There is no evidentiary basis for the extreme lock-down Spain is using.
While this disease is pretty contagious, you are pretty unlikely to get it walking around outside or going for a run. Especially if everyone is wearing a mask.
It's possible you could catch it by running through a cloud of an infected persons breath, but the risk is low enough that we shouldn't ban outside activities.
The vast, vast majority of infections occur from sustained contact (>15min) within a few feet of someone.
- zzzcpan 7y agoThis is an ancient understanding though, it ignores aerosol transmission. But you are still correct that outside is safe, there is absolutely no need to restrict it at all, it's confined poorly ventilated spaces that are a problem, like almost any building, cars, buses, planes, where the virus can concentrate in the air and close range contact isn't even needed, just breathing such air is bad enough. Wearing a mask is the only thing that helps to not get infected in such situations, but doesn't actually help much when infected people are wearing them, they still contaminate the air with aerosol.
