Hi Carla, the scope of that article was just any entry requirements.
I did find this for you on the France embassy page:
French authorities require people who test positive for COVID-19 to
self-isolate for 7 days (if fully vaccinated) or 10 days (if partially
vaccinated or unvaccinated), and alert those with whom you have been
in contact.

If I’m remembering correctly, you are trying to decide if you want to end your trip in France or Switzerland. Because Switzerland does not require isolation after a positive test, that might be a better option for you. I’m not advocating either one. I think it’s important to have the information, so each traveler knows what is expected in the event of a positive test.
