Herpes zoster is caused by reactivation of latent varicella-zoster virus that resides in a dorsal root ganglion. Herpes zoster can develop any time after a primary infection. Because varicella vaccine is a live attenuated virus, herpes zoster can develop in a vaccine recipient. The incidence of herpes zoster among vaccine recipients is about 14 cases per 100,000 person-years. In young children,...

statement of the problem: alveolar bone necrosis induced by herpes zoster infection is considered as a rare manifestation of osteomyelitis and few case reports are presented in the literature. purpose: the aim of this study was to evaluate mandibular osteomyelitis caused by herpes zoster in the immunocompromised patients with histopathologically documented osteomyelitis in the mandible and herp...

Varicella zoster virus (VZV) causes chickenpox and herpes zoster. Herpes zoster is a common infection in older adults and can lead to potentially debilitating postherpetic neuralgia. This article reviews the diagnosis and management of herpes zoster, including strategies to reduce disease frequency and severity with the herpes zoster vaccine.

The varicella zoster virus is the causative agent of herpes zoster and varicella. In herpes zoster, the virus dormant within dorsal root ganglia is reactivated, resulting in painful vesicular lesions overlying an erythematous base.

UNLABELLED Varicella-zoster virus (VZV) is responsible for both varicella (chickenpox) and herpes zoster (shingles). During varicella, the virus establishes latency within the sensory ganglia and can reactivate to cause herpes zoster, but the immune responses that occur in ganglia during herpes zoster have not previously been defined. We examined ganglia obtained from individuals who, at the ti...

Although herpes zoster is not a reportable condition in the United States, its incidence has been inferred from a variety of studies to range from 3.2 to 4.2 per 1,000 patient-years. This incidence translates into an estimated 1 million cases of herpes zoster annually. Overall, an estimated 32% of persons in the United States will have herpes zoster during their lifetimes. In a recent populatio...

acyclovir (9-[2-hydroxyethoxymethyl] guanine) is an acyclic nucleoside analogue of guanosine which is a potent and selective antiviral agent. acycloviris converted to the monophosphate by thymidine kinase the virus-specific form of this enzyme and is subsequently converted to the triphosphate by the host cell kinase. acyclovir triphosphate inhibits viral dna-polymerase terminating the chain and...

Varicella results from a primary infection with the varicella virus while herpes zoster is caused by a reactivation of a latent infection. Dissemination of herpes zoster is uncommon in immunocompetent individuals. Reports of disseminated herpes zoster in children are even less common than in adults. An unusual case of disseminated herpes zoster ophthalmicus in an 8-year old immunocompetent blac...

The Varicella Zoster virus persists in sensory nerve ganglion cells after chicken pox and gets reactivated to cause herpes zoster after variable periods of time as a result of waning of specific cellular immunity. Susceptible contacts of herpes zoster can develop chicken pox and very rarely herpes zoster. We report an interesting case of a father and his son who developed herpes zoster simultan...

Herpes Zoster is caused by the Varicella virus, characterized a unilateral vesicular rash, usually restricted to specific dermatome.
