Adults and children aged 12 and over still have to wear face coverings in all the same indoor settings as before, such as shops, hospitality venues and public transport.
People are also being asked to wear masks in outdoor crowded areas.
What are the rules on self-isolation?
People who test positive for Covid in Scotland will be allowed to exit self-isolation after seven days if they have no fever and record two negative lateral flow tests.
The first of these tests must be taken on the sixth day after testing positive and then at least 24 hours later.
The move, which came into force on 6 January, brings Scotland into line with England, Wales and Northern Ireland.
In addition, household contacts of people with the virus can take a lateral flow test every day for seven days rather than going into self-isolation.
This applies to everyone in the household under the age of 18 or anyone over that age who has had the first, second and booster Covid jabs.
If one of these tests is positive, self-isolation will then be required for that person.
Anyone identified as a close contact who is over 18 and four months old and not fully vaccinated will still be asked to self-isolate for 10 days and take a PCR test.
