People who who have cold symptoms should not participate in conferences at all. It just that everyone almost to no exception will ignore that and still go since they have already invested so much time and money going to Brussels.
It the same problem with airports. Every person who is there with cold symptoms have decided that traveling that day is worth more than the risk of spreading illness to others.
The big innovation during the covid pandemic was not masks, it was the cultural shift of people staying inside when they had cold symptoms. Sadly we are now returning back where it is totally fine to again have cold symptoms in public. That is the choice that shouldn't be theirs to make.
