The configuration of latent varicella-zoster virus (VZV) DNA was analy
zed by PCR. Template DNA for both internal and terminal VZV primers wa
s present in a 1:1 ratio in ganglionic DNA, compared with a 15:1 ratio
in DNA extracted from VZV virions, indicating that the VZV genomic te
rmini are adjacent in latently infected human ganglia.
