Herpes zoster is a viral infectious skin disease that is most prone to epidemic in the spring, primarily caused by the varicella-zoster virus. It generally lies dormant in the body causing a belt-like cluster of herpes zoster to appear along the dermatome, accompanied by neuralgia. The course of herpes zoster generally lasts three to four weeks, and it usually does not recur after recovery. The main principles of treatment are antiviral, analgesic, anti-inflammatory, to shorten the duration of the disease, and to prevent secondary infections.
