It is no longer recommended that children and young people are routinely tested for COVID-19 (unless asked to by a health professional). If they do test positive however, they should not come into school and should try to stay at home for 3 days after the day they took the test. After 3 days, if they are well enough (and do not have an ongoing high temperature), they can return to school.
Children and young people with mild symptoms such as a runny nose, sore throat, or slight cough, who are otherwise well, can continue to attend school.
Children and young people who are unwell and have a high temperature should stay at home and avoid contact with other people, where they can. They can go back to school and resume normal activities when they no longer have a high temperature, and they are well enough to attend.
