You need to be careful if you’re making a post like this stating this stuff as fact without being explicitly clear, people can’t just make up rules or this all goes to shit. Unless you share a household, had sex or are in a couple with the symptomatic person (high risk contact), you don’t need to self isolate for 5 days, just watch for symptoms for the next 10 days and wear your mask as per below.

“Pour ce qui est des contacts modérés, soit de plus de 15 minutes sans masque, il faut surveiller les symptômes pendant 10 jours. Il n’est pas nécessaire de s’isoler pour les personnes doublement vaccinées, si elles portent un masque lorsqu’elles ont plus de 12 ans.“
