People who are fully vaccinated or aged between 5 years and 18 years and 6 months, and identified as a close contact with someone who has tested positive for COVID-19, should take an LFD test every day for 7 days and continue going to school or college as normal, unless they have a positive test result or show symptoms.
Children under 5 are exempt from self-isolation and do not need to take part in daily testing if they are a close contact of somebody with COVID-19. Find out more about daily testing of contacts here: What you need to know about daily testing for COVID-19 contacts – The Education Hub (blog.gov.uk).
