A 23-year-old woman with term pregnancy was admitted in our hospital with high fever, headache and myalgia for 7 days. Dengue NS1 antigen and IgM antibodies against dengue virus were positive, whereas IgG antibody test was negative. She delivered on the 3rd day of admission, and had severe postpartum hemorrhage, subconjuctival hemorrhage, and bilateral pleural effusion. Severe thrombocytopenia was present (platelet count 8×10⁹/L). Repeated transfusions of blood, fresh frozen plasma and platelets were needed. Platelet count started rising on the 4th postnatal day, and after that she gradually recovered. A female baby was delivered vaginally on day-6 of maternal illness; birth weight was 2.7 kg, and APGAR scores were 7/10 and 9/10 at 1 and 5 minutes, respectively.

Petechial lesions were noted on day-11; platelet count was 10×10⁹/L. Platelet transfusions and supportive management were provided.
