Final answer:
Parvovirus B19 is associated with aplastic anemia in patients with sickle cell anemia. It is known for causing transient aplastic crisis by infecting and destroying RBC precursors.
Step-by-step explanation:
The virus that is associated with aplastic anemia in patients with sickle cell anemia is Parvovirus B19. Although not explicitly mentioned in the reference information provided, Parvovirus B19 is well-known in the medical community for its association with transient aplastic crisis in patients with conditions like sickle cell anemia. Aplastic anemia itself is a condition characterized by a deficiency of red blood cell (RBC) stem cells, which can result from inherited factors, environmental exposures such as radiation and certain medications, as well as from infections. In the context of infection, Parvovirus B19, a virus from the erythrovirus family, has been identified as a common cause of aplastic crisis in individuals with sickle cell disease, due to its propensity to infect and destroy precursors of red blood cells.
