Speaking to BBC Radio 4’s Today programme today, schools minister Vicky Ford said children who receive a positive lateral flow test must stay away from school.
The rule remains even if children receive a positive from this test and then get a negative PCR result.
People who come into contact with someone who receives a positive test must self-isolate for seven days.
Anyone who tests positive themselves must self-isolate for ten days, starting the day after their symptoms began.
