Portugal and Spain is interesting. Spain response is probably one of the worst in the world, with things getting so bad that the army had to clean out the dead from the living from abandoned nursing homes. I don't think you can compare the two really, since Spain's response seems so chaotic and mismanaged?

I got a feeling that picking the low hanging fruit in time (i.e. concerts, clubs, packed public transport) is enough to not get a big spike at all. Otherwise most European countries should explode since social distancing is no way taken as serious anymore.
