If someone has had covid, then a house member gets it 2 weeks after. Does the original person have to re isolate

[BiscuitsNoMore]

? I can't see online.
Anyone have link to say about it.

I think so. The current rules are that if person A has symptoms, then person B isolates for 10 days. If person B gets symptoms after 14 days, then that's 4 days after they've mixed in public again, so it isn't a foregone conclusion that they've caught it from person A.

Then does person A have to isolate again?

Yes they do

ues. If the symptoms start during the original isolation then the first person dpesn't need to start again, once their isolation ends then they do.

Do you have a link for this.

no, I asked test and trace and thats what they told me.

"What to do if you develop symptoms of COVID-19 after your 10 days of self-isolation at home
If after 10 days of self-isolation you develop symptoms of COVID-19, stay at home and arrange to have a test. Follow Stay at Home: Guidance for households with possible or confirmed COVID-19.

If your result is positive, you must self-isolate for a further 10 days.

Will I need to self-isolate if I previously tested positive for COVID-19 but have now been notified that I am a contact of a person who has had a positive test result for COVID-19?
If you have previously tested positive for COVID-19, you will probably have developed some short-term immunity to the disease. However, it is not certain that will happen for everyone who has had COVID-19, nor do we know how long any immunity to the disease might last.

If you are notified that you are a contact of someone who has had a positive test result for COVID-19, you must immediately self-isolate and follow this guidance."
