CausesEdit

Reticulocytopenia is usually a result of viral parvovirus B19 infection, which invades and destroys red blood cell precursors and halts the red cell production.

If infection occurs in individuals with sickle cell anemia,[1] spherocytosis, or beta thalassemia, it will lead to incorporation of two anemia-induced mechanisms: decreased red cell production and hemolysis. The result is a rapid and severe anemia (aplastic crisis) which may require blood transfusion.

  • Hemolytic anemia – reduced number of red blood cells due to destruction of the cells after they were made
  • Nutritional anemia – reduced number of red blood cells due to vitamin deficiency or other dietary factors
