Parvovirus B19 antibodies and correlates of infection in pregnant women attending an antenatal clinic in central Nigeria.

Human parvovirus B19 infection is associated with spontaneous abortion, hydrops foetalis, intrauterine foetal death, erythema infectiosum (5th disease), aplastic crisis and acute symmetric polyarthropathy.

[Results of 2-stage correction of ventricular septal defect with severe pulmonary hypertension].
