An elderly patient comes to see you complaining of a very painful rash. When he lifts his shirt,
you see that he has a rash of small blisters (vesicles) on one side of his back. You think he
likely has shingles, caused by varicella-zoster virus (VZV), a double-stranded DNA virus that
belongs to the Herpesviridae family. You explain this to your patient, who asks you to please
give him an antibiotic for his infection. You tell him an antibiotic will not help him, and give
him information on virus infections and their treatment.
Antibiotics are effective in treating viral infections provided that they are given early in the
course of illness.
