Laryngitis and neutropenia from parvovirus-B19.

Parvovirus-B19 has been reported a rare cause of acute laryngitis. Here, we described an 11-month-old girl who had prolonged acute laryngitis and neutropenia associated with parvovirus-B19 infection. Intravenous immunoglobulin therapy resulted in resolution of her symptoms, except neutropenia. We concluded that parvovirus-B19 can cause prolonged laryngitis and intravenous immunoglobulin treatment should be considered.
