Parvovirus B19 induced transient aplastic crisis in an immunocompetent child.

Viral-induced aplastic crisis is an important cause of unexplained anaemia. It becomes significant in the context of an immunocompromised host. However, it is commonly overlooked in a well-nourished immunocompetent host. Parvovirus B19-induced transient crisis is one such example. Bone marrow study is a commonly performed preliminary investigation for an unexplained anaemia and can provide important morphological clues as in our case. We encountered classic Parvovirus B19 inclusions in the proerythroblasts of the marrow while looking for the cause of severe anaemia in an immunocompetent child.
