[Febrile eruptions and herpesviruses].
There are 2 types of febrile skin eruptions due to herpesviruses: rashes (human herpesvirus 6 and 7. Epstein-Barr virus and cytomegalovirus), and vesicular eruptions (varicella and herpes zoster, primary and recurrent herpetic infections). Clinical diagnosis is often easy, based on the features of the eruption: characteristic sudden exanthem, clinical signs of infectious mononucleosis, or early vesicular trunk lesions characteristic of varicella or herpes. However, it must be stressed that exanthematic viroses can be highly variable. In some cases, and based on the background on which these eruptions occur, laboratory investigations will be necessary, according to the suspected virus.
