title: Vertical transmission of dengue: first case report from Bangladesh.
abstract: We report a case of vertical transmission of dengue infection in a new born from Bangladesh. The mother was primigravida with an uneventful antenatal period except the fever she developed at 37 weeks of gestation. She underwent cesarean section for decreased fetal movement. The fever lasted for 7 days and was associated with intense bodyache, and a positive tourniquet test. She did not experience any hemorrhages including from the surgical wound. Her platelet count fell at its lowest to 100,000/mm3. She had bilateral mild pleural effusions and positive anti-dengue antibodies (both IgG and IgM). She received symptomatic treatment. The baby was deeply meconium stained and was resuscitated by a pediatrician. His postnatal period went well until day-3 of life when he developed fever and respiratory distress. There were no signs of meconiun aspiration syndrome (MAS) and the septic work up was negative. The platelets count fell to its lowest of 40,000/mm3 on day-3 and day-5 of his illness. Anti-dengue antibodies (both IgG and IgM) were positive with a nearly four-fold rise of IgM antibodies in the convalescent sera. The boy was treated with platelet transfusions and was discharged on day-6 after becoming ill. This report emphasizes that in a dengue epidemic or when dengue is endemic (which Bangladesh has experienced recently), a pregnant woman with fever, myalgia and/or bleeding manifestations should raise a high suspicion that the baby may develop the disease, and both the mother and baby should be closely followed-up. Viral isolation could not be done due to the unavailability of the test.
