That helps, but at least for Spain and Italy, the hypothesis seems to be that the virus was already widely spread by the time lock-down started, so a lot of transmission still happened during lock-down until it got under control. I think it's the same for UK and France. but I'm less familiar.
Other EU countries like Germany, Austria or Poland fared much better than Spain, France, UK and Italy.
Maybe different cultures (e.g. how people relate, how compliant they are, how many people willingly ignore measures, etc.) also play a role.
