Herpes zoster results from reactivation of latent varicella-zoster virus in the dorsal root ganglia and is frequently associated with severe pain. Most patients suffer acute pain during the rash phase, and in many, prodromal pain or discomfort also precedes the rash. The pain of herpes zoster gradually resolves with time, but may persist after the acute disease as post-herpetic neuralgia for weeks, months or even years. Post-herpetic neuralgia, the most common complication of herpes zoster, often results in significant morbidity and healthcare resource usage. Early treatment with oral antivirals has been shown to accelerate the resolution of postherpetic neuralgia, with therapeutic effects particularly evident in the over-50 age group, where pain generally persists for longer. Progressively increasing life expectancy of the population translates to increasing numbers of cases of herpes zoster. The socio-economic gains associated with active management, including use of oral antivirals where indicated, to speed resolution of pain and post-herpetic neuralgia, readily justify additional cost.

Shingles update: common questions in caring for a patient with shingles.

Varicella zoster virus (VZV) is a herpes virus that can cause two distinct clinical diseases, chickenpox and shingles. Primary infection of varicella, often called chickenpox, results in a generalized eruption of a vesicular exanthematous rash which is usually seen in children and is highly contagious. This virus (VZV) can then become latent and later reactivate causing herpes zoster, commonly known as shingles. Shingles is usually a localized phenomenon often seen in adults and is usually less contagious. The following is a discussion of infection control questions most commonly asked regarding the care of a patient with shingles.
