I predict that:
1. France will have an exponential explosion of cases.
2. France, after dragging its heels, will eventually undertake similar quarantine measures.
3. Whatever economic damage that early mitigation would have caused will be inflicted multi-fold, as the country reacts too late.
4. Those same doctors will be shrugging their shoulders, and crying: "How could anyone have foreseen this?"
5. People in the next country over will be busy arguing that the virus is causing irrational panic, and that all these measures are an overreaction.
