In statement at Holyrood today (19 January), Sturgeon confirmed that the country's 'stay at home' order would remain in place with schools shut until the middle of next month.
She also added that, despite advancements in the roll out of the Covid-19 vaccine, physical distancing, face coverings and travel restrictions are expected to be necessary for 'quite some time'.
The situation with regards to lockdown restrictions will next be reviewed on 2 February.
Scotland entered a full lockdown at the beginning of January, but most hospitality businesses in the country have been closed since Boxing Day (26 December) when Level 4 restrictions were imposed across all mainland regions.
However, island areas - including Orkney and Shetland - have remained subject to Level 3 restrictions, meaning restaurants, cafes, pubs and bars can open indoors and outdoors for the consumption of food and non-alcoholic drinks, subject to a 6pm curfew.
Under Scotland's current lockdown restrictions, hospitality venues are still able to operate for delivery and takeaway.
Last week, however, Sturgeon did tighten restrictions on takeaway and click and collect services, with venues no longer allowed to let customers inside to collect orders.
Drinking alcohol outdoors is also now banned in all Level 4 areas of Scotland, putting an end to takeaway pints; although the sale of takeaway alcohol by hospitality businesses is still allowed.
