Because there is no such thing as total lockdown. In Spain, as in Italy, people go to buy food.
As we all know, one infected person, who may be asymptomatic can have a domino effect.
Incubation can be up to 14 days, most people will have symptoms before then, but some won't.
So, a person with mild symptoms or no symptoms could be going to the supermarket every day for 14 days hypothetically.
birds- we were like you a week ago, with that "this is never going to end" feeling. But despite the fact that the death toll is rising (which is expected after the infection rate plateaus) the experts here and the government are definitely cautiously optimistic now when they do the conferences daily. There is less "how can we stop this" and more "we are managing to stop this and now we mustn't let our guard down now at this stage"
Hang on in there .
