[Familial transient red cell aplasia from parvovirus B-19 infection]

In our Paediatric Clinic we observed a case of transient aplastic crisis caused by Parvovirus B19 in a child and his mother, both affected by spherocytic haemolytic anemia. Anti-Parvovirus IgM antibody titre and viral search by PCR were positive. Anemia was treated with transfusion of concentrated red blood cells. In case of a family onset of hyperacute anemia it is necessary to consider a bone marrow aplastic crisis of the red series, induced by Parvovirus B19, especially if there is notice of an ongoing outbreak of erythema infectiosum.
