Parvovirus: un solo virus per tante malattie

Parvovirus B19 causes a wide range of clinical manifestations, with a peak incidence between 5 and 15 years of age. The spectrum of clinical manifestations associated with Parvovirus infection varies depending on the host's age, haematological status and immune status. While common manifestations are generally easy to identify and allow an immediate diagnosis, uncommon ones often lead to confusion and diagnostic delays. The paper describes five cases of Parvovirus B19 infection with atypical presentation: dactylitis, cholestatic hepatitis, reactivation of autoimmune hepatitis, cerebellitis, and haemophagocytic lymphohistiocytosis.
