Abstract
Mice infected with herpes simplex virus (HSV) were treated (separately) with the nucleoside analog acyclovir or bromovinyldeoxyuridine by incorporating the drugs in drinking water. This method of treatment was effective for both drugs and compared favorably with i.p. injection. Prompt treatment with either compound could prevent the establishment of latent peripheral nervous system infections but latent infections once established were intractable using prolonged courses of oral administration.
