Introduction: rubella is a leading cause of vaccine preventable birth defects especially in developing countries.

The neonate is born with multiple abnormalities with the triad of congenital cataract, deafness and cardiovascular abnormalities like ventricular septal defect or patent ductus arteriosus.
