Challenges in a unique presentation of congenital dengue with congenital heart disease.

Vertical transmission of dengue has been documented and is associated with diverse presentations in newborns. Care of such babies requires meticulous support to maintain homeostasis until the baby recovers. We present a neonate diagnosed with congenital dengue, born to a mother diagnosed with dengue on the second day after delivery. Baby was diagnosed by serological tests, underwent appropriate management in neonatal intensive care but was noted to have had coexistent persistent ductus arteriosus and pulmonary hypertension complicating pneumonia and seizures. Management of the baby was complicated by persistent haematological derangements caused by dengue and haemodynamic alterations caused by the heart disease.
