How long must I self-isolate for?
If you have symptoms of coronavirus, you’ll need to self-isolate for seven days, according to the advice put out by UK health bodies.
After seven days, if you do not have a high temperature, you do not need to self-isolate, notes the NHS.
Although, if you still have a high temperature, keep self-isolating until your temperature returns to normal, the health body advises.
