Answer to Question 2

B

Feedback
A Incorrect. Pneumococcal infection does not precipitate 80 of the cases of aplastic crisis.
B Correct. Aplastic crisis occurs when there is a decrease in erythropoiesis, despite the shortened life span of sickled RBCs and the body's need for increased RBC production. In 80 of cases, this type of crisis is precipitated by an infection with human parvovirus B-19 . The infection is self-limited, but highly contagious and warrants isolation from persons vulnerable to infection. Aplastic crisis results in severe anemia.
C Incorrect. Staphylococcus does not precipitate 80 of the cases of aplastic crisis.
D Incorrect. Streptococcus does not precipitate 80 of the cases of aplastic crisis.
