Shingles Rash Symptoms
Patients with herpes zoster are infectious to those who lack immunity, but less so than patients with varicella. In contrast t herpes simplex I, the varicella-zoster virus (VZV) does not for the most part flare up more than once in adults with typically functioning immune systems. As people get older, their immune system naturally weakens to some germs, such as herpes zoster. The virus mainly lays dormant in nerve cells, but in certain people the virus reactivates years, or even decades, later and leads to herpes zoster.
are shingles contagious
Localized herpes zoster requires secretion precautions to guard against spreading of infection by direct contact with secretions from vesicles and from secretion-contaminated articles. In individuals with damaged immune systems, herpes zoster may be widespread (disseminated), causing serious illness. There is no agreement on how acute herpes zoster (shingles) should be managed in general practice. Although anyone who has had chickenpox can subsequently have herpes zoster (shingles), it is much more prevalent in individuals older than 50 years. The virus causing herpes zoster (shingles) is already present from an earlier infection with chickenpox.

is there a vaccine for shingles
Zostavax is a vaccine intended for the prevention of herpes zoster (shingles) and herpes zoster related postherpetic neuralgia (PHN). The vaccine challenge reactivates cellular immunity to VZV, preventing or weakening incidence of herpes zoster. The zoster vaccine markedly reduced mortality from herpes zoster and postherpetic neuralgia among older adults. In some cases a mild narcotic is needed to control the burning pain associated with herpes zoster.
