What to do if you have a positive COVID-19 test result (over 19 years of age)
Try to stay at home and avoid contact with other people
If you have a positive COVID-19 test result, it is very likely that you have COVID-19 even if you do not have any symptoms. You can pass on the infection to others, even if you have no symptoms.
Many people with COVID-19 will no longer be infectious to others after 5 days. If you have a positive COVID-19 test result, try to stay at home and avoid contact with other people for 5 days after the day you took your test.
During this period there are actions you can take to reduce the risk of passing COVID-19 on to others.
Try to work from home if you can. If you are unable to work from home, talk to your employer about options available to you.
If you have been asked to attend a medical or dental appointment in person, contact your healthcare provider and let them know about your positive test result.
Children and young people aged 18 years and under who have a positive test result
It is not recommended that children and young people are tested for COVID-19 unless directed to by a health professional.
If a child or young person has a positive COVID-19 test result they should try to stay at home and avoid contact with other people for 3 days after the day they took the test, if they can. After 3 days, if they feel well and do not have a high temperature, the risk of passing the infection on to others is much lower. This is because children and young people tend to be infectious to other people for less time than adults.
Children and young people who usually go to school, college or childcare and who live with someone who has a positive COVID-19 test result should continue to attend as normal.
