2. Individuals with shingles may transmit the virus to someone and cause chickenpox

It is widely known that shingles is non-contagious and can occur only in individuals who have had chickenpox in the past, by the action of their own VZV virus. However, this does not mean that transmission of VZV is completely impossible or absolutely harmless. People with shingles can pass on the virus to others who have not suffered from chickenpox yet and trigger the onset of the latter condition. Thus, it is strongly advised that children and adults who have not had chickenpox be kept away from a shingles patient.
