Background:Dengue is the most prevalent mosquito-borne viral disease affecting humans. The present study was conducted to assess maternal and fetal complications of dengue fever in pregnancy. Materials & Methods: 96 antenatal patients diagnosed with dengue fever clinically and serologically were included. Parameters such as parity, gestational age, symptoms at the time of diagnosis, platelet count and haematocrit at the time of diagnosis were recorded. Details regarding ICU admission need for transfusion and medical examination was recorded. Maternal and fetal complications were also recorded. Results: Gestational age at diagnosis (weeks) <12 was seen among 5, 12-20 in 8, 20-28 in 14, 28-34 in 16, 34-37 in 20 and >37 in 33. Trimester I was seen in 7, II in 23 and III in 66. Platelet count <20000 was seen in 10, 21000-50000 in 22, 51000- 100000 in 20, 1 lakh- 1.5 lakh in 32 and >1.5 lakh in 12. Fetal complications were IUGR in 3, fetal malformation in 2, meconium- stained amniotic fluid in 8 and fetal distress in 5. Neonatal outcome was prematurity in 11, low birth weight in 34, ICU admission in 5 and vertical transmission in 6. The difference was significant (P< 0.05). Conclusion: There were significant maternal and fetal outcome in pregnant women suffering from dengue fever. Hence, there is need to have close monitoring of complications.
