A characteristic feature of all herpesviruses is their ability to become latent, primarily in ganglia of the nervous system and lymphoid tissue. Virologic analysis of endoneurial fluid obtained during decompression surgery revealed HSV-1 DNA in 11 out of 14 patients with Bell's palsy.
Primary HSV-1 infection often results in painful skin or mucosal lesions, but can also be asymptomatic. HSV-1 from postmortem explants of human trigeminal,[7,8] nodose, vagal[9] and ciliary[10] ganglia. Neurons are the exclusive site of HSV-1 latency in human ganglia, and also in mouse and rabbit models. DNA is endless—that is, circular or concatameric[16]—and does not integrate into the host genome.

In ganglia latently infected with HSV-1, only one region of the viral genome is abundantly transcribed. Herpes simplex encephalitis (HSE) is a neurologically devastating illness associated with substantial morbidity and mortality in adults and older children. The correct recognition of HSE, and distinguishing it from other forms of encephalitis, brain abscess or mimicking disorders early in the course of evaluation facilitates treatment decisions when neurologic complications occur. The combination of clinical characteristics, magnetic resonance imaging of the head, and polymerase chain reaction (PCR) analysis of cerebrospinal fluid for herpes simplex type 1 DNA is a sensitive and specific way of diagnosing HSE for proper treatment. Whether prolonged therapy with oral antiviral treatment after standard intravenous acyclovir offers any advantage from the standpoint of neurologic morbidity or mortality is unproven.
PCR-negative typical cases and PCR-positive atypical cases of HSE can occur and require treatment with acyclovir. JavaScript is currently disabled, this site works much better if you enable JavaScript in your browser.

Increased CSF antibody to HSV-1, and a reduced serum:CSF antibody ratio, might help to diagnose HSV-1 encephalitis. Right, Coronal section showing mesial temporal lobe, insular necrosis in a case of herpes simplex virus (HSV) encephalitis. A precontrast CT scan showing a case of herpes encephalitis, notice the left medial temporal hemorrhagic zone surrounded by edema. This is an old but elegant study not likely to be repeated which examines whether viral isolates of the trigeminal ganglion and brain in the same patient are identical or not.
