People who get coronavirus symptoms in the UK must now self-isolate in their home from at least 10 days, starting from today.
Chief Medical Officers have confirmed an immediate change to the rules - extending the time by three days from the previous minimum of 7 days.
The three Covid-19 symptoms to self-isolate for are a persistent cough, fever and change or loss of taste or smell. Any one of those three symptoms should trigger isolation.
However, people can be "released" from isolation early if a Covid-19 test comes back negative. It is understood the decision was taken after medical officers discovered a "low but tangible possibility" that some patients remain infectious more than a week after symptoms begin.
