Prevention and Treatment

Acyclovir and similar medications inhibit HSV DNA polymerase and halt the progress of herpes simplex, but they do not affect the latent virus and thus cannot rid the body of HSV infection. These medications are useful for treating severe cases and for preventing disabling recurrences. Since the ultraviolet portion of sunlight can trigger recurrent disease, sunscreens are sometimes a helpful preventive. ■ DNA polymerase, p. 171

Some of the main features of herpes simplex are shown in table 24.3.
