Scottish Conservative leader Douglas Ross asks the first minister why it took so long for Scotland to change its self-isolation rules when other parts of the UK had already done so.
Ms Sturgeon says she makes no apology for considering the matter "very carefully" and says the clinical advice she received was the risk of releasing people from isolation early would "outweigh the benefits".
While she says she thinks the change is proportionate at this stage, it is still not without risk.
"None of these things are straightforward", the FM says, adding that she will always be "accountable and open to scrutiny".
