What to do if you have a positive COVID-19 test result
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. There is different advice for children and young people aged 18 and under.
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.
You may wish to ask friends, family or neighbours to get food and other essentials for you.
At the end of this period, if you have a high temperature or feel unwell, try to follow this advice until you feel well enough to resume normal activities and you no longer have a high temperature if you had one.
Although many people will no longer be infectious to others after 5 days, some people may be infectious to other people for up to 10 days from the start of their infection. You should avoid meeting people at higher risk of becoming seriously unwell from COVID-19, especially those whose immune system means that they are at higher risk of serious illness from COVID-19, despite vaccination, for 10 days after the day you took your test.
If you leave your home
If you leave your home during the 5 days after your positive test result the following steps will reduce the chance of passing on COVID-19 to others:
wear a well-fitting face covering made with multiple layers or a surgical face mask
avoid crowded places such as public transport, large social gatherings, or anywhere that is enclosed or poorly ventilated take any exercise outdoors in places where you will not have close contact with other people cover your mouth and nose when you cough or sneeze; wash your hands frequently with soap and water for 20 seconds or use hand sanitiser after coughing, sneezing and blowing your nose and before you eat or handle food; avoid touching your face
