Resumo: Determining the viral cause of a rash presents significant diagnostic challenges. We review contemporary literature on viral exanthems - suggest a structured approach to aid diagnosis. Strains responsible for, - the clinical presentation of, enteroviral infections have diverged from classic descriptions. The causative relationship between antibiotic administration - rash in Epstein-Barr virus infection has been recently questioned. Major measles virus outbreaks have recently occurred in Europe - the USA. The largest Ebola virus outbreak in West Africa has resulted in importation of the virus to other countries - secondary local transmission. Autochthonous transmission of Chikungunya virus has occurred in nonendemic areas, including Europe, the Caribbean - Americas. Zika virus has re-emerged in the Pacific with local transmission from imported cases. Climate change, global warming - spillover of zoonotic viruses are contributing to the emergence - spread of viral diseases. Important clues to the diagnosis of viral exanthems include their distribution - morphology, geographic location - potential exposure to vector-borne or blood-borne viruses. Diagnosis is commonly made via serology, nucleic acid tests or, rarely, viral culture. Skin biopsy is not usually required. In general, viral exanthems are self-limiting - treatment is supportive.
