Shingles nerve damage. Artwork illustrating the effect of varicella-zoster virus particles (blue spheres) on nerves. An infection of the nerves by this virus is called shingles or herpes zoster. It results from a reactivation of this virus from an earlier chickenpox infection. An inset (lower centre) shows the double helix core of ribonucleic acid (RNA) that allows the virus to replicate. It travels along sensory nerves (green) to reach the skin and causes the outbreak of small blisters (red,upper right). The blisters last around two weeks and,if untreated,nerve damage causes severe pain in the affected area. Antiviral drugs,like acyclovir,can help if taken early on | |
