Scottish Government Covid-19 advisers have said the evidence does “not support” relaxing the two metre rule on social distancing.
The advice came as it emerged UK Health Secretary Matt Hancock said “some work” is being done reviewing the limit south of the border.
The two-metre restriction has been a key element of the strategy to suppress coronavirus across the UK.
However. businesses worry they will struggle to survive if it remains in place and schools are being radically restructured to cope with the requirement.
No international consensus exists on the correct distance, with Australia, Germany, Italy, the Netherlands and Greece backing a 1.5 metre rule.
France, Denmark, China and Singapore have a social distancing rule of one metre.
Hancock last night revealed the Scientific Advisory Group for Emergencies (sage) is looking at the science behind the social distancing measure.
Prime Minister Boris Johnson has also said: “Eventually I would like to do such things as reducing the two-metre rule.”
A minute of the June 4th meeting of the Scottish Government covid-19 advisory group reveals caution about any change north of the border.
It states: “The 2 metre rule. The evidence does not support changing this, but it should be noted that the effect of distance is on a continuum”.
Scottish Tourism Alliance chief executive Marc Crothall has previously warned about the continuation of the policy.
He said: "The reality, as I'm sure you know, is that the majority believe that it will not be economically viable to do so at two metres and as a result would have to close until such time as there was a change to the distancing measures.
"Many may not be able to hold out until then and the difference could mean many tens of thousands of jobs being saved or lost."
