Why do those surgical face masks prevent you from spreading an illness but not protect you from contracting one?

Question

Can’t I just…turn the masks inside out?

Kidding!

But really, I don’t get it.

Those masks do? I work in a hospital. We (as staff) wear them to protect ourselves. Basically the contaminated air droplets that the sick person breathes either (1) gets stuck in their mask or (2) cannot pass into our. Either way, they don’t pass it and we don’t catch it.
