Herpes zoster is clinically considered to be an acute infectious skin disease caused by the varicella-zoster virus. Children who are not immune to this virus may develop chickenpox if they are infected, and there are certain children who may be infected without any symptoms and are simply called simple carriers. Because this virus easily invades from the nerves, the virus can remain latent in the neurons of the posterior root ganglion of the spinal nerve for a long time after infection. When the affected child has low resistance or is tired, infected, has a cold, fever, or abdominal pain, the varicella-zoster virus can grow and multiply again and grow from the nerve fibers, which can be transferred to the skin, causing particularly intense inflammation of both the nerves and the skin in the affected patient. The rash usually occurs unilaterally and is distributed along the nerve segments, and the rash is found to be composed of clusters and masses, and is accompanied by particularly intense radiating pain. It has been found that the older the person is when shingles occurs, the more severe the painful symptoms of the nerve, especially when shingles occurs mainly at an older age and is more common in the cooler seasons of spring and fall.
