Occasionally it is necessary to hospitalize a child during an aplastic crisis. No, recurrences of aplastic crisis are rare. Your child will be given a follow-up appointment to check the blood count to make sure his or her body is producing RBC's again and to make sure the blood count is back to normal. Usually just one or two extra visits are needed. If there is another child in the household with sickle cell anemia, he or she should also have a blood count since they may have an aplastic crisis too.
Parvovirus is very contagious.
