My 6 yo son was dx with hereditary spherocytosis. i am so worried about him getting parvovirus and going into aplastic crisis. what do i watch for??

Pale=ghostlike: Most have a mild to moderate form with a variety of symptoms including mild anemia,which produces fatigue & pallor(ghost like appearance).Intermittent episodes of more profound anemia can occur, but are not silent.Whether this is after a febrile illness like parvo, or a blood trapping event in the spleen, the kids are sicker,have abdominal pain,fatigue & >pallor.All are treatable
