Causes
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.

gollark: This happened to me, attempting to run a hatchery with anti-sickness/viewbombing safety using data from EATW.
gollark: Technically yes. Realistically it's not enforced unless TJ09 doesn't like you.
gollark: Great idea.
