[Acute parvovirus B 19-induced erythroblastopenia and hereditary spherocytosis. Apropos of 1 pediatric case and review of the literature].

Authors report a new case of acute erythroblastopenia linked to a parvovirus B 19 infection by a 10 years old boy suffering from an hereditary spherocytosis. Aurillac antigen or parvovirus B 19 is one of the smallest virus to be known. It has been well demonstrated in vitro that the virus inhibits especially erythropoiesis but mechanism remains unclear. Systematic vaccination of all children at risk with congenital or acquired chronic haemolytic anaemia should be in the near future the best prophylaxis of parvovirus B 19 infections.
