There still seems to be some confusion over what to do should you test positive for COVID-19 so here is the latest NHS & Gov.uk information.
Those who are asked to, or choose to, take a COVID-19 test, and get a positive result should try to stay at home and avoid contact with other people for five days after the day of the test. If you leave your home during this time, following steps above will reduce the chance of passing on COVID-19 to others.
You should also advise anyone that needs to come into your home that you have a positive COVID-19 test result, so they can take precautions to protect themselves such as wearing a well-fitting face covering and keeping their distance if they can.
It is particularly important to avoid contact with anyone who is at higher risk of becoming severely unwell if they are infected with COVID-19, especially those whose immune system means they are at higher risk of serious illness from COVID-19, despite vaccination, for a 10-day period.
It is no longer a requirement for children and young people to test for COVID-19 unless directed to by a health professional. Children and young people tend to be infectious to other people for less time than adults, so if they have 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.
While you are infectious there is a high risk of passing your infection to others in your household, so try to limit your close contact with the people you live with, keep your distance and wear a face covering in communal areas, ventilate rooms and regularly clean frequently touched surfaces.
