Shingles is contagious and can be spread from an affected person to babies, children, or adults who have not had chickenpox. But instead of developing shingles, these people develop chickenpox. Once they have had chickenpox, people cannot catch shingles (or contract the virus) from someone else.
Shingles is a disease thatâs closely related to chickenpox. The herpes zoster virus, also called varicella-zoster (VZ), causes both chickenpox and shingles. Once youâve had chickenpox, youâre infected with the herpes zoster virus.The virus stays in your body in an inactive state for the rest of your life.o even if a close family member has active shingles, the virus in your body wonât necessarily reactivate.
