I am not a physician, but I understand a person with a shingles rash can pass the virus to someone, usually a child, who has never had chickenpox, but the child will develop chickenpox, not shingles. A person with chickenpox cannot communicate shingles to someone else. Shingles can't be induced by exposure to another person with shingles or chickenpox. Those with active blisters can spread chickenpox to those who have never had chickenpox (and who have not been vaccinated against chickenpox).[Hopefully, children in daycare have been immunized against chickenpox.]
Someone with active blisters, can spread chickenpox to others who have never had that condition and who have not been vaccinated against it so it might not be a good idea since child might not have had chickenpox.
