Which of the following hematological problems may be precipitated by parvovirus?
Haemolytic crisis
aplastic crisis
Pancytopenia
Thrombocytopenia
Parvo virus responsible for causing premature destruction of precursor cells in bone marrow Premature destruction of precursor cells - aplastic crisis If an individual develops parvovirus infection the number of cells which are being destroyed are relatively less In a situation in which say for example hemolytic anemia, the number of precursor cell percentage is very high, in this situation if a person develops parvovirus infection, leads to Sudden fall in hematocrit Eg: patient with sickle cell anemia or hereditary spherocytosis, if these patients develop parvovirus infection there will be a sudden fall in the hematocrit
