ABSTRACT:
INTRODUCTION: THE EPIDEMIOLOGICAL CHALLENGE OF DENGUE IN OBSTETRICS
Arboviruses represent one of the most severe and dynamic threats to global public health, particularly in tropical and subtropical countries. Although the Zika virus has gained notoriety for its direct teratogenic effects, the impact of Dengue virus (DENV) infection during the pregnancy-puerperium cycle remains underestimated; it constitutes a high-risk obstetric condition requiring rapid diagnosis and intensive multiprofessional intervention (Braga; Cabral Filho, 2019; Hcini et al., 2024).
Pregnancy induces immunological and vascular adaptations necessary to maintain fetal semiallogeneic tolerance. However, when the dengue virus infects a pregnant woman, the resulting systemic inflammatory response interacts deleteriously with uteroplacental physiology (Rusu et al., 2026). Repercussions range from mild forms to severe clinical presentations marked by plasma leakage, shock, massive hemorrhage, placental abruption, preterm birth, and maternal-fetal death (Mota, 2012; Garavito-Pérez et al., 2025).
Despite the steady rise in dengue incidence among women of childbearing age, challenges persist regarding clinical management and safe vaccination during pregnancy, given that live-attenuated virus vaccines remain contraindicated during this period (FEBRASGO, 2025). This chapter proposes a theoretical-practical analysis of the pathophysiology of dengue during pregnancy, integrating international scientific evidence with the clinical practice experienced by the authors at the Assis Chateaubriand Teaching Maternity Hospital (MEAC/EBSERH).
