But how long do you self-isolate for?
If you – and you don’t live with anyone else – have symptoms of coronavirus, you’ll need to self-isolate for seven days.
If you or someone in your household has symptoms, you’ll need to self-isolate for 14 days from the day their symptoms started. This is because it can take 14 days for symptoms to appear.
If more than one person at home has symptoms, self-isolate for 14 days from the day the first person started having symptoms.
Piers also confirmed on the show he does not have coronavirus symptoms after he started coughing live on air.
Chatting to Dr Hilary, who sat away from Piers and Susanna, he said: “I just coughed there and I know some people at home will be thinking, oh there he goes he has got it.
“People on TV cough all the time, I hear people do it on air. But it will worry people. The moment you do everyone goes mad.
“I don’t have a persistent cough of symptoms of coronavirus.”
