Shingles is not a lifelong immunity after getting it. Herpes zoster, after active treatment, most can be cured, after the cure does not have lifelong immunity, most patients will not recur, but a small number of patients will recur when the body’s immunity is lowered, or even recurring episodes. Herpes zoster is a disease caused by varicella zoster virus infection, the initial infection with the virus will appear chickenpox or occult infection, after which the virus will be latent in the posterior root ganglion of the spinal cord, when the body’s immune system decreases, the virus will be activated again, thus causing the onset of the disease. Herpes zoster itself is self-limiting, and the principle of treatment should be based on antiviral, pain relief and anti-inflammatory, and prevention of complications. Early detection and treatment can effectively shorten the course of the disease, reduce the symptoms of neuralgia, and lower the risk of developing postherpetic neuralgia.
