Three cases of hereditary spherocytosis with transient hematopoietic disorder were found in the same family and adjacent communities within a short period of time. Continuous observation of hematopoiesis in peripheral blood and bone marrow at early and convalescent stages showed that hematopoietic cells migrated to the left and erythroid hematopoiesis was inhibited, and giant basophilic primitive erythrocytes were observed. Its precursor clinical manifestations, epidemiology and bone marrow changes are in line with human parvovirus B19 infection
