DENGUE IN PREGNANCY
DEFINITION
A mosquito-borne viral infection (caused by the dengue virus, transmitted by Aedes mosquitoes) that can occur during any trimester and sometimes result in vertical (mother-to-fetus) transmission.
CLINICAL MANIFESTATIONS
Pregnant women often present as non-pregnant: high fever, headache, muscle/joint pain, rash. Severe cases may progress to hemorrhage or shock.
Lab findings may include thrombocytopenia (low platelets), elevated liver enzymes, and hemoconcentration signaling plasma leakage.
COMPLICATIONS
For the mother:
Severe dengue is more likely than in non-pregnant women—with higher risk of pre-eclampsia, placental abruption, postpartum hemorrhage, DIC, and maternal death
For the fetus/baby:
•Increased risk of miscarriage (especially in first trimester), preterm birth, low birth weight, stillbirth, and fetal distress.
•Vertical transmission is rare (~1.6–22%), more likely in late pregnancy; when it occurs, newborns may have fever, hepatomegaly, thrombocytopenia, and severe dengue features
MANAGEMENT
• Hydration (oral when possible; IV fluids—2–4 mL/kg/hour if needed, but monitor closely to avoid pulmonary oedema).
-
• Monitoring: maternal vital signs, platelet count, hematocrit; frequent fetal monitoring (e.g., CTG, ultrasound) after 20 weeks.
• Hospital management for severe cases, with access to ICU and blood products.
• Avoid obstetric interventions (like C-sections or inductions) unless absolutely necessary due to bleeding risks.
-
• Manage preterm labor individually; tocolysis with atosiban if needed; steroids may be given for fetal lung maturation.
