, an NHS spokesman stressed there is still “a considerable degree of uncertainty” relating to the local number.
And he said: “There is a real fragility to this R number, where even a small change in social distancing and compliance with the national lockdown could lead to a significant increase in demand for services.”
The message in Dumfries and Galloway continues to be stay home to help stop the spread, observe social distancing and maintain good hand hygiene.
The spokesman added: “We believe the fantastic response in Dumfries and Galloway in complying with the lockdown measures has played a role in helping us to avoid an overwhelming surge in cases which might have been anticipated in the first wave of this outbreak and we thank everyone for their continuing support.”
