You cannot get shingles from someone with chickenpox
You cannot get shingles from someone with shingles or chickenpox.
But you can get chickenpox from someone with shingles if you have not had chickenpox before.
When people get chickenpox, the virus remains in the body. It can be reactivated later and cause shingles if someone's immune system is lowered.
This can be because of stress, certain conditions, or treatments like chemotherapy.
