title: Viral infections of the folds (intertriginous areas).
abstract: Viruses are considered intracellular obligates with a nucleic acid, either RNA or DNA. They have the ability to encode proteins involved in viral replication and production of the protective coat within the host cells but require host cell ribosomes and mitochondria for translation. The members of the families Herpesviridae, Poxviridae, Papovaviridae, and Picornaviridae are the most commonly known agents for the cutaneous viral diseases, but other virus families, such as Adenoviridae, Togaviridae, Parvoviridae, Paramyxoviridae, Flaviviridae, and Hepadnaviridae, can also infect the skin. Though the cutaneous manifestations of viral infections are closely related to the type and the transmission route of the virus, viral skin diseases may occur in almost any part of the body. In addition to friction caused by skin-to-skin touch, skin folds are warm and moist areas of the skin that have limited air circulation. These features provide a fertile breeding ground for many kinds of microorganisms, including bacteria and fungi. In contrast to specific bacterial and fungal agents that have an affinity for the skin folds, except for viral diseases of the anogenital area, which have well-known presentations, viral skin infections that have a special affinity to the skin folds are not known. Many viral exanthems may affect the skin folds during the course of the infection, but here we focus only on the ones that usually affect the fold areas and also on the less well-known conditions or recently described associations.
