title: [Varicella: how and when to start antiviral treatment].
abstract: The Meeting "An Update on Chickenpox" (Florence, 19-3-1993) has contributed to verify, in the light of the most recent acquisitions, the new guidelines for a correct rationale in the diagnosis and therapy of chickenpox. The present availability of an effective specific antiviral therapy for chickenpox (acyclovir) leads to a careful selection of patients to be treated. The high incidence of chickenpox morbidity keeps long unaltered and, beyond the usually benign onset of the primary infection in the child, the severity of this pathology in particular subjects and situations at risk is to be certainly underlined. Treatment is suggested for cases of chickenpox contracted inside the family. Generally, boys are at higher risk. Adolescents and adults, usually with a lower incidence, report a much higher severity of the acute onset and complications. Another category to be certainly treated is the one--in constant increase--of immunocompromised subjects. In any case, acyclovir treatment improves the symptomatologic evolution (pruritus and fever) and duration of clinical course. Among the progenitors of acyclovir, Valacyclovir seems to have the best prospects of success for the immediate future of antiviral therapy.
