I think we need to sort out the terminology here (I assume we're talking about Covid).
If you're in quarantine, it's because you've tested positive for Covid, someone in your property has tested positive, or you've been contacted by track and trace to tell you you've been in close contact with someone who tested positive. It's also called self-isolation. If that's what you mean, and this all started five days after you arrived in Paris, then you're on the right track. I'd be inclined to make it clearer though:
Five days after I arrived in Paris, I was told I had to quarantine/self-isolate for ten days (after I tested positive/my wife tested positive/I had been in contact with someone who tested positive).
If you're talking about something everyone is having to do, then you need to talk about lockdown:
I arrived in Paris five days ago, and the city has just been put into lockdown for ten days. How frustrating!
