Parvovirus B19 (PVB19) is a ubiquitous airborne virus; it is well known to cause erythema infectiosum (fifth disease) in children. Neurologic complications after PVB19 exposure are thought to be transitory and infrequent in the adult population. Herein, we report an interesting case of a young woman who developed cognitive deficits, white matter changes and persisting viremia for over a year after exposure to PVB19.

Keywords: Cognitive deficits, encephalopathy, parvovirus B19, white matter changes.
