Contact tracing is underway at a Police Scotland building in Govan, which has been linked to positive Covid cases.
Test and Protect has advised close contacts of those positive to self isolate.
The Police Scotland buildings on Helen Street were previously hit with a number of positive cases in September 2020.
A spokesperson for NHS GCC told Glasgow Live: "Test and Protect is carrying out contact tracing of Covid-19 cases linked to a Police Scotland building in Helen Street, Glasgow.
"To respect and maintain patient confidentiality, no further details will be released, however we can confirm that those identified so far as cases or contacts have been advised to self-isolate.
"We would like to take this opportunity to remind everyone to adhere rigorously to the general advice and requirements that are set out on NHS Inform and Scottish Government websites, including immediately self-isolating and seeking a test upon developing any symptoms."
A Police Scotland spokesperson said: "Police Scotland is following Scottish Government and health guidance and where cases of coronavirus are identified, we work with the local health board and adhere to Test and Protect procedures.
"We have sufficient capacity and as a national service Police Scotland can flex resources should there be a requirement to do so."
